How many teachers are there in England and Wales?

There isn't a single, readily available, precise figure for the total number of teachers in England and Wales. Statistics are often broken down by type of school (primary, secondary, special), sector (state, independent), and even subject. You would need to consult government statistical releases from the Department for Education (England) and Welsh Government (Wales) and potentially combine data from multiple sources to get a close approximation. Searching their websites for "teacher statistics" is the best approach.
