If you are already working as an unqualified teacher you may wish to pursue an Assessment only route into gaining Qualified Teacher Status (QTS)
Assessment Only route
If you’re an experienced teacher with a degree, you can achieve qualified teacher status (QTS) without having to do any further training. Assessment Only allows you to demonstrate that you already meet all of the standards for QTS.
To achieve QTS via the AO route, you’ll need to present detailed evidence that you meet the standards. Your teaching will be assessed in a school by an accredited and approved AO provider. You’ll also need to take the professional skills test in literacy and numeracy before you can be accepted onto the route.
This way of achieving QTS is only available to unqualified teachers who have taught in at least two schools, early years and/or further education settings.
A number of universities, colleges, schools and SCITTs around the country offer AO. Their criteria for entry may vary, and you will need to apply to them directly if you are interested in this route to QTS. You can register with the DfE for more information and help with the application process. Find more information on GOV.UK.
