Figures from the Department of Education and Children show every secondary school on the Island except one has seen falling pupil numbers this year.
Minister Graham Cregeen was asked a question for written reply about pupils in the House of Keys this week by Garff MHK Daphne Caine.
He said the only secondary school not to see a drop in numbers is Ballakermeen High, which is expected to get another 58 pupils this year.
That will take its projected roll to 1,558 - the school has a permanent capacity of just 1,370.
