Staff across the region have started receiving letters notifying them of the impacts, but it is not yet clear whether any staff at the Dubbo campuses will be affected.

NSW Teachers Federation TAFE Western representative Terry Keeley said he received notification of the final plan on Wednesday.

"The signed off document was forwarded to me... and teachers and head teachers are now receiving letters in regards to whether they hold a job or not, or whether they are in competition with their colleagues to retain one of those positions," he said.

In a statement, TAFE Western Institute said "the changes announced will result in the creation of 18.5 new teaching positions to support delivery of training in high demand areas, and an overall net loss of 22.5 full-time equivalent positions".

It is not yet clear whether the 18.5 new teaching positions are full-time equivalent positions, nor the total number of staff who will be impacted by the changes.

In the statement, TAFE Western said it is committed to placing as many current teaching staff as possible in the new structure.

Earlier this year TAFE Western conducted a review in into its teaching workforce. The Building a Sustainable Workforce paper proposed cutting a total of 24 teaching positions, including 12 head teaching positions, from across the institute.

The paper had proposed cutting 57 full-time equivalent (FTE) head teaching positions to 45, 112.5 FTE teaching positions down to 103, and 24 FTE temporary positions to 21.5, Mr Keeley told the Daily Liberal at the time.

"This is the first time in more than 10 years that a full teaching workforce review has been undertaken," the statement from TAFE Western said.

"During this time there have been significant changes in skill needs across Western NSW.

"The review identified that whilst some full-time teaching positions are no longer required, other areas, including Community Services and Health, require additional capacity to meet increased demand."
