“How long does it actually take?” is one of the first questions leaders ask. The honest answer has two parts: the on-site inspection is short — normally two days — but the full timeline, from the notification call to the published report card, stretches over several weeks. This guide sets out how long each stage lasts under the November 2025 framework, so schools can plan realistically.
Quick summary
- A routine inspection normally lasts 2 days on site.
- Smaller schools may be inspected over a shorter period.
- Notice is short: usually a phone call between 9:30 and 10am, shortly before the inspection.
- After the visit, the draft report card allows 5 working days for factual accuracy comments.
- The finalised report card is usually sent to the school within 18 working days of the inspection ending.
On-site: how long inspectors are in school
Under Ofsted’s inspection information for state-funded schools, a full inspection normally lasts 2 days.
There are variations:
- Smaller schools — for example, small primary or nursery settings — may be inspected over a shorter period, sometimes a single day.
- The size of the inspection team scales with the size of the school, so a large secondary may have several inspectors across the two days, while a small primary may have one or two.
- Monitoring inspections (for schools identified as needing improvement) are typically shorter and more focused than a full inspection.
The notice period
The on-site days are preceded by short notice. The lead inspector usually telephones the school between 9:30 and 10am, shortly before the inspection begins, and holds a planning call of up to 90 minutes the same day. In specific circumstances, Ofsted can inspect without notice.
This is why “how long does it last” is best answered as a timeline, not a single number: from the moment the phone rings, a school is in an inspection process that unfolds over days on site and weeks to publication.
The full inspection timeline
| Stage | Typical timing |
|---|---|
| Notification call | Usually 9:30–10am, shortly before inspection |
| Planning call | Same day, up to 90 minutes |
| On-site inspection | Normally 2 days (shorter for small schools) |
| Draft report card to school | After the inspection, for a 5-working-day factual accuracy check |
| Factual accuracy window | 5 working days |
| Finalised report card | Usually within 18 working days of the inspection ending |
| Publication | On Ofsted’s website after finalisation |
Why the on-site time is deliberately short
The framework was designed to be proportionate and to reduce workload. The removal of intensive subject deep dives, and a focus on the school’s context and priorities, keep the on-site burden contained. A short, focused inspection is intended to capture the school as it genuinely operates rather than as a prolonged event to be managed.
What this means for planning
- Don’t plan for a long event. The on-site inspection is short; the pressure is intensity, not duration.
- Plan for the timeline, not just the days. The report card takes weeks to finalise; manage internal and parent communications accordingly.
- Use the 5-day window deliberately. After the draft arrives, you have five working days to raise genuine factual inaccuracies.
- Stay continuously ready. With short notice and a two-day format, readiness must be a permanent state.

Frequently asked questions
How many days does an Ofsted inspection last?
A routine inspection normally lasts two days on site. Smaller schools may be inspected over a shorter period.
How much notice do schools get?
Short notice — usually a phone call between 9:30 and 10am shortly before the inspection, with a planning call the same day. Ofsted can also inspect without notice.
How long until the report is published?
The finalised report card is usually sent to the school within 18 working days of the inspection ending, then published on Ofsted’s website.
How long is the factual accuracy check?
Schools have 5 working days to comment on the factual accuracy and clarity of the draft report card.
Are monitoring inspections shorter?
Yes. Monitoring inspections for schools needing improvement are typically shorter and more focused than a full inspection.
Does the inspection team size vary?
Yes. The number of inspectors scales with the size and phase of the school.
Conclusion
An Ofsted inspection lasts, on site, about two days — but the process from notification to published report card runs over several weeks. Understanding both the short on-site window and the longer publication timeline lets schools plan calmly, communicate well, and keep their focus where it belongs: on the everyday quality inspectors come to see.
How AI Buddy supports schools
Because the on-site window is short and intense, schools benefit from being able to show learning and progress instantly rather than assembling evidence under pressure. AI Buddy is designed to support schools in strengthening areas evaluated during Ofsted inspections, giving teachers and leaders continuous, ready-to-hand insight into engagement, progress and learning gaps. It is not endorsed or certified by Ofsted; it is built to help schools stay inspection-ready year-round.
