Jonathan Grant High School was named after the late parliamentarian, The Honourable Jonathan Grant, who was the Minister of Labour in 1957, in recognition of his invaluable service in Spanish Town.
On October 6, 1980, Jonathan Grant Secondary School opened its doors to six hundred and thirty students. The school was first advertised as Spanish Town Secondary 2, but later became Jonathan Grant Secondary School.
With Mr. Courtney Brown as Principal, and Mrs. Myrtle Parkes as Vice Principal, along with eighteen teachers, the stage was set for educating the eager students. Students were selected from pimary and all age schools in the Spanish Town environs, and even as far as Point Hill, Kitson Town and Sligoville.
The school started with fourteen classes, grades (71 to 714) and offered courses in the academic and practical subjects - Agriculture, Industrial Arts, Home Economics, and Art & Craft.
As the years went by, the school population grew, so in 1984 the shift system was introduced and Mrs. Cortis Nolan became the second Vice Principal. Other Vice Principals that served were Mr. Alfred Ives, Mr. Solvalyn Eccles, Mr. Noel Cameron, Mrs. Beryl Cameron, Mrs. Edith Forbes, Mr. Leslie Mair, and Mrs. Welzoline Alleyne. Today, the school is administered by the following: Mrs. Cortis Nolan (Principal), Mrs. Beryl Cameron (Vice Principal), Mr. Garret Bucknor (Vice Principal), Miss Cheryll Shippey (Vice Pricipal) and Mrs. Mary Frank (Vice Principal).
The first set of graduates left the intstitution in July 1985. They sat examinations in Secondary School Certificate (SSC), ULCI, and the CXC.
The school suffered much from the 'stigma' attached to the Junior Secondary Schools. However, we soon overcame these challenges as our CXC results coupled with our outstanding performance in cricket and football outshone the performance of many traditional high schools.
Jonathan Grant High School has grown over the years. The population of the school grew from 637 students in 1980 to 2,450 in 2005. There are 103 members of the academic staff including 2 Guidance Counselors and 3 Vice-Principals.
