An appeal for Welsh-speaking teachers in England to return to work in Wales is one way schools have responded to concerns about recruitment.
Politicians have warned plans for a million Welsh speakers by 2050 will fail without a big increase in staff.
The Welsh government said it was taking action, including financial incentives and grants, to help schools recruit.
One group of schools got a grant to hold an online jobs fair for Welsh-speaking teachers over the border.
Trystan Edwards, head of Ysgol Garth Olwg in Church Village, Rhondda Cynon Taf, who is chairman of the group said it was important to be positive and innovative in the face of the challenge.
"The hope is to build on the success of the initiative by holding similar events in the future," he said.
