The course is accredited by several leading professional bodies with psychosexual and or relationship therapy registers: in particular COSRT and NCPS; we are also accredited with Middlesex University and an accredited pathway into the AR of the Prof Standards Authority (the only one in the UK).
Graduates are awarded 120 credits at Level 7 by Middlesex University, which allows progression onto a Masters Degree via the CAT system.

Successful completion of the two year London Diploma, followed by the one-year Advanced Diploma in Relationship Psychotherapy (www.naos-institute.com) fulfils all the criteria the Accredited Register of the Professional Standards Authority (PSA), via NCS.

2023 Update

LDPRT is delighted to announce that is has been re accredited with COSRT for another 5 years.
The assessor, who described the LDPRT as "prestigious training which continues to attract global students", commented in her report:

This is a long established and well-run course with a very experienced faculty. The care and commitment shown by the staff is impressive as is the ongoing development by the directors who work hard to increase the scope of their training.

And also that:

Students appreciated the richness and diversity of the group and the way that the course leaders emphasised that whatever their backgrounds and/or prior experience there was a level playing field on the training.

Masters Degrees

The London Diploma has been awarded 120 credits at Level 7 by Middlesex University. As part of an Accreditation of Prior Educational Learning (APEL) process, you may have these weighted at the university of your choice for on-going studies. You therefore have flexibility in your choice of where to take a Masters Degree, should you wish to do so.

Specifically at Middlesex University:

  • 80 of these 120 credits will be calculated to progress to a Masters programme
    (at the Work Based Learning & Interprofessional Learning, School of Health and Education)
  • The remaining 100 credits will be gained through the Middlesex University system:
    • 10 credits for a programme planning module
    • 30 credits for a compulsory research methods module
    • 60 credits for your final dissertation.
