The Critical Race Theory Measurement (CRTM) was developed to evaluate the understanding of the six major principles of CRT and the significance of race relating to the preparation of practitioners providing services to people of color. The objective of this study was to evaluate the scale's psychometric properties. The CRTM self-assessment instrument measures the six Critical Race Theory principles. It consists of 19 items assessing endemic racism, the social construction of race, differential racialization, convergence/determinism, racial narratives, and intersectionality. The validation of the CRTM was based on its administration to 175 social work and counseling practitioners. This paper discusses the importance and needs to develop tools like the CRTM scale that can be utilized in practice to assess practitioners' knowledge and understanding of CRT. The overall findings confirmed the CRTM items and the data was suited for parametric statistical analyses.
