Ofsted uses four overall grade categories to describe how well a school is performing: Outstanding, Good, Requires Improvement, and Inadequate. Each grade carries different implications — from inspection frequency to government intervention. Understanding what the categories mean helps you make sense of your child's school's inspection report.
What are the four Ofsted grade categories?
| Grade | Meaning | Typical re-inspection interval |
|---|---|---|
| Outstanding (Grade 1) | Exceptionally high standards across all areas; the school is a model of best practice | Not routinely inspected unless concerns arise |
| Good (Grade 2) | Pupils achieve well, quality of education is strong, leadership is effective | Approximately every 4–5 years |
| Requires Improvement (Grade 3) | Below the standard of Good in one or more areas; school is not yet meeting expectations | Within 30 months, sometimes sooner |
| Inadequate (Grade 4) | Serious weaknesses or in Special Measures; may involve safeguarding failures or systemic failure | Monitored and re-inspected regularly — at least termly |
A school cannot jump from Inadequate to Outstanding in a single inspection cycle; Ofsted expects to see sustained improvement.
What is an "Outstanding" school?
An Outstanding school is one where Ofsted judges the quality of education, behaviour and attitudes, personal development, and leadership and management to be of the highest standard. Inspectors look for evidence that the school's curriculum is ambitious, that teaching consistently challenges pupils, and that virtually all pupils make excellent progress.
Since 2023, outstanding schools that have not been inspected for several years have returned to routine inspection. This has led to some previously Outstanding schools being graded Good or Requires Improvement — not necessarily because the school has declined, but because inspection frameworks have become more rigorous.
What does "Good" mean in practice?
The majority of schools in England are rated Good. It means pupils receive a sound education, safeguarding is effective, and leadership is purposeful. A Good school does not need to be perfect in every respect — inspectors will note areas to develop — but the overall picture is one of a school that is meeting its pupils' needs effectively.
When choosing between schools, do not dismiss a Good school in favour of an Outstanding one without reading both inspection reports carefully. An Outstanding report from several years ago may reflect a snapshot of a school that has since changed significantly.
What happens when a school "Requires Improvement"?
A Requires Improvement (RI) grade is a formal warning that the school must improve within a defined period. The consequences include:
- A follow-up inspection, usually within 30 months, to check progress
- Additional scrutiny from the regional Schools Commissioner or multi-academy trust
- In some cases, a package of support from a stronger local school or a National Leader of Education
- The school cannot be judged Outstanding at the next inspection — it can only move to Good
For parents, a Requires Improvement grade is worth reading carefully. Often the weaknesses are in specific areas — curriculum planning, for example, or sixth-form outcomes — rather than in everyday classroom teaching. Look at which sub-grades contributed to the overall grade before deciding how concerned to be.
What is "Inadequate" and what is Special Measures?
An Inadequate grade has two sub-categories:
Serious Weaknesses — the school is failing to provide an acceptable standard of education or has significant safeguarding concerns, but the leadership is judged capable of putting things right without external direction. The school is closely monitored but retains its existing leadership team.
Special Measures — the most serious category. The school is failing to give its pupils an acceptable standard of education AND the leadership is not demonstrating the capacity to improve without outside help. Special Measures triggers the most intensive intervention:
- Monitoring visits at least once a term
- A sponsor academy trust may be assigned to take over the school's running
- The regional Schools Commissioner can direct changes to leadership and governance
- Parents and the local authority are informed
Schools in Special Measures are typically re-inspected within 18 months. If there is insufficient improvement, further intervention — including forced academisation — can follow.
Do sub-grades matter as much as the overall grade?
Yes. Ofsted inspects four areas separately, and a school can score differently across them:
- Quality of education — the curriculum, teaching, assessment, and outcomes
- Behaviour and attitudes — pupil conduct, attendance, and culture
- Personal development — wider enrichment, character, and wellbeing
- Leadership and management — vision, governance, and safeguarding
A school graded Good overall might have Outstanding personal development and Requires Improvement for leadership — a mixed picture. Reading the sub-grades helps you understand specifically what is strong and what is being worked on.
What should parents do with this information?
- Read the full report, not just the headline grade, at reports.ofsted.gov.uk
- Check the date — an inspection from four or more years ago may not reflect the school today
- Look at what has changed — if a school has moved from RI to Good, that trajectory is significant
- Ask the headteacher — schools are required to publish their Ofsted report on their website and should be willing to discuss it openly with parents
Frequently asked questions
Can a school change its Ofsted grade between inspections?
A school's published grade remains on record until its next inspection. However, if Ofsted receives significant concerns — through anonymous tip-offs, whistleblowing, or local authority referrals — an unannounced monitoring visit or a full re-inspection can happen outside the normal cycle. Ofsted can also carry out Section 8 monitoring inspections of Good and Outstanding schools without changing the grade.
Does an Outstanding grade guarantee the best education for my child?
Not automatically. Outstanding reflects the inspectors' view at a point in time based on specific evidence. School leadership, staffing and culture can change significantly between inspections. Always visit the school, attend open evenings, and speak to other parents in addition to reading the Ofsted report.
What is a Section 5 vs Section 8 inspection?
A Section 5 inspection is a full inspection that results in an overall grade and published report. A Section 8 inspection is a shorter, focused visit — used to monitor schools between full inspections. Section 8 visits may lead to a full Section 5 inspection if concerns are identified, or they may simply confirm that a previously graded school continues to perform as expected.
How do I find my child's school's Ofsted report?
Ofsted publishes all inspection reports at reports.ofsted.gov.uk. You can search by school name, postcode or unique reference number (URN). Reports include the overall grade, sub-grades, key findings, and any actions the school must take before the next inspection.
