The Graduate Teacher Training Registry (GTTR) holds all the information about teacher training courses and is the website to use to make a PGCE application for the majority of Initial Teacher Training (ITT) providers. This is a great resource for all pedagogy studies.Through the GTTR you are able to apply to up to four different providers for secondary courses. If you are unsuccessful with your first choice, your application will be passed on to your second, and so on. It is a good idea to apply before the end of November in the year before you wish to train because there is often competition for places on certain courses.
