The CTVF was designed to be a brief and meaningful assessment device to accurately detect and discriminate visual processing problems. The CTVF can be used by multiple professionals: learning disability teachers, reading specialists, etc., and no specific training is required. The CTVF is appropriate with populations manifesting visual-perceptual problems secondary to acute or chronic disorder processes. The CTVF was developed on 1,200 individuals. Excellent reliability and validity statistics are included in the manual.
