INSIDE ISI INSPECTIONS
Most schools meet the standards. The ones that don’t tend to stumble in the same places.
An independent analysis of 395 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 395 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 395 routine inspection reports between May 2025 and April 2026. Reading any single report tells you what happened to that school. Reading all 395 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 395 schools behind you.

THE FINDINGS
Eight findings from 395 inspections.
A handful of patterns kept surfacing across the corpus. These eight stood out most. A useful starting point if you are preparing for inspection or trying to read what ISI is currently rewarding across the sector. The full report is available below.

IN CASE YOU WERE WONDERING
Frequently asked questions.
How is this different from ISI's own Annual Review of Inspections?
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 (53 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.
What time period does the report cover?
Every routine ISI inspection report published between May and April in the 2025-26 inspection cycle. The corpus contains 395 reports. It excludes all other types of inspection (e.g. material change inspections).
Can I share the report within my school or trust?
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.
Will the analysis be updated each year?
Yes. Azimuth aims to publish an updated edition each year, with year-on-year tracking on key findings and other emerging themes.
