| Summary: | The project was designed to develop an alternate testing method for the visual acuity assessment of preschool children with handicaps. Additional project objectives included evaluation and modification of existing experimental procedures for discrimination training and visual acuity testing of preschool handicapped children; establishment of a criterion for referral for vision screening of 18-to 48-month old children; dissemination of subjective visual acuity procedures to field test sites; and identification of marketing sources to make the materials commercially available. Data on a battery of visual acuity tests administered to preschoolers are presented, indicating that the PVAT (Parsons Visual Acuity Test) had sufficient reliability and validity to serve as a visual acuity screening instruments for preschoolers. Following field test reports and descriptions of dissemination activities, the PVAT manual is presented. (Author/CL) |
