The NSW government says teacher vacancy numbers in NSW public schools have fallen to a three-year low under their government as they work to address the teacher shortage.

New figures show that there were 24 % fewer vacancies at the start of Term 3 than the same time last year with data indicating resignations and retirements have dropped, as changes made by the Minns Labor Government stem the flow of teachers leaving NSW schools.

The government states at the height of the teacher shortage crisis under the former Coalition government, vacancies rose above 3,000 and resignations outstripped retirements for the first time.

Minister for Education and Early Learning Prue Car says the drop in resignations and retirements shows teachers are hearing that they value their work and are supporting them to focus on delivering quality teaching and learning.
