You cannot apply for STO (between April and August Y12 or equivalent) if you already applied to another Sutton Trust programme, even if your previous application was unsuccessful. This is because all eligible students will already have been invited to STO. If you were not invited, this means you are unfortunately not eligible for the programme.
If you previously started an application to another programme, but did not submit it, then you are welcome to apply to STO.
You can read more about STO's eligibility on our website.
