In the Grenada of 1962, Maurice Bishop graduated from Presentation Brothers' College. Nine months later Bishop left for Great Britain to study law. Bishop's most outwardly and public political activity, during his secondary school years and the months following graduation, he shared with his lifelong friend Bernard Coard. They were co-founders of the Grenada Assembly of Youth After Truth. This was an organization supplosedly formed to enable students of both Presentation College and Coard's Grenada Boys Secondary School to discuss events concerning Grenadians.
