Haringey Council and Highgate Wood School say they welcome the inquiry into a paedophile case.
Former PE teacher Andrew Adam was jailed earlier this month for abusing a pupil in the 1980s.
The Local Safeguarding Children Board announced it would stage an independent inquiry to examine the school and council’s handling of the case.
In a joint statement, the school and council said: "The offences first came to light several years after Mr Adams' retirement from teaching and some time after any ongoing involvement he had with the school had ended.
"Given the very serious nature of the concerns raised by this case, the independent Chair of the Haringey Local Safeguarding Children's Board is going to review how the case has been handled since the allegations were received.
"Both the school and the council very much welcome this."
