The school was given approval for opening in February 2017 by the Department for Education, and opened in September 2017 in temporary accommodation on the site of
St Clement Danes School. The old maths block of the school was refurbished to provide separate facilities for the Croxley Danes students, with 120 new
year 7 pupils admitted in the first year. In September 2018, a further 180 students were admitted and the school moved to temporary accommodation in Tolpits Lane, occupying the former site of the Reach Free School, whilst the permanent site was being completed. This move was carried out instead of building temporary buildings on the permanent site to accommodate the students. The transfer of the school to the permanent site on Baldwins Lane was planned to take place at the end of the Easter term in 2020, but delays meant that the transfer instead occurred over the school summer holidays, with pupils first attending the new site in September 2020. == Houses ==
