Whitehorse Manor Junior School is a junior school for pupils aged between seven and eleven years. The school is in Thornton Heath. In April 2011 the school became part of the first Academy Trust in Croydon and the running of the school became part of the responsibility of the Pegasus Academy Trust, a public company limited by guarantee. The executive headteachers of the Pegasus Academy Trust are Jolyon Roberts and Lynne Sampson. The head of school is Nina Achenbach.

The school caters for pupils from Year 3 to Year 6. The school is expanding the number of forms on entry from two to three. There are currently 450 pupils on roll with a maximum of 30 pupils in each of 15 classes. To cater for these extra children, a major building project took place between 2010 and 2014 providing seven extra classrooms, new offices, extended hall and library. The scheme was designed by the architects Hayhurst and Co and won a RIBA London award in May 2014. In 2014 the school opened an annexe about two-thirds of a mile (1.1 km) away, Whitehorse Manor - Brigstock site, which allows another 210 children to be educated by the school, as the original site is full.

The school was opened in 1892 and has a complicated history - having undergone a great many re-organisations. Dr Ron Cox, a consultant archivist to the Education Department of the London Borough of Croydon, lists the chronological story as follows:

• 1892-1911
  Three schools (apart from the infants) opened on the Whitehorse Road site: Whitehorse Road Junior (Mixed) school, Whitehorse Road Senior boys' school, Whitehorse Road Senior girls' school.
• 1911-1930
  In 1911 Whitehorse Road Junior (Mixed) school closed and the pupils moved into the respective boys and girls departments of the two senior schools, therefore, giving Whitehorse Road (Post-Infants) boys' school and

Whitehorse Road (Post-Infants) girls' school.

• In 1921 as part of a general re-organisation of school names the Whitehorse Road schools were re-designated "Whitehorse Manor".
• 1930-1955
  In 1930 there was a substantial re-organisation. All the Whitehorse Manor senior girls moved to another local school, Ecclesbourne, and all the Ecclesbourne senior boys moved to Whitehorse Manor. All the Whitehorse Manor junior boys moved to Ecclesbourne and all the Ecclesbourne junior girls moved to Whitehorse Manor. On the Whitehorse Manor site, this left Whitehorse Manor Senior (later secondary modern) boys' school and Whitehorse Manor Junior girls' school.
• 1955-1961
  In 1955, the headmaster of the boys school during this period was Mr Pavey who had returned from retirement.
• 1961 to 2011
  in 1961 both the boys and girls school amalgamated and have been mixed ever since
• From April 2011
  The school became part of the Pegasus Academy Trust.

Agnes Mason, an associate of D. H. Lawrence, taught at this school for some years until Davidson Road School opened in 1907 when she went there to teach with Lawrence. A description of the school and its staff at that time is to be found in Helen Corke's book In our infancy:an autobiography, Part 1 1882-1912. She too was an associate of Lawrence.
