ICST Inclusion Credentialing Process

The ICST Inclusion Credentialing Process (ICP) was designed as a method of inclusion within the International Crentialed Sandtray Therapist credentialing process to recognize qualifying individuals with core sandtray training. This recognition will provide an applicant the ability to apply to opt-out of the core levels of ICST training (levels one and two) and enter an advanced training cohort that will lead to ICST credentialing.

The International Association for Sandtray Therapy recognizes the investment of all sandtray therapists in their training and skill development. IAST is committed to increasing the number of credentialed sandtray therapists globally.
