Cambridge's pre-registration assessments (excluding LNAT)

The BMAT, ENGAA, NSAA and TMUA are organised by Cambridge Assessment Admissions Testing (CAAT) and are taken at a local authorised assessment centre, usually in early November. Dates have not yet been confirmed for 2022 but details will be published here as soon as they are available. 

For most UK students, the assessment centre will be your school or college. Check if you’re unsure, as you may need to find an open authorised centre instead. You should do this as early as possible in case your preferred centre is full. Open centres may also set an earlier deadline and it's your responsibility to check if this applies at your centre.

In most cases, your assessment centre will register you for the assessment - you can't register yourself. You must be registered by the relevant deadline (TBC) or you won't be able to take the assessment and your application to the University of Cambridge will not be valid. Please note, if you require access arrangements you must be registered earlier.

You'll need to provide the following information to your assessment centre in good time to ensure you can be registered:

  • UCAS Personal ID
  • name as it will appear on your UCAS application
  • gender
  • date of birth
  • details of any access requirements/arrangements
  • the university/institution (and Cambridge College or open application) you’re applying to
  • the course (including the UCAS course code) you're applying for

See the CAAT website for further information.


For Law, you're required to take the LNAT, which has earlier deadlines and different arrangements to other Cambridge pre-registration assessments.

For 2023 entry, you must take the LNAT by no later than 15 October 2022.  You can register for the LNAT from 1 August to 15 September 2022, and the LNAT can be taken from 1 September 2022. 

There is an extended deadline for mature applicants applying for Law to either Hughes Hall or St Edmund’s as part of the second application round and these applicants must take the LNAT by no later than 1 March 2023.

The assessment can be taken at any LNAT test centre – there’s over 500 test centres around the world with 150 in the UK.

Further information and details about how to register can be found on the LNAT website.

Does it cost anything to take a pre-registration assessment?

There's an entry fee for students to take the BMAT, LNAT and TMUA. Please check the assessment website for details and advice. If you're a Home fees status student who's concerned about the cost, financial support may be available.

You don't have to pay an entry fee for any of the other pre-registration assessments for Cambridge. However, please be aware that some assessment centres (including some schools/colleges) may charge candidates their own fee to cover administrative costs. Cambridge has no control over this charge.
