Best Secondary schools in Hertfordshire
These rankings cover secondary schools in the local authority of Hertfordshire based on the most recent graded Ofsted inspections. We order by headline grade first, then by publication date; ties are broken using “Quality of education” (where available), then contextual signals.

How we rank these schools
- Headline Ofsted grade orders: Outstanding (1), then Good (2), then RI (3), then Inadequate (4).
- More recent graded inspection dates rank higher.
- Where available, we use the Quality of education sub-judgement as a tie-breaker.
- We may consider contextual signals (e.g., %FSM, roll size) to break remaining ties.
Ungraded visits don’t replace the last graded judgement.
