Almost all schools in Tower Hamlets are good or outstanding, Ofsted figures show.
Out of the 100 schools inspected in the borough, 38 are rated outstanding and 59 good, as of October 31.
Ofsted, the schools regulator, inspects every new school within three years of being funded.
Inspectors judge education providers on the effectiveness of the leadership, quality of teaching and learning, personal development and welfare, and the outcomes for learners.
If a school is rated as inadequate it will be re-inspected within 15 months, and between one and two years if it requires improvement.
Out of the 17 secondary schools inspected in the borough, seven are rated outstanding, eight are classed as good and two require improvement.
No primary of secondary schools in the borough are inadequate, the lowest rating, and three require improvement.
Outstanding schools are exempt from routine inspections unless there is a specific concern about performance, however Ofsted said it would like to start inspecting them.
Across London, on average, 92pc of schools are good or outstanding.
