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.
