Data are presented in support of the validation of the competency-based basic skills curriculum which was implemented in the District of Columbia Public Schools in 1978-79. Strategies for conducting the validation are outlined in detail, including review of tests used, orientation of participants, integration of curricular hierarchies, and development of teaching methods. A description of overall data processing activity is included, as well as codes for each objective in the instructional sequence: language arts--prekindergarten-grade 9; and science--grades 1-9. Tables describing the number of students attempting and mastering each objective are included, as are charts illustrating the hierarchical relationships between objectives, and questionnaires used for data collection. The summary chapter indicates that the language arts/English and science curricula are sound, useful, and appealing; and that the validation model is effective, applicable, and worthy of being replicated.
