Certification is a central concept at IfHI conferences. It allows consumers to make informed decisions about the qualifications of educators and  practitioners who wish to employ these modalities in clinical and teaching environments. Certification takes place at every IfHI Conference. All certification applicants must complete an examination that is administered at the conference. Certification is open to all applicants and does not require prior licensing or certification in any other healing art.  Upon certification, Fellows of the Institute have access to the extensive IfHI online resources (library and special members-only benefits).

Certification is available at two different levels:
