MARS Medical Appraisal Revalidation System
MARS is an all-Wales system provided by Health Education & Improvement Wales and funded by Welsh Government to facilitate the appraisal and revalidation of doctors.
If you are new to MARS or new to Appraisal & Revalidation you can find useful information on our Revalidation Wales website.
If you are a GP please use GP MARS.
Did you know that Good Medical Practice (GMP) 2024 came into effect on 30th January 2024? The Revalidation Support Unit created a brief user guide to detail the updates on MARS that were implemented on 18th March 2025.
Further information can be obtained here - GMP-Changes-Doctor-User-Guide-2025-2.pdf
Please note, the types of supporting information you need to collect and reflect upon for appraisal and revalidation have not been changed.
The Service Desk for MARS and Orbit360 will be closed on the 29th April. E-mails will be checked intermittently throughout the day in case of anything urgent.
