So you will probably have just spent years at university completing your teaching degree. When you qualify as a teacher you have the choice as to whether to go into a permanent position or to go in to supply teaching. Supply teachers can be very varied and you may find yourself in a different school or class every day or you may be offered a short term placement at one school. Supply teaching can be a very rewarding job and many teachers find it as rewarding as a permeant placement. If you have qualified as a teacher and looking for work quickly or if you have been employed as a full time teacher and are looking for something different then many people recommend trying supply teaching.
Supply teacher jobs can offer you the chance to gain experience working with children of all ages and backgrounds. As a supply teacher you will usually get paid more per day than a full time employed teacher would which means that you may only need to work 3 or 4 days a week to make your salary up to that of what you would have earned in a permanent position. But you need to bear in mind that you will not get paid for the school holidays. If you find your current teaching job stressful, supply teaching may be just the break you need allowing you to work with a variety of pupils and often not having to worry about the all aspects of planning, marking and assessments etc.
