In all of my interviews, I only saw one standardized test and that was at International House. There were a few short-answer classroom management questions and then I was asked to prepare a written lesson plan for a particular grammar point which was given to me. The other job interviews were basically the same but just done orally during the interview.
Honestly, I don't think such a test exists because there isn't just one correct way to do things in a classroom. Yes, there are many mistakes that should be avoided but different people will have different solutions to the problems they face and different people are suited to different classroom styles.
Are you looking to become a teacher and you want to prepare for your interviews or are you looking to hire some teachers and you want to know the latest techniques to look for?
