All Victorian state school zones are under review.

Every Victorian state school zone is being reviewed, with some boundaries set to be redrawn in a move likely to concern parents who have purchased expensive homes in sought-after enrolment catchments.

The changes will give principals greater powers to limit enrolments and are aimed at resolving ongoing confusion about school zones.

Victorian Education Minister James Merlino confirmed a review is under way, and said it would fix anomalies such as students being zoned to two schools or no school at all.

"For decades, schools and parents have found enrolment boundaries confusing and hard to find," he said.
