Six modules. Dissociation mastery.
Theory of Structural Dissociation
ANP/EP model, Van der Hart & Nijenhuis — mapping dissociative organization across the spectrum.
Assessment & Differential Diagnosis
MID, DES-II, SCID-D, and clinical interviewing for DID, OSDD, and dissociative subtype PTSD.
Phase 1 Stabilization for Dissociation
Window of tolerance work, grounding, internal communication, and safety planning with parts.
Working with DID & OSDD
System mapping, alliance across parts, negotiating triggers, and pacing traumatic memory work.
Internal Family Systems for Trauma
Self-led healing, unburdening protectors and exiles, and IFS–SP integration for complex cases.
Integration, Supervision & Long-Arc Care
Fusion vs. cooperation, ethics, supervision skills, and a supervised capstone dissociative case.
Specialist depth
Built for the most complex cases
CPT-III is structured around the clinical realities of dissociative work — pacing, parts, assessment rigor, and long-arc planning — with the supervision infrastructure those cases require.
Parts-Work Clinics
Live small-group clinics practicing system mapping, parts negotiation, and Self-led facilitation.
Dissociation Assessment Toolkit
Structured guidance for the MID, DES-II, and SCID-D — with scoring, interpretation, and case examples.
Long-Arc Case Formulation
Frameworks for multi-year treatment planning across stabilization, processing, and integration.
Supervision Foundations
Prepares you to mentor CPT-I and CPT-II clinicians on complex dissociative presentations.
Certification pathway

Frequently asked
Answers before you enroll
Who are TPA certifications designed for?+
Our CPT track is built for licensed mental health clinicians and graduate students. TS-C is designed for allied professionals — educators, first responders, healthcare staff, and case managers — who need trauma-informed knowledge without crossing clinical boundaries.
Are TPA programs APA approved?+
Yes. TPA is an APA-approved sponsor of continuing education for psychologists, with additional recognition from NBCC, IACP, EMDR International, ISTSS, and alignment with WHO trauma care standards.
How long do certifications take to complete?+
CPT-I is a 40-hour program typically completed in 8–12 weeks. CPT-II runs 60 hours, CPT-III 80 hours, and PsyT is a 120-hour leadership track that most candidates complete across two to three semesters.
Is coursework live or self-paced?+
Every certification blends self-paced video modules with live cohort case consultations and supervised practice sessions. Live sessions are scheduled across multiple time zones.
What CE credits do I earn?+
Each program awards CE hours matching the contact hour total — 40 hours for CPT-I, 60 for CPT-II, 80 for CPT-III, 120 for PsyT, and 24 for TS-C. Credits are accepted by major licensing boards worldwide.
