Where can I find secondary part - time jobs?

[Silversal]

Hello I'm a secondary school teacher looking to get back to work after a little while out of the system. I have a little one now so need something in either Herts/Bucks/London for 3 days a week if possible. Where do I start? Any agencies/job board suggestions would be most appreciated. Thank you

What subject are you? Most jobs are advertised on TES. You can always contact school to see if they will welcome applicants from part time - many will in the current recruitment crisis

TES is the best place to search for roles.

If your local school is part of an academy trust then roles are usually advertised on their website. You can also check the school website of schools near to you as they also generally have a vacancy page.
