Estcourt High School was founded in 1924 from the upper forms of the Estcourt Government School when it was split into two.
Estcourt Government School After a number of attempts to establish private schools had failed due to lack of support, the town's first government school, the Estcourt Government School was established in 1886 with an initial role of 45 children. That year four children sat the matriculation exam. This sparked a growth in demand for secondary education and in 1927 the school was split into two - Estcourt Junior School retaining the old school building and the high school moving to a new 10 ha site.
AC Martin's headmastership Martin planned the new school as a co-educational school catering for both boarding and day pupils and by the end of his headmastership for both English and Afrikaans speaking pupils. During the first year of the school's existence on Hospital Hill, a hostel with 50 places was completed with a second hostel following in 1936. He was instrumental in the school having a
coat of arms designed by the
College of Heralds. The school site was split into two by the Loskop road. Martin laid out the school's academic and hostel accommodation to the north of the road and the sports fields, consisting of two full sized
cricket pitches, two
rugby pitches, and three
hockey pitches to the south of the road. He persuaded the Estcourt Town Council to donate a further 8 ha of land to the school enabling it to offer the study of agriculture to its pupils. A swimming pool was opened in 1931 - the first for any state school in the province. In 1934 Martin initiated the building of a separate science block, but it was not completed until 1941, by which time Martin had left the school. The block was named
Martin Block in his honour.
R O Pearse's headmastership The
Second World War broke out in 1939 and in 1940 Martin, was recalled to his regiment, the
Durban Light Infantry. Martin, along with many school old boys and parents of pupils was later to be taken as a
PoW at
Tobruk. Three months after Martin left the school, Reg Pearse took up the headmastership of the school. Once the war had finished, Pearse set about expanding the school. Almost immediately he set about overcome administrative obstacles and developing strong ties with both the farming and town communities to negotiating funds for the
Memorial Hall which was eventually opened in 1957.{{cite journal The school's sports teams played against other schools across the entire province. Due to government-imposed restrictions under the
Apartheid regime, the school was only permitted to field teams against other schools reserved for whites. As a result, the teams often had to travel 100 km for away matches.{{cite journal
Subsequent headmasterships Pearse retired at the end of 1965 and Mitchell Lindsay, the former deputy head who had joined the school in 1937, was appointed headmaster. Lindsay's wife, whom he married in 1943 was the former Jean Leiper, also a maths teacher, who served the school from 1937 until 1970.{{cite journal Until the end of the 1960s the school had been an academic high school; technical and commercial subjects being offered at other schools in the province, but none of which were in Estcourt itself. In December 1969 Lindsay announced the conversion of the school from an academic school to a comprehensive school with academic, technical, and commercial subjects being offered alongside each other in Std VII from 1971 progressing to the matric exams of December 1974.{{cite journal == The school coat of arms ==
