Become a health apps assessor

We need qualified assessors to help us publish high-quality products on the NHS Apps Library.

Benefits of becoming an assessor

We want to appoint approved assessors to carry out assessments, to bring more trusted apps and digital tools to the NHS Apps Library.

Being an assessor will allow you to:

  • raise the profile of your organisation
  • develop expert knowledge of the standards digital health solutions must meet
  • provide expert advice to anyone building a product
  • advise commissioners on the assessment standards that products should meet
  • help increase the number of trusted products on the NHS Apps Library, to empower patients and the public to take better control of their healthcare

We plan to:

  • design an approved assessor badge, to show that an organisation is authorised to carry out assessments on behalf of NHS Digital
  • offer a list of approved assessors, for developers to choose an organisation to help them through our assessment process
