Hiya, I had a SCITT interview for my PGCE course. We had to choose a book and read it to a small class of children, and then received feedback for this afterwards. We then had a presentation to give to the other interviewees which lasted 10 minutes. Then were our one-to-one interviews, and finally we had to do a Literacy test afterwards (if I recall it was a level 6 SATs test). I don't know how your interview will go, but the best advice is to come across as confident and interested. I was told during my one-to-one interview that they were impressed that during my presentation, I had mentionned the name of another potential candidate. When is your interview or have you already had it yet? Good luck either way! :)
