The Tower School in Epping High Street opened on April 21 following a positive Ofsted pre-registration inspection.
The independent school, which provides education for young people aged 11-18 years who have autism and associated conditions, was visited by the education watchdog in March.
Inspectors reported The Tower School was ‘likely to meet all the independent school standards when it opens’.
The school is run by Acorn Care and Education, which is part of the Outcomes First Group, which has experience operating another 42 independent schools across the country.
The school will provide six lessons every day, with pupils receiving more than 25 hours of on-site education each week in 10 classrooms all of which are said to be “suitably resourced” to teach groups of up to seven pupils.
