Abstract

The Model A and Model C Title I evaluation options were compared by using both options to measure the effectiveness of handicap intervention in a Head Start program. Two hundred three children in Jackson County (Oregon) were pretested with the Developmental Indicators of Learning Test (DIAL), the Peabody Picture Vocabulary Test (PPVT), the Visual-Motor Integration Scale (VMI), and the Carrow Elicited Language Inventory (CELI). The 43 children who scored below the predetermined cut-off level were placed in a six-month intervention program. One hundred forty-nine children remaining in the Head Start program in May were posttested with the same tests. Model A analysis of mean scores of the intervention group indicated significant score change on all three testing instruments. Model C analysis indicated no positive score change. It was posited that the Model A effect in this project was large because it combined a positive intervention effect with a positive general program effect. The Model C option showed no effect because the estimated nonintervention scores were very large due to the large positive score change in the nonintervention group.
