Evaluating the Validity of Texas 2 STEPS

The Texas 2 STEPS Evaluation Tool was assessed for face validity. Thirty Certified Orientation and Mobility Specialists (COMS) piloted the tool while evaluating children under the age of five years. Each participant was asked to evaluate their comfort level working with this population and report the number of years’ experience they have working as a COMS. The majority of participants found the tool useful for assessing orientation and mobility (O&M) skills in children. The Texas 2 STEPS was also found to be user friendly regardless of the COMS years of experience. Together these findings indicate that the Texas 2 STEPS has the potential to be a valid and reliable tool for assessing O&M skills in children with vision impairment.
