Ofsted inspection preparation: a guide for school and trust leaders

Reviewed by Ben Parnell, former headteacher and trust chief executive. Last reviewed 12 September 2026.

Ofsted inspection preparation means keeping your self-evaluation current and honest all year, knowing exactly where your evidence gaps are, and having a plan for the notification call, the inspection days and the draft report that follows. There is no single document or format Ofsted expects to see. What inspectors look for is whether leaders already know their school as well as the inspection team is about to.

This guide sets out the whole process in order: what to do long before an inspection is called, what happens on the phone, what happens across the inspection days, and what happens after the team leaves. Each stage links through to a fuller guide, because each one has its own detail worth getting right.

What does Ofsted inspection preparation actually involve?

Under the framework in use from September 2026, inspectors judge schools against three broad questions: how well pupils achieve, how well they belong, and how well they thrive. Judgements are then reported across separate evaluation areas, typically curriculum and teaching, achievement, attendance and behaviour, personal development and wellbeing, inclusion, and leadership and governance, with early years and sixth form or post-16 provision graded where they apply. Safeguarding is reported on its own as met or not met.

Each evaluation area carries its own grade on a five-point scale: urgent improvement, needs attention, expected standard, strong standard and exceptional. There is no single overall word or number for the school any more. That change matters for preparation, because it means leaders need evidence that stands up area by area, not one tidy narrative that covers everything at once. Ofsted publishes annual updates to the toolkit behind this system, most recently in June 2026 for use from September 2026, so it is worth checking the current version rather than working from an older copy.

How do I prepare long before the call?

The honest answer is that preparation should not look like exam revision. Ofsted has been explicit that it does not expect a written self-evaluation form, and says leaders "will not be at a disadvantage if they do not have a written self-evaluation." What it does expect is that leaders can talk fluently, with evidence, about how well pupils are doing and where the school still has work to do.

In practice that means three ongoing habits rather than a pre-inspection scramble.

Keep evidence current. Attendance data, behaviour logs, curriculum documents and safeguarding records should reflect this term, not last year's version tidied up for a visit. Inspectors check what leaders say against what the data and the paperwork actually show, so a gap between the two is more damaging than the gap itself.

Be honest about weak spots. A school that can name its own areas for development, with a credible plan already underway, reads differently to inspectors than one caught off guard by a question it should have anticipated. If a subject is under-resourced or a cohort's progress has dipped, say so and show what is being done.

Know your evaluation area by evaluation area. Because grading now runs by area rather than as one overall judgement, it helps to hold a short, current summary for each one. Our companion guide on the Ofsted report card and the five-point scale walks through what evidence tends to sit behind each grade.

What happens when Ofsted rings?

Ofsted notifies schools of an inspection by telephone, usually between 9.30am and 10am on the Monday of the inspection week, or the following day after a bank holiday or school closure. The lead inspector asks to speak to the headteacher or the most senior leader available, confirms that the school will tell its governing body and, where relevant, its local authority or trust, and gives leaders the chance to flag anything the team should know before arriving. A confirmation email follows with a document list and questionnaire links.

That call is short and it sets the tone for the days that follow, so it is worth having thought through in advance what you want the lead inspector to know before they are in the building. Our guide to the Ofsted notification call covers what to expect on the phone and how to use those first few minutes well.

What happens during the inspection days?

Once inspectors are on site, most evidence comes from learning walks, work scrutiny and conversations with leaders, staff and pupils. Leaders still talk about "deep dives", but the phrase has gone from Ofsted's September 2026 operating guide. Inspectors now agree the curriculum areas they will focus on during the planning call, taking account of what leaders say about strengths and the subjects where there is more to do, then explore those areas through extended learning walks and a focused conversation with the leaders responsible.

Leaders are usually kept informed as the days progress through short "keeping in touch" meetings with the lead inspector, often around the middle of the day, where emerging lines of enquiry are shared before anything is finalised. These are a genuine chance to correct a misunderstanding early, not just a formality.

Subject leaders carry much of the evidence burden in a deep dive and benefit most from proper rehearsal, not generic tips. Our guide to deep dive questions and curriculum conversations sets out what inspectors tend to probe and how subject leaders can prepare without over-scripting themselves.

What happens after the inspection ends?

Ofsted usually sends a draft report within 18 working days of the end of the inspection. From that point, leaders have five working days to respond, either raising minor points about factual accuracy or clarity, or submitting a formal complaint about the inspection itself. These two routes are not normally both available for the same report, so it is worth being clear early which one applies. The final report is usually issued within 30 working days of the end of the inspection and published within 38 working days.

Getting this stage right is mostly about discipline: read the draft against your own records line by line, separate genuine factual errors from findings you disagree with, and raise only what you can evidence. Our guide to the factual accuracy check sets out how to run that process well, and our guide to the report card and five-point scale explains how the published report card will present your results once the final report is out.

What should a multi-academy trust standardise centrally?

Inspection of individual academies still happens school by school, not trust by trust. Full inspection of multi-academy trusts as single entities has been proposed but is not expected before the 2027 to 2028 academic year, so for now the practical job for a central team is making sure every school in the trust is ready on its own terms, without duplicating effort school by school.

A few things are worth standardising centrally rather than leaving to each school to work out for itself.

A shared evidence library, so every school keeps self-evaluation notes, curriculum documents and safeguarding audits in a common structure, and a school facing a sudden Monday morning call is not starting from a blank page.

A consistent safeguarding audit cycle. Safeguarding is graded separately as met or not met, and a single not met judgement in any school affects how the trust is seen, so central teams are well placed to run a common audit calendar and check that actions from the last audit have actually closed.

A clear role for the central team on the day. The Confederation of School Trusts' guidance on inspecting school groups describes central team members being available throughout an inspection to give context on the support the trust has provided and to help signpost inspectors to the school's current position through the trust's own audit systems. Deciding this in advance saves confusion when the call comes.

A single, calm escalation route for factual accuracy and complaints, so a busy headteacher is not managing the five working day response window alone at short notice.

Ofsted inspection preparation checklist for 2026

Check you are working from the toolkit in force from September 2026, not an earlier version
Hold a short, current evidence summary for each evaluation area rather than one long self-evaluation document
Make sure attendance, behaviour and safeguarding records reflect this term's reality
Identify your two or three weakest areas honestly, with a live plan already underway
Agree who takes the notification call and what they need to say in those first minutes
Rehearse subject leaders for deep dive conversations using real curriculum documents, not generic question lists
Agree in advance who reviews a draft report and how the five working day window will be managed
For trusts, confirm the central team's role on inspection day and who owns the factual accuracy process

How InspectReady helps

InspectReady was built by people who have sat on the other side of these inspections themselves. It reviews your school's own evidence, such as your IDSR and supporting documents, to help build evidence checklists and rehearsal materials, including role specific rehearsal questions for subject leaders, SENCOs, safeguarding leads and governors, and scripts for the notification call itself. During the inspection it can track keeping in touch meetings as they happen, and afterwards it helps leaders separate genuine factual errors from findings they disagree with. It does not predict inspection outcomes and is not affiliated with or endorsed by Ofsted. It is there so the story your evidence tells is one you already know, told in your own words.

Frequently asked questions

How much notice do schools get before an Ofsted inspection? Very little. Ofsted usually telephones between 9.30am and 10am on the Monday of the inspection week, with the inspection itself typically starting the next day. A confirmation email follows the call with a document list and questionnaire links.

Do we need a written self-evaluation form for Ofsted? No. Ofsted does not require a self-evaluation form or any set format, and has said leaders will not be at a disadvantage if they do not have a written self-evaluation. What matters is that leaders can speak to their evidence with confidence.

What is the highest grade a school can get under the report card system? Exceptional is the highest grade on the five-point scale, followed by strong standard, expected standard, needs attention and urgent improvement. Grades are given per evaluation area rather than as one overall word for the school, and safeguarding is reported separately as met or not met.

How long after the inspection do we get the final report? A draft report usually arrives within 18 working days of the end of the inspection, leaders then have five working days to respond, and the final report is normally issued within 30 working days and published within 38 working days.

What is a deep dive in an Ofsted inspection? "Deep dive" is the name leaders still use for an inspector's close look at one subject. Ofsted's September 2026 operating guide no longer uses the term: inspectors agree curriculum areas of focus with leaders during the planning call, then explore them through extended learning walks and a focused conversation with subject and senior leaders. Our deep dive questions guide covers how to prepare.

Can we challenge factual errors in the draft report? Yes. Within five working days of receiving the draft report, leaders can raise minor points about factual accuracy or clarity, or submit a formal complaint about the inspection, though current guidance does not normally allow both routes to be used one after the other for the same report.

How is a multi-academy trust involved in an individual school's inspection? Ofsted currently inspects academies individually rather than trusts as a whole, though full inspection of trusts has been proposed for a later date. In the meantime, central teams are often present on inspection day to give context on the support provided and to help signpost inspectors to the school's current position.
