The Isaiah Thomas Secondary School, located on the west central coast of Dominica came into being in the early 1980’s at which time it was referred to as the St.Joseph Campus of the Dominica Grammar School under the guidance of Principal Mrs. Jenifer Wallace Lafond.

In the early 90’s there was a name change to the institution making it now the St.Joseph Secondary School. The name was finally changed again to what is now the Isaiah Thomas Secondary School. This settled name took effect on June 15th1999 when it was named after one of the villages prominent sons, Isaiah Thomas. Mr. Thomas was a Lawyer and a Minister of government in the Labour Party government of the 1970’s.
