How to get your IDSR
- Sign in to Ofsted IDSR via DfE Sign-in (where you view your school's report).
- Open the full report for your school.
- Save the page: Ctrl+S → choose “Webpage, HTML Only” or “Webpage, Complete”.
- Drop the saved .html file above.
What you'll get
- Headline measures at a glance, colour-coded against national.
- Similar schools — the 2026 comparison, and where it disagrees with the national one.
- Three-year trend charts for achievement, attendance and behaviour.
- Strengths to celebrate — with the evidence to quote.
- Likely lines of enquiry, phrased the way an inspector would ask them, with preparation pointers.
Why this matters
- Inspectors read your IDSR before the initial call — it shapes their hypotheses.
- Knowing your own headlines, gaps and trends means no question lands cold.
- Print the analysis for SLT and governors as a pre-inspection briefing.
