Become a qualified teacher with our QTS Assessment Only route

If you are an unqualified teacher with a degree and significant teaching experience you can achieve qualified teacher status (QTS*) in as little as one term through our Assessment Only (AO) course. Gaining QTS via this route will allow you to become a qualified teacher without leaving your school and will also demonstrate that your teaching meets the Teachers’ Standards.

This QTS qualification will allow you to take the next step in your career as a teacher and it could help you increase your earning potential by up to £7,000**.

Who is suitable for our Assessment Only route?

Your teaching experience should have occurred in at least two schools and across two consecutive age ranges, giving you the opportunity to gather significant evidence to show that you meet the QTS Teachers’ Standards.
