Ego State Therapy (EST) is a psychodynamic approach that views the personality as composed of distinct "ego states"—relatively stable, organized systems of thoughts, feelings, and behaviors that exist within a single individual. Developed by Dr. John and Helen Watkins, EST was built on the foundational work of Paul Federn, a close associate of Freud. Unlike Freud's view of the ego as a monolithic entity, the Watkins conceptualized the personality as consisting of parts, or so-called ego states.
Ego states are not merely metaphorical constructs. They are understood as neurophysiological manifestations of the autonomic nervous system that develop in response to specific life experiences—both positive and negative. In the context of trauma, ego states may become "split off" to help the individual survive and cope, continuing to carry symptoms on an intra-psychic level.
Ego State Therapy addresses these symptoms by providing unique ways to understand the development of these states, access them, and restore physiological and psychological flow. The approach allows highly aroused survival energies—such as fight and flight responses bound up in traumatized individuals and dissociated ego states—to be discharged and completed, facilitating flow and post-traumatic growth. The goals include developing corrective mind-body experiences, renegotiating inner conflicts, and creating wholeness, self-regulation, and coherence.
The Training Landscape: What to Expect
Ego State Therapy training is typically offered through a combination of foundational workshops, intensive seminars, and supervised practice. Many programs are structured as a series of consecutive workshops that lead to certification. Training formats range from in-person intensives to online courses, and many programs integrate EST with other modalities such as EMDR, Somatic Experiencing, and hypnosis.
Core Learning Objectives
A comprehensive EST training program typically covers:
The neurophysiological basis of trauma, dissociation, and ego states
The dynamics of EST as a parts therapy model combined with hypno-somatic approaches
Hypno-somatic ego strengthening techniques for safety, stabilization, and grounding
Techniques from Somatic Experiencing, Trauma Therapeutic Yoga, and Energy Psychology
How to utilize client resources for maximum psychological well-being
Many programs also integrate contemporary theories including:
Interpersonal Neurobiology (Daniel Siegel)
Polyvagal Theory (Stephen Porges)
Somatic Experiencing (Peter Levine)
Structural Dissociation approaches
Certification Pathways
Ego State Therapy International (ESTI) Accreditation
A prominent certification pathway is offered through Ego State Therapy International (ESTI). Several training institutes offer workshops that form a series of consecutive sessions leading to internationally recognized certification as an ego state therapist with ESTI.
Training programs recognized by ESTI typically involve a phased approach, following models such as SARIA:
Safety and Stabilization
Accessing States
Reprocessing / Renurturing / Renegotiation
Integration of the Identity
Australian Institute of Clinical Hypnosis and Psychotherapy (AICHP)
AICHP offers comprehensive postgraduate training programs in Clinical Hypnosis and Ego State Therapy. Their 2025 offerings include:
Combined Postgraduate Intensives in Clinical Hypnosis and Ego State Therapy

Seminar 4 | 7-9 December 2026 | (Advanced topics) |
The seminars must be attended in consecutive order. Eligibility includes licensed psychologists, medical doctors, and individuals working in health-related fields.
Somatic Ego State Therapy (SEST) Training
A specialized pathway is offered through Somatic Ego State Therapy (SEST) , developed by Maggie Phillips, PhD. SEST combines Somatic Experiencing (SE) and Ego State Therapy into a holistic approach.
The 12-day training program (delivered in four 3-day modules) covers:
Principles and practices of EST and SE
Functions, roles, and characteristics of Ego States
The SARI model as a 4-stage treatment of EST
Dissociation and the dissociative spectrum
Neurobiology of trauma and resilience
Polyvagal theory and neuroception
Stabilization with SEST
Working with containment and touch
The program uses hypnotic and non-hypnotic methods to connect with adaptive, introjected, and trauma-related states while building safety, stabilization, and balance of the nervous system.

Australian Resource Therapy Institute
The Australian Resource Therapy Institute offers a Clinical Resource Therapy Certification Program (10 days), which provides intensive, experiential training toward becoming a Certified Clinical Resource Therapist.
EST Training vs. IFS: Understanding the Distinction
Internal Family Systems (IFS) and Ego State Therapy are both powerful parts-oriented therapies, but they come from different traditions, use different language, and follow different mechanisms of change.
Similarities
Both approaches:
View the personality as composed of distinct parts or states
Help clients process trauma and form a coherent, mentally healthy Self
Recognize a conflict-free core
Are used to treat trauma, PTSD, and mental health conditions
Differences
Aspect | Ego State Therapy | Internal Family Systems |
|---|---|---|
Origins | Psychodynamic/hypnotic tradition | Family systems theory |
Mechanism | Uses hypnosis to activate implicit ego states | Uses direct access and unburdening |
Emphasis | Functional states and resourceful ego states | Self-leadership and the "Self" |
Structure | Can vary significantly among practitioners | More structured and standardized |
As one comparison notes, "EST places greater emphasis on functional" aspects. While both approaches are valuable, understanding the distinction helps clinicians choose the training that aligns with their clinical orientation.
Training Formats and Modalities
Online Training
Many EST training programs are now available online. The Woltemade Hartman Institute offers an online English Ego State Therapy training, making this specialized training accessible to a global audience. Online courses often combine live webinars, demonstrations, and supervised practice.
EMDR Integration
Several training programs focus on integrating Ego State Therapy with EMDR, particularly for complex trauma and dissociation. These programs teach clinicians to:
Assess dissociative symptoms
Use the Dissociative Table Technique to identify parts of self
Integrate ego states into the eight phases of EMDR
Work with C-PTSD and dissociative disorders
Hypnosis Integration
Given the Watkins' background in hypnosis, many EST training programs include hypnotic techniques. EST is considered "very suitable intervention strategy for posttraumatic stress reactions, dissociation as a result of trauma, as well as for a variety of psychosomatic diseases".
FAQ
Who is eligible for Ego State Therapy training?
Most programs require participants to be licensed mental health professionals. The Woltemade Hartman Institute specifies eligibility for "Licensed Psychologists, Medical Doctors and Individuals working in health-related fields". Some programs may accept other health professionals, but admission is subject to the approval of the training director.
How long does Ego State Therapy certification take?
Certification typically requires completing a series of consecutive workshops or seminars. For example, the Woltemade Hartman Institute program consists of four 3-day seminars held over several months. The AICHP offers a 70-hour training program. The SEST training is 12 days delivered in four 3-day modules.
Can I take EST training online?
Yes. Several programs offer online training options. The Woltemade Hartman Institute offers an online English EST training, and there are various online courses available through EMDRIA and other platforms.
How is Ego State Therapy different from Internal Family Systems (IFS)?
Both are parts-oriented approaches, but EST comes from a psychodynamic/hypnotic tradition and uses hypnosis to access implicit ego states, while IFS comes from family systems theory. EST places greater emphasis on functional states and can vary more among practitioners.
Is Ego State Therapy evidence-based?
Ego State Therapy has a solid theoretical foundation and is recognized by professional organizations such as the International Society for the Study of Trauma and Dissociation (ISSTD). Research on EST outcomes is growing, particularly in the context of trauma and dissociation.
What are the prerequisites for EST training?
Prerequisites vary by program. Some programs require prior training in hypnosis or EMDR, while others are designed for beginners. The Woltemade Hartman Institute describes Seminar 1 as "designed for both beginners and the more experienced practitioner". Programs with EMDR integration typically require prior EMDR training.
