The purposes of this study were (1) to ascertain the total absolute change scores between student basic interest scale scores on the Strong-Campbell Interest Inventory (SCII) and like scores on the audio interest inventory (All), and the audio-visual interest inventory (AVII), which are based on the SCII; and (2) to ascertain if a statistically significant relationship exists between students with high reading ability and students with low reading ability, when different test-retest inventory administration methods are used.

The problem with which this investigation is concerned is that of determining perceived attitudes of self-concept of educationally disadvantaged students in special vocational environments, other vocational students, and academic students as measured by the Piers-Harris Children's Self-Concept Scale. The hypotheses formulated to carry out this study included: 1. There is no significant difference in the mean attitude self-concept score of vocational education students, academic students, and educationally disadvantaged students (CVAE) as measured by the Piers-Harris ChildrenIs SelfConcept Scale. 2. There is no significant difference in the mean attitude self-concept scores as measured by the Piers-Harris Children's Self-Concept Scale between vocational education students, academic students, and CVAE students and number of years of placement in a vocational program, academic program and CVAE program. The Piers-Harris Children1s Self-Concept Scale was administered to 311 students from the CVAE, vocational, and academic programs in the Birdville Independent School District, Fort Worth, Texas and Denton Independent School District, Denton, Texas.
