Teachers could have lessons covered by volunteers from the Women's Institute under plans to cut teacher workload.
Heads attending a training session in the Wirral to discuss the new workforce deal were told that WI members could be called in to give teachers more time for planning.
A spokeswoman for the National Remodelling Team, which is overseeing the deal, said the idea was for discussion only. "It is up to each school to decide what works best for them," she said.
Heads and teachers' unions have dismissed the idea, and said that not enough volunteers would be available.
