A rate of about 80 to 100 per cent is considered ideal,and shows the school’s space is being used well. More than 100 per cent,however,indicates overuse.
Killara Public was one of the most over-utilised schools in 2018,but an upgrade has resulted in its rate dropping from 150 to 85 per cent. At Bourke Street Public,utilisation has dropped from 136 to 100 per cent due to an upgrade.
