Dubbo teachers will become the students in 2021 when individual courses to focus on classroom teaching improvement are implemented.
The NSW Government announced the quality of externally run professional development courses for teachers in NSW was under the microscope on Tuesday.
Minister for Education and Early Childhood Learning, Sarah Mitchell said the development will be done through best practice to receive NSW Education Standards Authority (NESA) accreditation.
"Currently, NESA only accredits providers of professional development and does not accredit individual courses," Ms Mitchell said.
"I have asked NESA to undertake an immediate review of their process for professional development provider accreditation and their courses.
"I want our teachers to be able to access the best professional development courses possible, providing them ongoing improvement."
There are 782 providers with over 42,000 active professional development courses as of June 23 2020.
The review will be completed by the end of 2020 with the new standards to apply from 2021.
