How to Become a Child Therapist in California
There is no California license called child therapist. A child therapist is a licensed mental health professional who focuses on children, adolescents and their families, and the license whose training is built most directly around that work is the licensed marriage and family therapist (LMFT). The path has three parts: a qualifying master's degree, the supervised experience and exams that lead to a license, and optional training in child-focused methods such as play therapy, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) or Parent-Child Interaction Therapy (PCIT).
Private credentials in those methods sit on top of the license rather than replacing it. The Registered Play Therapist credential and TF-CBT certification both require a license before they can be held, so most of the work of becoming a child therapist happens on the way to licensure.
What Does a Child Therapist Do?
A child therapist assesses and treats emotional, behavioral and relational problems in children and adolescents. California's definition of marriage and family therapy describes this work closely: it applies psychotherapeutic and family systems methods to assess, evaluate and treat relational issues, emotional disorders, behavioral problems and mental illness, through individual, relationship, family or group interventions.
Many child-focused treatments bring parents or caregivers into the room. TF-CBT certification requires cases in which a caregiver takes an active part, and PCIT is built around a parent and child working together through two phases, Child-Directed Interaction and Parent-Directed Interaction.
Sessions with children also call for skills that adult therapy training does not fully cover. A child therapist has to build a vocabulary for feelings a child may not have words for yet, explore questions about identity without leading the answer, and hold limits firmly enough to keep the work safe without damaging the relationship.
Is "Child Therapist" a Separate License in California?
No. California has no separate child therapist license. The Board of Behavioral Sciences licenses four professions, marriage and family therapy, professional clinical counseling, clinical social work and educational psychology, and the Board of Psychology licenses psychologists. Child therapy is an area of focus practiced under one of these licenses, in the same way that couples therapy and trauma therapy are.
The LMFT is the license most closely tied to children and families. One of the degree titles that qualifies for it is marriage, family, and child counseling, and its supervised experience requirement includes at least 500 hours diagnosing and treating couples, families and children. Other licenses can also lead to work with children, and the guide to choosing a therapy credential in California compares them. Play therapy and the other child-focused credentials are certifications, which the guide to licenses, certifications and registrations explains.
What Underlying License Do You Need?
To practice independently as a child therapist, you need a California license. For a master's-level clinician who wants to focus on children and families, the license built around that work is the LMFT, described in full in the guide to what an LMFT is.
The LMFT path starts with a qualifying master's degree of at least 60 semester units that includes a supervised practicum. The license requires 3,000 hours of supervised experience over at least 104 weeks. Up to 1,300 of those hours can be earned as a trainee before the degree is awarded, and the rest come after graduating, once you register with the Board of Behavioral Sciences as an Associate Marriage and Family Therapist (AMFT). At least 1,750 of the hours must be direct counseling, and at least 500 must involve diagnosing and treating couples, families and children. Associates must take the California Law and Ethics Exam in each registration renewal cycle until they pass it, and the LMFT Clinical Exam comes after the hours are complete and the Board approves the licensure application. The guide to how long it takes to become an LMFT lays out the timeline.
Supervised work with children during practicum and the associate years does double duty. It counts toward the 500 hours the license requires, and for anyone planning to pursue the Registered Play Therapist credential, supervised play therapy during graduate practicum and the associate years can count toward the credential's experience requirement as well.
What Is the Registered Play Therapist Credential and How Do You Earn It?
The Registered Play Therapist (RPT) credential is issued by the Association for Play Therapy (APT). It requires a clinical license, specific graduate coursework, play therapy instruction and supervised play therapy experience, and the play therapy instruction, experience and supervision must be completed over a period of two to ten years.
| Requirement | RPT standard (application effective April 1, 2025) |
|---|---|
| Degree | Master's or higher clinical mental health degree in counseling, marriage and family therapy, psychiatry, psychology or social work, with coursework in child development, theories of personality, principles of psychotherapy, child and adolescent psychopathology, cultural and social diversity, and ethics |
| License | A current, active and unconditional state license that permits independent clinical practice |
| Play therapy instruction | At least 150 hours from accredited universities or APT Approved Providers, at least 75 of them in person |
| Supervised experience | At least 350 direct client contact hours of play therapy, supervised by a Registered Play Therapist-Supervisor (RPT-S) |
| Supervision | At least 35 hours of play therapy supervision, no more than 15 of them in a group, plus five observed sessions |
| Time frame | No less than two and no more than ten years from the start of accrual |
| Application fee | $210 for APT members and $340 for non-members (2025 application) |
The license requirement shapes the order of steps in California. APT requires a license that permits independent practice, and the associate registration is a supervised status, so a California MFT applies for the RPT after becoming an LMFT. The instruction and experience can be built earlier: APT accepts play therapy hours from graduate practicums and internships if they follow its phase approach, and hours earned since January 1, 2020 must be supervised by an RPT-S. A therapist who has held the RPT for three consecutive years and has three years and 3,000 direct client contact hours of experience after licensure, among other requirements, can apply to become an RPT-S and supervise others.
What Are TF-CBT and PCIT Certification?
TF-CBT and PCIT certifications cover two specific child treatments, each with its own training and case requirements.
The TF-CBT National Therapist Certification Program certifies therapists in Trauma-Focused Cognitive Behavioral Therapy. It requires a master's degree in a mental health discipline and a professional license that includes a passed licensing exam, which in California means certification normally follows LMFT licensure. Candidates complete the online TF-CBTWeb course and a live training of two or more days led by a treatment developer or approved national trainer, then join consultation calls twice a month for six months or monthly for twelve months while carrying a child and adolescent trauma caseload. They must complete three TF-CBT cases, at least two with active caregiver participation, measure trauma symptoms with a standardized instrument before and after treatment, and pass a knowledge test with a score of 80% or higher. The total certification fee is $250. The guide to becoming a trauma therapist covers trauma credentials more broadly.
PCIT International certifies therapists in Parent-Child Interaction Therapy. It requires a master's degree in a mental health field and independent licensure or license eligibility, a term the organization does not define. Candidates complete an approved basic training of about 40 hours, then 12 to 18 months of consultation with a certified PCIT trainer, during which they take at least two PCIT cases from start to graduation with fidelity in both phases. Certification is valid for two years and requires ongoing continuing education to maintain.
Is a Child Therapy Credential Required to Practice in California?
No California law requires a play therapy, TF-CBT or PCIT credential to treat children. These credentials come from private professional organizations, and the legal requirement is the license itself, or registration and supervision while you earn it. Employers and funded programs can set their own training expectations, so a position built around a specific treatment may ask for training in that model.
Two legal topics come up early in work with children: when a minor can consent to therapy without a parent, and a therapist's duty to report suspected child abuse. The guides to minor consent and parent access to records and mandated reporting deadlines cover both.
Can a Child Therapist Work in a California School?
Yes, though school counseling positions require a separate credential. When a position's duties substantially align with those of a Pupil Personnel Services (PPS) credential, the credential is required, judged by the duties rather than the job title. The school counseling specialization requires at least 48 semester units in a Commission-approved school counseling program, including a practicum with school-aged children, and an LMFT license does not authorize it.
School districts also employ marriage and family therapists for mental health services that credentials do not cover, and that work must be supervised by a PPS credential holder. The guide to school-based MFT careers covers this setting in more depth.
Why Clinical Skill Rehearsal Matters for This Work
Child therapy depends on skills that are hard to learn from reading alone. Naming a feeling for a child who does not have the word yet, following a question about identity without steering it, and holding a limit while keeping the relationship intact all happen in tone, pacing and improvisation, with a young client who may be crying, silent or testing the rules.
Knowing about therapy is not the same as being able to do therapy with a real client (Rousmaniere and Vaz, 2025). Deliberate practice targets that gap by having therapists rehearse specific skills with feedback from a supervisor or peer. Sentio's free child therapy skills videos demonstrate three of these skills, naming feelings, exploring identity and setting limits, for trainees and therapists to rehearse in peer practice or supervision.
A Closer Look at One Program: The Sentio MFT Program
Programs differ in how much skill rehearsal and supervised client work they build into training. The Sentio MFT program is a 20-month, 60-credit Master of Arts in Marriage and Family Therapy, taught online in weekly live classes with an in-person residency in Los Angeles at the start of each semester. Students train in deliberate practice every week, and the curriculum includes coursework on therapy with children and adolescents.
Every student has a guaranteed practicum at the Sentio Counseling Center, an online counseling center that serves diverse, low-income clients and specializes in serving clients with trauma. Students begin seeing clients in their second semester, complete more than 400 supervised clinical hours before graduating, and have supervisors who review video of their sessions. In the Class of 2026, the program's first graduating class, every graduate was registered as an AMFT within six weeks of graduation and working in the field within three months.
Making Your Decision
The license is the decision that matters most, because every child-focused credential is built on it. If you want a license centered on children and families, the LMFT is the most direct route, and its required hours with couples, families and children give you child and family experience before you are licensed.
The credential choice can wait, but the planning should not. If play therapy is your goal, look for practicum and associate placements where an RPT-S can supervise play therapy hours, since play therapy hours earned since 2020 without one do not count toward the RPT. If trauma work with children draws you, TF-CBT certification follows licensure, and a placement with a child trauma caseload prepares you for it.
Frequently Asked Questions
Is "child therapist" a licensed profession in California?
No. California has no separate child therapist license. Child therapy is an area of focus practiced under a state license, most directly the licensed marriage and family therapist (LMFT), whose supervised experience requirement includes at least 500 hours diagnosing and treating couples, families and children. Play therapy, TF-CBT and PCIT credentials are private certifications that sit on top of a license.
What license do I need to become a child therapist in California?
You need a California mental health license to practice independently. For a master's-level clinician focused on children and families, the license built around that work is the LMFT, which requires a qualifying master's degree, registration as an Associate Marriage and Family Therapist, 3,000 hours of supervised experience over at least 104 weeks, and passing the California Law and Ethics Exam and the LMFT Clinical Exam.
How do you become a Registered Play Therapist?
The Association for Play Therapy requires a master's or higher clinical mental health degree with specific coursework, a state license that permits independent practice, at least 150 hours of play therapy instruction (75 of them in person), at least 350 direct client contact hours of play therapy supervised by a Registered Play Therapist-Supervisor, and at least 35 hours of play therapy supervision with five observed sessions, with the play therapy instruction, experience and supervision completed over two to ten years.
Can an AMFT become a Registered Play Therapist?
Not while registered as an associate. The Association for Play Therapy requires a license that permits independent practice, and the California associate registration is a supervised status, so the credential follows LMFT licensure. Associates and graduate students can still build the instruction and supervised play therapy experience in advance, as long as the experience follows APT's phase approach and is supervised by a Registered Play Therapist-Supervisor.
Do you need a certification to do play therapy in California?
No California law requires a play therapy certification. The legal requirement for treating children is a license, or an associate registration with supervision. The Registered Play Therapist credential from the Association for Play Therapy is voluntary, though it documents specialized training, and employers or funded programs can set their own expectations for positions built around a specific treatment.
Can an LMFT work as a school counselor in California?
A school counseling position whose duties align with the Pupil Personnel Services credential requires that credential, and an LMFT license does not provide it. The school counseling specialization requires at least 48 semester units in a Commission-approved program. School districts do employ marriage and family therapists for mental health services that credentials do not cover, under the supervision of a PPS credential holder.
