County & School Selection and Change Lens Methodology
How the ten founding counties and schools are selected, and how the Change Lens diagnostic identifies strengths, barriers and implementation priorities without ranking or inspecting schools. One Big Change Kenya, September-December 2026.
This Appendix sets out the methodology for:
- selecting the ten founding counties
- selecting one founding school within each county
- ensuring the founding cohort reflects materially different Kenyan education contexts
- completing the One Big Change Change Lens
- identifying school strengths, barriers and implementation priorities
- distinguishing evidence from perception
- protecting schools from inappropriate ranking or comparison
- translating diagnosis into practical action
- using the founding evidence to inform the proposed Year 1 national programme
The methodology is designed to ensure that the founding phase tests the One Big Change model across different operating environments rather than simply selecting ten convenient or high-performing schools.
The founding cohort will comprise:
10 schools in 10 different Kenyan counties, deliberately selected to expose the programme to different implementation realities.
The purpose is not statistical representation of every Kenyan school within a ten-school sample. The purpose is purposeful implementation testing. The cohort should allow the programme to ask:
- Does the model work in urban and rural settings?
- Does it remain useful in higher-resource and lower-resource environments?
- Does it help schools facing infrastructure constraints?
- Does it add value where school leadership is already strong?
- Does it work where specialist capability is scarce?
- Can the same implementation framework adapt without becoming a one-size-fits-all intervention?
- What parts of the model should remain common nationally?
- What must be adapted locally?
3. What the Founding Sample Is Not
The founding cohort is not intended to:
- rank counties
- rank schools
- identify Kenya's "best" or "worst" schools
- establish a nationally representative research sample
- distribute programme places politically
- provide equal geographic representation across all regions
- favour schools because they are easiest to access
- favour schools because they already have strong external relationships
- select schools solely because they are likely to produce positive results
A school experiencing significant implementation challenges may be as valuable to the founding evidence as a school demonstrating strong practice.
The ten counties should collectively expose the programme to a broad range of implementation conditions.
Each county should contribute a distinct contextual learning opportunity.
The county framework therefore uses education context, not ethnicity, tribe or political affiliation, as the basis for selection.
The ten founding county contexts are:
| Context Type | What the Programme Needs to Learn |
|---|---|
| Major urban | How scale, density, inequality and institutional complexity affect implementation |
| Fast-growing peri-urban | How rapid population growth and infrastructure pressure affect school readiness |
| Coastal | How local geography, community context and economic circumstances influence implementation |
| Rural agricultural | How rural access, local livelihoods and infrastructure influence implementation |
| Arid or semi-arid | How resource constraints and geographic conditions affect implementation |
| Remote or frontier | How distance, staffing and infrastructure constraints affect school capability |
| Strong-performing education environment | What existing good practice can be identified and transferred |
| Lower-resourced environment | What minimum implementation infrastructure schools require |
| Technical or industrial potential | How pathways, STEM and employer relationships can contribute |
| Strong institutional influence | How universities, public institutions and networks can strengthen implementation |
One county may exhibit more than one characteristic. The framework is therefore intended to guide selection rather than force counties into artificial single categories.
An initial working long-list may include:
These counties are proposed for validation. They are not presented as final founding counties until:
- appropriate Kenyan stakeholders have been consulted
- school-access considerations have been assessed
- logistical feasibility has been reviewed
- contextual diversity has been confirmed
- potential founding schools have been assessed
Alternative counties may be substituted where they better meet the founding objectives.
Each proposed county will be reviewed against the following criteria.
| Criterion | Description |
|---|---|
| Contextual Distinctiveness | Does the county expose the programme to a meaningfully different implementation environment? |
| Educational Relevance | Does the context provide useful evidence regarding CBE, CBC or CBA implementation? |
| School Diversity | Are there appropriate candidate schools capable of contributing useful evidence? |
| Access and Feasibility | Can the founding programme deliver meaningful fieldwork within the 90-day window? |
| Institutional Connectivity | Are appropriate education institutions or networks available to support implementation where needed? |
| Replicability Value | Could lessons generated have relevance beyond the selected county? |
| Resource Context | Does the county contribute useful evidence regarding differing levels of resources or infrastructure? |
| Pathway Relevance | Does the location provide useful insight into Senior School pathways, technical/STEM or other implementation questions? |
| Learning Value | What unique question would inclusion of this county help the programme answer? |
For programme-management purposes, candidate counties may be assessed using a simple internal matrix. Each criterion may receive:
3
Strong contribution
2
Moderate contribution
1
Limited contribution
0
Does not materially contribute
The scoring matrix is a decision-support tool. It is not intended to create a public ranking of counties.
The final decision should combine:
Before the final ten counties are confirmed, the programme team should ask:
- Have we over-selected urban environments?
- Have we included materially lower-resource contexts?
- Have we included at least one remote or frontier environment?
- Are different infrastructure conditions represented?
- Are different school-system challenges represented?
- Are we exposing the model to sufficiently different implementation barriers?
- Are travel requirements manageable within the commissioned budget?
- Does every selected county add something the other nine do not already provide?
A county should not be retained simply because it appeared in the initial proposal.

County and school selection prioritises materially different contexts over convenience or prestige.
Within each selected county, one founding school will be selected. The school must be capable of participating meaningfully in the entire 90-day programme while contributing useful implementation evidence.
The objective is to select schools that are:
- sufficiently ready to engage
- sufficiently diverse to test the model
- honest about barriers
- able to act on an agreed priority
- willing to gather evidence
- willing to learn with other schools
A school must normally meet the following minimum conditions.
Leadership Commitment
A senior leader agrees to act as programme sponsor.
Named School Champion
A member of staff is given sufficient responsibility and time to coordinate implementation.
Evidence Contact
A person is identified to support baseline and implementation evidence.
Programme Availability
The school can participate throughout the founding phase.
Willingness to Learn
The school is prepared to identify both strengths and weaknesses.
Implementation Capacity
The school can reasonably undertake at least one practical change during the founding period.
Evidence Participation
The school is prepared to gather proportionate evidence.
Peer Learning
The school is willing to share learning with the other founding schools.
Safeguarding and Data Compliance
Participation can occur within agreed safeguarding, consent, data and ethical requirements.
Eligible schools may then be assessed against the following criteria.
| Criterion | Question |
|---|---|
| Leadership Engagement | Is senior leadership genuinely committed? |
| Champion Capacity | Is there a credible person able to coordinate implementation? |
| Evidence Readiness | Can the school provide and collect appropriate evidence? |
| Contextual Relevance | Does the school add useful learning to the national founding cohort? |
| Implementation Need | Is there a meaningful implementation challenge the programme may help address? |
| Strengths to Share | Does the school also have useful existing practice others might learn from? |
| Staff Engagement | Is there sufficient willingness among relevant staff to participate? |
| Sustainability | Is there reasonable potential for change to continue after external support reduces? |
| Peer Potential | Could the school eventually contribute to local peer support or Hub development? |
| Feasibility | Can meaningful work be completed within the founding period? |
The programme may use a structured internal scoring approach. Suggested scale:
Not demonstrated
Evidence is absent.
Limited
Some evidence exists but significant concern remains.
Adequate
The requirement is sufficiently demonstrated.
Strong
There is clear evidence of strong suitability.
Selection should not simply go to the ten schools with the highest numerical scores. The score assists judgement. Final cohort composition must also protect contextual diversity.
A school may be deferred where:
- leadership commitment cannot be confirmed
- programme participation is likely to create excessive burden
- safeguarding concerns cannot be appropriately managed
- required evidence cannot be accessed ethically
- implementation cannot reasonably occur within the timetable
- participation is being sought primarily for prestige rather than implementation
- the programme would duplicate substantial existing intervention without additional value
- a conflict of interest cannot be appropriately managed
Deferment is not a judgement of school quality. It simply means the school may not be suitable for this particular founding phase.
The proposed process is:
Step 1 - County confirmed
↓
Step 2 - Candidate schools identified
↓
Step 3 - Initial information reviewed
↓
Step 4 - Leadership conversation
↓
Step 5 - Readiness assessment
↓
Step 6 - Context and cohort-balance review
↓
Step 7 - Programme selection
↓
Step 8 - Participation agreement
↓
Step 9 - Sponsor, Champion and Evidence Contact confirmed
↓
Step 10 - School onboarding begins
School selection should involve appropriate consultation but remain sufficiently controlled to protect programme integrity. Potential inputs may come from:
- relevant public institutions
- school networks
- education leaders
- Advisory Committee members
- universities
- local education stakeholders
An introduction does not guarantee selection.
Every proposed school must pass the same readiness and suitability process.
Any individual participating in school selection should disclose relevant relationships. Examples include:
- family relationships
- employment relationships
- commercial relationships
- governance positions
- financial interests
- political interests
A material conflict may require that person to withdraw from the relevant decision.
The Change Lens is the core school-level implementation diagnostic used by One Big Change. It is designed to help schools answer:
What is working, what is getting in the way, what matters most now, and what support would make the greatest practical difference?
It is not:
- an inspection framework
- a compliance scorecard
- a league table
It does not replace:
- Government inspection
- curriculum
- assessment
- quality-assurance functions
The Change Lens has five purposes.
Understand
Build a structured picture of the school's implementation context.
Prioritise
Prevent schools from trying to solve every problem simultaneously.
Connect
Identify the expertise, resources and partners required.
Implement
Translate insight into a practical school-level action.
Learn
Generate evidence regarding what changed and why.
The Change Lens works through the sequence:
Listen
↓
Understand
↓
Prioritise
↓
Act
↓
Evidence
↓
Learn
↓
Sustain
This is the operational heart of the One Big Change model.
The founding Change Lens may examine up to ten interconnected domains.
Leadership and Governance
Possible questions include:
- Is the school's implementation direction understood?
- Are responsibilities clear?
- Is implementation actively reviewed?
- Does leadership create time and space for change?
- Are staff able to raise barriers?
Teacher Capability and Professional Learning
Possible questions include:
- How confident are teachers in relevant CBE/CBC/CBA practice?
- What professional development has occurred?
- Has training changed classroom practice?
- Where is additional support required?
- Is peer learning taking place?
Teaching and Learning
Possible areas include:
- lesson design
- learner participation
- competency development
- differentiation
- feedback
- practical learning
- classroom implementation
Curriculum and CBE Readiness
Possible areas include:
- curriculum interpretation
- pathway delivery
- subject capacity
- practical requirements
- timetabling
- staffing
- implementation confidence
Competency-Based Assessment
Possible areas include:
- assessment understanding
- formative assessment
- evidence collection
- feedback
- recording
- moderation
- teacher workload
- use of assessment information
Inclusion and Access
Possible areas include:
- identification of learner needs
- barriers to participation
- SEND/inclusion practice
- adaptations
- specialist support
- equitable access to pathways and learning
Learner and Staff Wellbeing
Possible areas include:
- learner wellbeing
- teacher wellbeing
- referral mechanisms
- workload
- attendance
- psychological safety
- support systems
Family and Community Engagement
Possible areas include:
- parental understanding of CBE
- pathway understanding
- communication
- family engagement
- community relationships
- employer/community involvement
Resources, Infrastructure and Technology
Possible areas include:
- classrooms
- equipment
- laboratories
- devices
- connectivity
- digital systems
- learning materials
- transport or infrastructure barriers
Pathways, Partnerships and Sustainability
Possible areas include:
- Senior School pathways
- employer relationships
- universities
- technical institutions
- community partners
- future capability
- school-to-school learning
- sustainability
For public communication, the framework may also be summarised through four broad pillars:
Leadership & Professional Capability
Wellbeing
Inclusion
Teaching, Learning & Academic Quality
The detailed ten-domain diagnostic sits underneath these broad public-facing pillars. This allows the programme to communicate simply without oversimplifying the implementation work.
The Change Lens should not rely on one person's opinion. Evidence may include:
- senior leadership interviews
- teacher conversations
- champion interviews
- document review
- existing school data
- classroom observation where appropriate
- staff questionnaires
- learner voice where ethically appropriate
- parent/community input where relevant
- assessment information
- attendance or participation information
- professional-development records
- infrastructure review
- implementation records
Not every source will be required for every domain. Evidence should be proportionate to the question being investigated.
Where practical, a material finding should be supported by more than one source.
For example, a statement that teachers lack confidence in CBA should not rely solely on one leadership interview. Evidence might combine:
- teacher questionnaire
- teacher discussion
- professional-development records
- implementation observation
Triangulation helps distinguish perception from repeated evidence.
The founding programme should avoid simplistic numerical league-table scoring. Instead, each domain may use an implementation maturity description.
Established Strength
Practice is functioning consistently and may contain learning for others.
Developing
Useful practice exists but is not yet consistent.
Priority for Strengthening
A meaningful barrier is limiting implementation.
Significant Constraint
The issue materially prevents effective implementation and may require external support.
Further Evidence Required
The programme does not yet have enough evidence to reach a responsible conclusion.
These ratings support implementation decisions. They are not school grades.
The Change Lens will not produce:
- an overall school percentage
- a national ranking
- a county ranking
- a public league table
A school may be strong in one domain and face significant constraints in another. Reducing this to one score would obscure the very information the programme needs.
The Change Lens must identify existing strengths as well as barriers. Each school baseline should document:
- what is working
- why it appears to work
- who is making it work
- whether it could be strengthened
- whether other schools could learn from it
The programme is therefore not based solely on deficit identification. Schools are also potential sources of solutions.
The Change Lens may identify several barriers. The school should normally select one primary One Big Change priority during the founding phase. The priority should satisfy most of the following conditions:
- important to implementation
- meaningful to the school
- capable of action within the founding period
- measurable
- supported by leadership
- relevant to learners or staff
- capable of producing useful learning
- not already adequately addressed by another intervention
- potentially sustainable
- potentially useful to wider national learning
A proposed priority may be assessed against:
| Dimension | Question |
|---|---|
| Importance | How materially does this issue affect implementation? |
| Urgency | What happens if it is not addressed? |
| Feasibility | Can meaningful progress occur within 90 days? |
| Evidence | Can change be measured responsibly? |
| Ownership | Will the school own the work? |
| Sustainability | Can the change continue? |
| Learning Value | Will the result inform wider implementation? |
| Resource Requirement | Is the required support realistic? |
Every selected priority should translate into an implementation pathway. The pathway should contain:
Problem Statement
What is currently happening?
Evidence
How do we know?
Desired Change
What should be different?
Actions
What will the school and programme do?
Owner
Who is responsible?
Support
What expertise or resources are required?
Evidence Measure
How will we know whether implementation changed?
Review Date
When will progress be assessed?
Sustainability
What happens after the founding phase?
Each founding school should therefore leave the Change Lens process with a concise implementation plan containing:
Where programme-funded resources are required, access to the School Implementation Activation Fund should follow the evidence. The sequence is:
Change Lens
↓
Identified Priority
↓
Approved Implementation Plan
↓
Costed Requirement
↓
Approval
↓
Procurement / Resource Deployment
↓
Implementation
↓
Evidence
Funding should not precede diagnosis merely because a school requests equipment or services.
The same principle applies to external resources.
The Change Lens identifies the barrier. The Traction Partner helps remove it.
Potential partner support should therefore map directly to:
- identified need
- approved implementation action
- expected use
- evidence requirement
- accountable owner
A partner should not dictate the school's One Big Change simply because it has a product or budget available.
Experts follow the same needs-led model. The process should be:
Barrier identified
↓
Capability gap defined
↓
Required expertise specified
↓
Suitable Kenyan expertise considered first
↓
Relevant African expertise considered
↓
International specialist expertise added where it provides clear additional value
The programme should not import solutions merely because international experts are available.
Where international specialists participate, the programme should seek opportunities to pair them with Kenyan practitioners or institutions. The objective is:
- knowledge transfer
- local ownership
- reduced dependency
- creation of Kenyan implementation capability
The programme should become more locally capable as it scales, not more internationally dependent.
Change Lens findings feed directly into MicroSummits.
First MicroSummit
Should help schools:
- understand the evidence
- refine the priority
- identify existing strengths
- learn from other perspectives
- develop the implementation plan
Second MicroSummit
Should help schools:
- review implementation
- examine evidence
- understand what changed
- identify what still blocks progress
- agree the next step
- identify what should be shared nationally
After the ten baselines are complete, the programme will produce a cross-site analysis. This should distinguish:
Common Barriers
Issues repeatedly appearing across several schools.
Contextual Barriers
Issues strongly linked to local circumstances.
Strong Practice
Practices already working well and potentially transferable.
Capability Gaps
Areas where schools require specialist expertise.
Resource Gaps
Equipment, infrastructure or technology requirements.
System Questions
Issues potentially requiring consideration beyond an individual school.
Further Evidence Needs
Questions the founding phase cannot yet answer.
The cross-site analysis should not say:
"County X performs better than County Y."
It should say:
"Across the ten founding contexts, these implementation patterns repeatedly appeared, while these challenges were context-specific."
The focus is implementation learning.
The programme should agree with participating institutions what information may be:
- publicly attributed
- anonymised
- aggregated
- kept confidential
Internal programme evidence may require school-level identification. Public reports should avoid unnecessary disclosure of sensitive weaknesses. Schools should be encouraged to be honest without fearing reputational punishment for participating.
The Change Lens should collect only information reasonably necessary for the agreed implementation purpose. The programme should avoid unnecessary collection of:
- personally identifiable learner data
- health information
- safeguarding information
- special-category data
Where such information is legitimately required, appropriate legal, ethical, safeguarding and data controls must apply. Detailed requirements are contained in Appendix 6 - Risk, Safeguarding, Data Protection & Ethics.
Every school baseline should undergo quality assurance before being finalised. The review should test:
- evidence sufficiency
- clarity
- neutrality
- triangulation
- distinction between facts and interpretation
- meaningful identification of strengths
- actionable barriers
- suitability of priority
- appropriateness of proposed evidence measures
A baseline should not be accepted simply because the field visit took place.
Before finalisation, the school should have an opportunity to:
- review factual information
- correct errors
- provide missing evidence
- challenge unsupported interpretations
- confirm the selected priority
This does not mean the school can remove uncomfortable but well-supported findings merely because it dislikes them. It means the diagnostic should be accurate and fair.
For each school, the Change Lens should produce:
Output A
School Context Summary
Output B
Strengths Profile
Output C
Implementation Barrier Profile
Output D
Selected One Big Change Priority
Output E
Implementation Plan
Output F
Capability and Expertise Requirement
Output G
Resource Needs Profile
Output H
Evidence Plan
Output I
Sustainability / Next-Step Plan
Across the ten schools, the Change Lens should produce:
- one ten-school evidence dataset
- one cross-site implementation analysis
- one common-barrier map
- one contextual-barrier map
- one strong-practice library
- one capability-needs map
- one resource-needs matrix
- one Traction Partner opportunity map
- one potential Hub-readiness picture
- one set of recommendations for Year 1 methodology
The founding programme may also examine whether individual schools show characteristics consistent with future Hub leadership. Possible indicators include:
- stable leadership
- strong implementation ownership
- willingness to support peers
- useful practice to share
- sufficient coordination capacity
- evidence discipline
- positive peer relationships
- commitment to train-the-trainer
- geographic/logistical suitability
Hub identification during the founding phase remains provisional. No school should be promised Hub status simply by participating as a founding school.
The ten-school founding phase must help determine:
The founding phase therefore tests the methodology itself, not only the schools.
47. Adaptation Before National Scale
The founding Change Lens should not be assumed to be the final national version. At the Decision Gate, each element should be reviewed against:
- usefulness
- burden on schools
- evidence quality
- clarity
- implementation value
- cost
- scalability
The Year 1 Change Lens may therefore be retained, simplified, expanded in specific areas, digitised further, or adapted for different school contexts.
The programme may use digital tools to support:
- data collection
- evidence upload
- school dashboards
- progress tracking
- resource matching
- implementation plans
- RAG reporting
- Hub learning
- partner reporting
Technology supports the methodology. It does not replace professional judgement or school conversation.
49. School Burden Principle
The programme should avoid creating unnecessary reporting burden. Where reliable information already exists, the programme should seek to use it rather than ask schools to recreate it. The Change Lens should concentrate on information required for:
- implementation decisions
- evidence
- learning
- scale design
September
- methodology finalisation
- school onboarding
- champion training
- pre-baseline information
October
- ten in-person baseline processes
- evidence gathering
- school validation
- first MicroSummits
- priority selection
November
- implementation
- evidence collection
- support
- resource matching
- peer learning
December
- review
- second MicroSummits
- outcome evidence
- sustainability planning
- cross-site analysis
- methodology review
- Decision Gate
No recommendation for national scale should rely simply on:
- testimonials
- attendance numbers
- photographs
- stakeholder enthusiasm
- number of meetings
- amount of partner interest
The Decision Gate should examine:
- completed baselines
- implementation actions
- before/after evidence where appropriate
- school-level outcomes
- capability development
- cost
- resource mobilisation
- contextual differences
- implementation failures
- methodological limitations
- sustainability evidence
52. Learning from Failure
An implementation cycle that does not produce the intended result is not automatically a programme failure. It may provide highly valuable evidence if the programme can establish:
- what was attempted
- why it was selected
- what happened
- why it did not work
- what should change
- whether the approach should be abandoned or redesigned
The programme should therefore reward honest learning rather than encourage schools or programme staff to hide unsuccessful interventions.
53. No-Performance-Theatre Principle
The methodology is designed to reduce incentives for schools or programme staff to demonstrate artificial success. Programme reporting should therefore distinguish:
activity
↓
implementation
↓
outcome
↓
impact
- A successful event is not automatically successful implementation.
- A completed training session is not automatically changed classroom practice.
- A delivered device is not automatically improved learning.
Evidence must follow the full implementation chain.
The Change Lens will be considered effective if, by the end of the founding phase, it has enabled schools and programme leaders to answer:
