What happens if my headteacher indicates that I am a 'cause for concern' once TIS has started?

If the headteacher at your allocated school indicated that you are a 'cause for concern' this will apply to both subjects due to the nature of the subject combinations offered. It is likely that it is your teaching experience and pedagogy that needs to be addressed. If you continue to be a 'cause for concern' the employer would not recommend the award for Full Registration at the end of the probationary period.
