The Behavior Therapy Training Institute (BTTI) is an in-depth three-day (or five-day, if held virtually) intensive training course in exposure and response prevention therapy (ERP), a form of cognitive behavior therapy (CBT), for mental health professionals who are treating individuals with obsessive compulsive disorder (OCD) and related disorders. Led by a world-renowned faculty, the BTTI was developed to help address the shortage of therapists properly trained in using CBT to treat OCD around the country and the world.
In addition to the flagship General BTTI and our Pediatric-focused BTTIs, the IOCDF annually hosts the BTTI for Treating OCD in Communities of Color, a training for BIPOC clinicians and taught by BIPOC faculty, and the BTTI Virtual en Español, conducted entirely in Spanish.
For more information, review the Frequently Asked Questions (FAQ) at the bottom of this page.
Invitations to attend a BTTI in 2027 will be sent out in mid-November 2026.

Upcoming 2026 BTTI Sessions
Invitations have been sent for the remaining 2026 BTTIs.

How to Register
Clinicians who have filled out our BTTI Interest List get the first opportunity to register. Unsure if you're on the waitlist? Email training@iocdf.org to find out!
Registration for the BTTI is on a first-come, first-served basis once invitations are extended. Offers to register will begin being sent out in the order of individuals who completed the BTTI Interest List Form.
If a clinician is not able to attend the BTTIs offered, they will continue to be offered a seat for future BTTIs until they are able to attend. Offers will be extended to the next clinicians on the list until all seats have been filled.
Please note the following:
- Clinicians can only take either the General BTTI or the Pediatric BTTI, not both. If you work with youth at all in your practice (even if they are not your primary or sole focus), we highly recommend you opt to attend the Pediatric BTTI.
- If a clinician has filled out the BTTI Interest List multiple times, the IOCDF will use their earliest submission date to mark their place in line on the BTTI Waitlist.

Interested in additional advanced training?
The Advanced Forum is an opportunity for mental health professionals who have attended a Behavior Therapy Training Institute (BTTI) or a similar level of training to enhance their clinical skills. Each Advanced Forum focuses on a specific topic of interest to deepen the practice of clinicians who are comfortable treating OCD and related disorders.
