ADT College was established in 1991 as a City Technology College, funded by donations from various organisations including ADT Security Services (whose owner at the time was Baron Michael Ashcroft), Unisys, British Gas and Young's (who sponsored the schools "music bunker"). In 2007, the school was converted into an academy and renamed Ashcroft Technology Academy after its main private benefactor. Preceding this period the Building was the site of Mayfield School, an all-girl's comprehensive.
Ashcroft Technology Academy's latest Ofsted report, from 2015, gave a result of "Outstanding".
Teacher's contracts controversy
In 2011, the Academy was criticised after it was revealed that teachers' contracts contained a clause forbidding them from taking industrial action, despite such a clause being legally unenforceable in the UK. This was in addition to union negotiation rights not being recognised by academy leaders or governors. As a result, teachers belonging to the National Union of Teachers did not take part in strikes in June 2011 due to disciplinary concerns. The contract was called "draconian" by the Times Educational Supplement.
