How should evidence change from teacher to board?

A teacher knows a student. A head knows a school. A board holds the school accountable. Each of those roles needs evidence, but not the same evidence, presented in the same way. The practical question is: how should what you know about your students change form as it moves from classroom to corridor to boardroom, without losing what matters or overwhelming those who are reading it?

The answer is not to simplify at the top and detail at the bottom. It is to present evidence at the right altitude for the decision being made, while keeping a traceable thread back to the source. A board member does not need a student's reading log. A class teacher does not need a finance committee briefing. But the understanding that sits behind both should come from the same coherent body of evidence.

This piece is for heads and principals who are trying to build that coherence, and for the senior leaders and governors who need to trust it.

In short

• Evidence about students should change altitude as it rises from teacher to head to board, but it should remain traceable to the same underlying sources.
• Teachers need student-level evidence to act; heads need pattern-level evidence to lead; boards need assurance, not operational data.
• Resetting evidence at the end of each year discards institutional memory and forces teachers to start again with students they have not met.
• Student voice, teacher observation, specialist insight, family context and formal assessment are the raw material. Strategy and governance views are derived from these, not a separate kind of evidence.
• The risk of not structuring how evidence changes altitude is that the same information becomes either overwhelming or invisible, depending on who is reading it.

Why altitude matters in a school

Altitude, here, means the level at which evidence is read and the decision it supports. A class teacher reading a student's written work is operating at the lowest and most specific altitude. A head reviewing how Year 10 is performing across subjects is operating higher. A board asking whether the school's pastoral model is producing the outcomes it promises is higher still.

Each altitude is legitimate. The problem comes when evidence is not adjusted for the reader. Raw student data handed to a board is noise. A summary trend handed to a teacher is almost useless. The information needs to travel, and it needs to change as it does.

This is not about hiding detail from leaders or governors. It is about giving each person what they need to make a good decision, with enough traceability that they can ask for more if the situation demands it.

What the evidence actually is

Before thinking about altitude, it helps to be clear about what the evidence is. In a school, genuine evidence about a student comes from a small number of sources: what the student says about their own learning (student voice), what teachers observe in class and across time (teacher observation), what formal assessments show (formal assessment), what specialists such as learning support staff or counsellors contribute (specialist insight), and what families bring about context at home (family context).

These five sources are not equal in every situation, and they do not always agree. A student may report confidence in an area where a teacher observes persistent difficulty. A family may hold context that explains both. The value of holding all five together is that the full picture is more reliable than any single reading.

Cook-Sather (2006) argues that student voice work rests on the conviction that young people have unique perspectives on learning and schooling, and that their insights warrant the attention and the response of adults. Including student voice as a genuine source, rather than an add-on, changes the character of the evidence base.

What heads and boards see, at their altitude, is a reading derived from these five sources. It is not a sixth kind of evidence. That distinction matters, because it means governors cannot be briefed on something that has no connection to what teachers are actually observing.

How evidence should change altitude from teacher to head to board

The table below describes what each role needs, the decision it supports, and the risk if the evidence is not calibrated correctly.

Role	What they need	The decision it supports	Risk if miscalibrated
Class teacher	Individual student profile: history, patterns, specialist notes, family context	How to plan for this student this term	Starts each year blind; repeats what did not work
Head of year or section principal	Patterns across a year group or section; where the spread is widening or narrowing	Where to direct staff attention and resources	Responds to crises rather than patterns; misses the early signal
Head of school or principal	School-wide view of delivery against educational priorities; briefing-level synthesis	How to lead the school and answer to the board	Over-manages operationally; under-leads strategically
Board	Assurance that priorities are being met; challenge where evidence is thin or unclear	Governance: holding the school accountable without running it	Either rubber-stamps or micro-manages; neither is governance
Finance committee	Investment implications of educational priorities	Whether resource allocation reflects stated educational commitments	Decisions disconnected from what is actually happening in classrooms

The annual reset problem

Many schools, even well-run ones, lose what they know about students at transition points. A new teacher inherits a class and starts afresh. A student moves from junior to senior school and is, in effect, a new arrival in the system. The handover note exists, if it exists at all, as a brief paragraph or a conversation in a corridor.

This is an institutional memory problem, not a staffing one. Individual teachers carry knowledge that belongs to the school, and when they leave or when a student moves on, that knowledge often leaves with them.

The consequence is not just inefficiency. It is that understanding has to be rebuilt from scratch, and the student experiences that rebuilding as a kind of invisibility. A student who needed a particular approach in Year 7 should not have to earn that understanding again in Year 8. The evidence should travel with them.

Cumulative understanding, rather than annual resets, is what turns individual observations into institutional knowledge. A student who has moved on is archived, not erased. The years they were at the school remain part of the record.

What good evidence practice looks like at the head's level

A head's job is to lead delivery and answer to the board. That requires a synthesis of what is happening across the school, grounded in evidence that is traceable but not overwhelming. A head reading a briefing should be able to see where things are going well, where the evidence is thin, and where a pattern warrants attention, without having to read every student profile.

Hattie and Timperley (2007) found that feedback is among the major influences on learning, but that its effect can be positive or negative depending on the type and how it is given. The same is true of the information a head receives. A well-constructed briefing supports better decisions. A poorly constructed one, or none at all, leaves leadership to instinct and anecdote.

At the head's level, the most useful evidence is patterned and comparative: how is this year group performing against where they were last term, last year, and against the school's own stated priorities? That pattern view requires cumulative data, not a snapshot.

What governance requires, and what it does not

Boards are often given too much operational detail or too little grounded evidence. A board that receives raw student data is being asked to do the head's job. A board that receives only assurances without traceable evidence cannot challenge effectively.

Governance requires assurance and challenge. Assurance means the board can see that the school's educational priorities are being met and that the evidence supports that claim. Challenge means the board can ask a question and expect an answer grounded in evidence, not opinion.

Finance committees have a specific version of this need. They are not looking at attrition forecasts or enrolment predictions. They are asking whether the resources allocated to particular programmes reflect what the school says its educational priorities are. That is a question about the investment implications of educational choices, and it requires evidence from the classroom, translated into the right language for a finance conversation.

Questions worth asking

• When a student moves year group or section, what evidence travels with them and who is responsible for making sure it does?
• Does your board receive evidence that is traceable to what teachers are actually observing, or does it receive summaries that have lost that connection?
• When you brief the board, could you answer a follow-up question with a concrete example from the evidence, or would you need to go away and find one?
• Is the evidence your heads of year or section principals hold structured consistently across the school, or does it depend on individual practice?
• If a teacher leaves this term, what knowledge about their students stays in the school?
• Does your finance committee understand the educational priorities well enough to evaluate whether the budget reflects them?

FAQ

Is it realistic to keep evidence about students across multiple years without creating an unmanageable system?

It is realistic if the structure is clear and the inputs are defined. The problem most schools face is not too much evidence but too little organisation of the evidence that already exists. Five consistent sources, held in a structured way, are manageable. The discipline is in deciding what counts as evidence and making sure it is recorded in the same way across the school.

Should boards see individual student information?

No. Boards operate at the governance level, which means assurance and challenge around whether the school's educational priorities are being met. Individual student information is operational detail. A board that is reading individual profiles is doing the head's job, and that is not governance. The board's evidence should be derived from student-level data, not composed of it.

How do we stop evidence from becoming a burden on teachers?

The key is that teachers record what they are already observing, in a way that is usable rather than performative. Evidence that serves only reporting purposes is a burden. Evidence that travels with a student, informs the next teacher, and surfaces at the right level for leadership has a clear purpose. The structure has to justify the effort.

What is the risk of presenting evidence differently at each level?

The risk is a loss of traceability: if the board's picture is too detached from what teachers are observing, governance becomes disconnected from reality. The answer is not to give everyone the same view but to maintain a clear and auditable thread from classroom observation to leadership briefing. Each level should be able to ask for more detail and get a coherent answer.

Does student voice belong in a leadership briefing?

Student voice is one of the five evidence sources, and it should inform every level of the briefing, including the head's synthesis and the board's assurance view. It does not appear as raw student comment at the board level, but the patterns in what students report about their own learning are part of the picture the board is being given. Leaving it out produces a partial view.
