Supply teaching is very much a job in demand. For example, there will always be schools looking out for supply teachers when theirs fall ill. And with so many institutions in various towns, it can be relatively easy to pick up supply teaching jobs locally; while good performances may see you become a regular member of staff.
Supply teaching jobs are out there to be found and they can improve the variety of teaching skills you possess. One day you could be teaching at a primary school, then perhaps a secondary school. This can improve your own career and help it develop, yet it must be said that supply teaching is not just an option for inexperienced teachers.
If you’re thinking about cutting down your hours, perhaps approaching retirement, supply teaching can also be a good option. In effect, you can potentially do as you can do as much or as little work as you like.
Supply teaching also allows you to test out various schools, meaning you can have a better idea of the school you want to become a permanent teacher at. Some teach remain supply teachers throughout their career, and it because of the enormous demand, this is becoming a workable option.
