Presbyterian Boys' Senior High School

Presbyterian Boys' Secondary School (PRESEC) is a secondary boarding school for boys, in Legon, Accra, Ghana. It was founded in 1938, under the auspices of the Presbyterian Church of the Gold Coast.^[4] The Basel missionary-theologian, Nicholas Timothy Clerk (1862–1961), who served as the first Synod Clerk of the Presbyterian Church of the Gold Coast from 1918 to 1932, used his tenure to advocate for the establishment of the secondary school.^[4][5] The school has ties with its sister schools, Aburi Girls' Senior High School and Krobo Girls Senior High School.

The school's crest has a shield with the Presbyterian symbol (the St Andrew Cross-Scottish flag with the Swiss flag embedded and a burning torch in the middle) with the motto of the school, "In Lumine Tuo Videbimus Lumen", meaning "In Thy Light We Shall See Light", scrolled beneath the shield. The school was originally located in Odumase - Krobo in the Eastern Region of Ghana before moving to its current location in Legon, in 1968.^[4]

The school anthem is "Happy Are We", written by J. L. Anang and transcribed by Stephen Appiah Danquah.^[6] The school is a six-time Ghana National Science and Maths Quiz winner.^[7] The alumnus of the school are refereed to as "Ɔdadeɛ"
