Hiya I think there are quite a few options open tbh.
Level 4 seems to be a more indepth broader version of L3 .. the foundation degree is also a possibility along with the OU !
For family & social care / work
Socialworkercareers.co.uk has some great information as does the
Career options page from the Open University
You have to actually enter the DoH Social website before being able to verify who manages and regulates the content.
Have you thought about an interview with the Job centre's careers advisor & contacting EYs dept to see what funding is available ?
Let us know what you come across
