Riddlesdown is a coeducational school, of 1902 students (311 of those being post–16 students). The school takes its pupils mainly from the Sanderstead, Selsdon, Purley, Kenley, New Addington and South Croydon areas, and specialises in science. Riddlesdown is the largest school in Croydon in terms of pupil numbers. In September 2009, the school's name changed from Riddlesdown High School to Riddlesdown Collegiate, featuring six colleges; four of which will hold a mixture of years 7–11, a Creative Performing Arts college and a Sixth Form college.
Four of the six colleges in the collegiate are 11–16 colleges with another for sixth form (16–19) and a Creative and Performing Arts College.

In an Ofsted inspection in 2009 the majority of the results were Grade 3 (broadly average or below average), with some Grade 2 (generally above average), compared with the previous 2005 inspection, which contained mostly Grade 2 results with some Grade 1 (exceptionally and consistently high) and few Grade 3.
In 1992, Riddlesdown was the first school in Croydon to be awarded Grant Maintained status by the Secretary of State for Education, and since then about 300 pupils have been admitted to the school by the Board of Governors each year.
