Ahmad Ibrahim Secondary School is a co-educational, secular, public school. The school is named posthumously after a patriotic Malay statesman, Encik Ahmad Bin Ibrahim, who was the first Minister for Health in independent Singapore. He also served as a Minister for Labour and was the Member of Parliament for the Sembawang ward.
The school was declared opened by Mr Lee Khoon Choy, Parliamentary Secretary, Minister of Education. AI adopted the motto of Tolerance and Cooperation as its aim was to break away from the language barriers that existed in most schools then. Mr Chia Meng An was appointed as the first Principal.
In 1967 the school was chosen as the first pilot school for Open Education Programme for the blind, whereby the visually challenged pupils were integrated into the main stream.
In 1985 the school moved to a new building in Yishun. It was the first school to function in that area.
