The Parkinson School was established by the Government of Barbados in 1961 as a Comprehensive Secondary School. It was officially opened by the then Minister of Education Mr Luther Thorne, as a co-educational institution. The first students were admitted by the feeder schools and later all students were allocated on the basis of the Common Entrance Examination. The school is named after Educator, Mr Rawle Parkinson.
Mr Barnett was the first Headmaster followed by Mr Husbands, Mr Bowen, Mr Reece, Miss Hunte, Mr Griffith and Mr Alleyne.
