Owen Speid, President of the Jamaica Teachers' Association
There was heightened security at Vauxhall High School in East Kingston on Monday following the killing of a teacher on the compound on Saturday.
Police personnel were seen at the Windward Road-based institution.
Carl Samuels, 36, was closing the gate of the school after working on students' report cards when he was attacked.
The teacher, who was a licensed firearm holder, managed to kill one of his attackers, an 18 year old boy.
Jamaica Teachers Association President Owen Speid, who visited Vauxhall High on Monday, said while more police officers have been deployed to the school following the incident, long term measures are needed to improve security at the institution.
Mr. Speid said the mood at the school was sombre as teachers, past students and the school community dressed in black and wept openly.
