These grades come from the system Ofsted replaced in November 2025. They stay on record until the school’s next inspection, when it gets a report card instead. More about the old grades.
Next inspection: around March 2027
The last inspection was in March 2023. Schools are usually inspected about every four years. That’s within the next six months.
An estimate, not an Ofsted date. Ofsted doesn’t publish its schedule and gives schools about a day’s notice. The law says the next inspection must be by August 2028 at the latest, and Ofsted can visit sooner if it has concerns.
