IFS Trained, Certified, Informed
Four words people put next to “IFS” on a bio, only two of which anyone controls.
Description
Trained means you sat through a training. The IFS Institute runs Level 1, Level 2 and Level 3 programmes, and finishing one is a real thing — Level 1 in particular is long, expensive and hard to get a place on. It is not a credential. “Level 2 trained” says what you attended, not what anyone has assessed.
Certified is the assessed thing, and it is separate. You apply after Level 1, and the Institute asks for roughly two years and two hundred hours of applying the model in your professional field, continuing education, hours of consultation with an approved consultant, and a session review — recorded or live — that someone actually watches. There are two designations. Certified IFS Therapist requires a mental-health degree and a current clinical licence. Certified IFS Practitioner requires that you be registered or certified in whatever your own field is, which is the door through which coaches, bodyworkers and other non-clinicians come in. Both are the Institute’s to grant and to withhold, and only certified people may use those exact titles.
IFS-informed is the honest word for everyone else, and nobody controls it. It usually means: trained to some level, or trained elsewhere, or self-taught, or a long-standing client, and now bringing the model into work that isn’t IFS therapy. It can describe someone with a decade of practice and it can describe someone who read No Bad Parts on a plane. This is why the first question on our resources page is what training have you completed, and with whom.
Therapist, unlike the other three, is regulated by the state you are in and not by anyone in IFS.
The part nobody puts on a bio
There is no settled legal owner of the words “Internal Family Systems”. The Institute’s parent company registered IFS INTERNAL FAMILY SYSTEMS in 2012 and let the registration lapse in 2022. It filed again in August 2023 — for IFS, IFS INSTITUTE and INTERNAL FAMILY SYSTEMS — and as of 2026 none of the three has registered: they are under opposition at the trademark office, suspended while a federal lawsuit runs. That lawsuit is the Institute suing PESI, Evergreen and one of its own lead trainers over a competing “IFS” certification. In April 2026 the court let the trademark claims proceed but explicitly declined to decide whether the marks are protectable at all; the defence is that “internal family systems” is simply the name of a method, the way Pilates and several martial arts turned out to be. That question is open.
Meanwhile the Institute has been tightening who may train, and in 2024 a move toward restricting Level 1 to licensed mental-health practitioners produced a petition with several hundred signatures from people it would have shut out, clinicians included. The vocabulary fights and the access fights are the same fight.
What this is NOT:
Not a ranking. A Certified Practitioner is not a junior Certified Therapist, and neither is automatically better for you than someone IFS-informed who has been doing this for fifteen years. Not a safety guarantee either — certification checks competence with the model, not fit with you. And not a reason to be rude to people about their titles: most practitioners describe themselves accurately, and the confusion is in the system rather than in them.
Examples:
“Level 2 trained, IFS-informed coach” — accurate, and tells you they are not certified.
”Certified IFS Practitioner” — the Institute has assessed them; they are probably not a licensed therapist.
”IFS therapist” with no other detail — worth one polite question.
