The purpose of this study was to provide initial validation of a scale intended for use by orientation and mobility (O&M) specialists to determine recommended type and amount of O&M services for students on their caseloads based on each student’s identified needs. The validity and reliability of the Orientation & Mobility Visual Impairment Scale of Service Intensity of Texas (O&M VISSIT) were calculated using mixed-methods survey research design, with purposive expert sampling. The O&M VISSIT was found to be significantly valid in social and content validity and moderately valid in consequential validity, and is a moderately reliable tool to help determine the appropriate type and amount of O&M services for all students on the O&M specialist’s caseload.
