The CLVT uses functional vision evaluation instruments to assess visual acuity, visual fields, contrast sensitivity function, color vision, stereopsis, visual perceptual and visual motor functioning, literacy skills in reading and writing, etc. as they relate to vision impairment and disability. The CLVT also evaluates work history, educational performance, ADL and IADL performance, use of technology, quality of life and aspects of psychosocial and cognitive function.
The O&M test is designed to assess entry-level O&M knowledge of prospective O&M specialists. The 140 multiple-choice / multiple-select items focus on knowledge of basic principles of the discipline of O&M and on the application of that knowledge in working with individuals who are blind and visually impaired. The questions relate to preschool, school-aged, and adult individuals who are blind and visually impaired.
