Yes, internationally based mental health professionals can join the Certification Track and become a CGT.
Level 1, Level 2, Treating Affairs & Trauma, and Couples & Addiction Recovery are all available to take as an online course. Level 3 Training is available as either a virtual or in person live training. The Certification Track and consultation is available to complete entirely remotely as well.
For international based therapists, the main criteria is a license to practice psychotherapy independently in the country in which you practice. Typically, a graduate degree in a mental health field (psychology, psychiatry, psychiatric nursing, social work, counseling, marriage and family therapy) with a supervised clinical internship providing psychotherapy is required. Coursework must include psychological assessment, psychopathology (training to treat co-morbidities such as PTSD, mood disorders, depression, anxiety disorders, substance abuse, domestic violence).
Disciplines such as coaching, mediation, family life education, child development, and pastoral care typically do not meet the requirements for eligibility.
Additionally, you should be a registered, accredited member of your local association so long as the association is within the mental health field, you're able to practice therapy in your city of residence, and continuing/professional development is required.
