INSIDE ISI INSPECTIONS

Most schools meet the standards. The ones that don’t tend to stumble in the same places.

An independent analysis of 394 routine ISI inspection reports from the 2025-26 cycle. What gets praised, what gets penalised, and the dozen recurring issues behind almost every “not all met” outcome.

WHY IT MATTERS

Reading 394 reports tells you what is happening across the sector.

Preparing for inspection well is harder than it looks from outside. Most leaders work from a small sample: their own last report, a few from peer schools, and conversations with colleagues who have recently been through it.

ISI published 394 routine inspection reports between May 2025 and April 2026. Reading any single report tells you what happened to that school. Reading all 394 tells you what is happening across the sector.

This work turns the corpus into one usable synthesis:

  • what gets praised, and what gets penalised
  • the dozen recurring issues behind almost every “not all met” outcome
  • recommended next steps and action points, mapped by theme
  • the pedagogical patterns that recur across the cycle
  • the framing most likely to earn a “significant strength”

Step into your next inspection with the evidence of 394 schools behind you.

Inside ISI inspections · sector briefing
From September 2026, ISI reports no longer use the label significant strength.
We read the last 394 reports that did.
Each square is one inspection. 345 schools met every standard. The 49 dark squares, 1 in 8, did not.
46 of 49
schools with an unmet standard fell short on welfare or safeguarding.
4 on quality of education. 3 on leadership only. None on social and economic education.
129 of 177
action points sit in just five themes: attendance, policies, safeguarding records, health and safety, premises.
Action points appear only when standards fail. All 394 schools get recommended next steps. There were 722 of them.

IN CASE YOU WERE WONDERING

Frequently asked questions.

ISI’s review is the regulator’s account of its own activity, with aggregate figures against the eight statutory Parts. This report analyses routine inspections in detail, surfaces patterns the aggregates cannot show (52 schools told to improve careers, only one praised for it), and reads the corpus from a school leader’s perspective with discussion prompts and an audit checklist. ISI summarises. This is an analysis with insight and resources for school leaders.

Every routine ISI inspection report published between May and April in the 2025-26 inspection cycle. The corpus contains 394 reports. It excludes all other types of inspection (e.g. material change inspections).

The standard licence is for the purchasing school, trust or organisation, with SLT and governance access included. Multi-site licences for MATs and associations are available on request.
