City and Guilds Functional Skills 2019 reform
City and Guilds have a very informative page about the upcoming Functional Skills reform.
This includes a useful downloadable mapping document for FS Mathematics (see image) from Entry Level 1 through to Level 2. The revised content is clearly mapped against the existing content and the adult numeracy curriculum. I believe documents about English are to follow shortly.
If you register you can join and attend live webinars about the reform (or you can catch up on these via YouTube - without registering).
