Each pathway to certification relies on training, supervision, and clinical hours to build your confidence and knowledge around sex therapy and couples therapy. At ISTI we provide both AASECT and ISTI paths to certification, so how are they different?

The future of this field demands that clinical professionals integrate both sex therapy and relationship counseling in order to keep up with the challenges of contemporary practice. Integrative Sex and Couples Therapy is a new field of learning for all therapists that builds on sex therapy and relationship therapy and adds a third area: alternative forms of treatment designed to meet the contemporary needs of today’s clients.

AASECT certification emphasizes sex therapy in all of its programs. Our institute is an AASECT-approved provider and coursework through our institute, along with our professional guidance, helps you reach AASECT certification easily.

ISTI training is committed to the integration of couples/relationship therapy and sex therapy throughout our certification paths. Expert instructors provide new courses synchronously and hundreds of hours of eLearn courses to change the way we approach therapy today. Our commitment to guiding and supporting you along your chosen path is always the same regardless of the training you select.
