  • A completed course of training that satisfies the standards required by ARCH
  • Clinic premises that meet the standards set out by ARCH
  • A valid first aid certificate
  • A Disclosure & Barring Service check (formerly known as CRB check)
  • Registration with an independent voluntary regulator such as the CNHC.

The committee will also consider applications from practicing therapists who have trained at other schools if they can evidence and be verified that they meet the ARCH core curriculum and/or are prepared to undertake further study.

Types of ARCH membership

You can join the ARCH community at several different membership levels:

  • Full membership (for those members coming from a healthcare/CAM background) – giving you complete access to all member benefits.
  • Licentiate membership (for those members coming from a non-healthcare/CAM background) - giving you complete access to all member benefits.
  • Student membership – the first step for therapists who are registered for training with an ARCH recognised school.
  • Friend membership – aimed at members who no longer practice, but who want to stay in touch with ARCH and the industry.
  • Overseas membership – open to therapists who have trained at an ARCH recognised school and now practice exclusively overseas.

Full and Licentiate members are also obliged to register with a voluntary body on completion of membership to ARCH.
