GMU Center for Psychological Services



The George Mason University Center for Psychological Services (GMU CPS) is a community-located and community-serving psychological services office that serves as the primary training clinic for the graduate students in Clinical and School Psychology at GMU, a field placement for graduate students in social work, and an externship training site for doctoral-level clinical psychology graduate students from other local universities.

GMU CPS offers a range of evidence-based treatment services and has a sliding scale fee so that all people have the opportunity for assessment and treatment regardless of their income.

We offer a variety of assessment options, primarily psychoeducational testing and mental health evaluations (many of which are court-ordered) as well as therapy for children, adolescents, and adults. We do individual therapy, family therapy, couples counseling, and groups.

All trainees are very closely supervised by licensed psychologists who are faculty and adjuncts within the Psychology Department at George Mason University. The GMU CPS adheres to a clinical science model of training and, therefore, all trainees receive training in, and are expected to practice utilizing evidence-based assessment and psychotherapy techniques. While faculty supervisors at GMU CPS maintain a primarily Cognitive-Behavioral orientation, other evidenced-based orientations (e.g., DBT, Family Systems) are presented and trainees are provided opportunities for integrating various evidence-based techniques as appropriate in understanding and addressing a client’s needs.

Training Clinic Model

Services at the GMU Center for Psychological Services are primarily provided by graduate student clinicians training to become clinical and school psychologists. Our trainees are not yet licensed, but all of the services they provide are supervised closely by GMU-affiliated faculty who are licensed to practice. You will be provided with this supervisor’s name at the start of your therapy or assessment.

As trainees are being supervised, sessions are observed, usually via audio or video recording, and the supervisor reviews the recordings to ensure the provision of the best care possible. The recordings are confidential, deleted at the end of treatment/assessment, and are used only to provide feedback to the trainees. This approach is widely used in the training of clinical and school psychologists and other mental healthcare providers.

If you are not comfortable with this arrangement, we occasionally have licensed providers and affiliated faculty with openings for assessment and therapy services. We can also provide you with referrals to licensed professionals in the community.

Being a training clinic also affects fees and billing. As a training clinic, our fees are lower than what psychologists in the community typically charge.
