Certificate
Certificate in Sex Therapy
Support Clients Across All Identities & Relationships

Antioch University’s Sexuality Studies Certificate Program is now housed in the Relational Therapy Division within the Couple and Family Therapy Program and, beginning in the fall semester of 2025, will include three tracks: 1) sex therapy, 2) sexuality education, and 3) gender-affirming clinical practice.
The mission of the Couple and Family Therapy program, and relatedly the Relational Therapy Division, is to prepare and train knowledgeable, skilled, self-aware, and ethical clinicians through an experiential educational approach that centers anti-racism, multicultural awareness, and social justice. The program has five goals and related student learning outcomes, focused on the areas of knowledge, practice, ethics, research, and diversity.
Our Antioch University certificate program is one of only a handful of accredited higher learning institutions in the United States, and the only one in Washington state, that is an approved provider of American Association of Sexuality Educators, Counselors, and Therapists (AASECT) education credit requirements. Students receive up to 180 hours of CEUs during the course of the program. The two tracks within this certificate program that currently meet the minimum education credit requirements for AASECT certification are the sex therapy and sexuality education tracks (provider ID# 18-123-AU).
This program is NOT designed to lead to state licensure. This low-residency certificate is offered by Antioch University's Seattle campus.
Sex Therapy Program Overview
The sex therapy track within the Sexuality Studies Certificate has been designed for students, alumni, and community members who hold a license to practice therapy in their respective state, or who are license-eligible, to broaden their clinical skills in sex therapy. It has been developed for graduate students and post-graduate professionals to meet the minimum education credit requirements to achieve certification as a sex therapist, as issued by the AASECT. This program is NOT designed to lead to state licensure. Completion of this program does not ensure or guarantee AASECT Certification. For further information, please contact [email protected].

Additional Program Information
Sex Therapy is a growing specialization in the fields of family therapy, mental health counseling, and clinical psychology. Qualified sex therapists work with a diverse range of issues including, but not limited to: sexual functioning, intimacy, sexual trauma, and gender, sexual, erotic, and relational diversity (GSERD). Sex therapy supports clients in accepting their sexuality and encourages a holistic lens to sexual health. Sex therapists work with a variety of clients, including those who identify with minoritized backgrounds, identities, and/or experiences in the GSERD matrix to those who may want to support their children in developing into sexually healthy adults and to those who desire improving intimacy within their partnership(s). The sex therapy certificate program approaches sexual health and wellness from a biopsychosocialspiritual approach to mental, relational, and systemic health and trains clinicians to be trauma-informed and GSERD-affirming. Graduates of the sex therapy certificate program serve a range of clients from many intersections of identities, backgrounds, and experiences.
Current Antioch University students can work with their assigned advisor to create a plan of study that works with their professional goals.
In general, the course load is reasonable and standard for graduate-level training in terms of reading and writing. The classes are highly experiential and require ongoing awareness of self-of-the-therapist issues and, in some of the classes, to demonstrate active learning and application of the techniques.
