The procedures and results of a pilot program in a statewide assessment of learning in Colorado are presented. Findings and conclusions of the project in which the Common Status Measures of the U.S. Office of Education were administered to 12,000 pupils in 31 school districts concurrently with objectives-referenced items developed by the Colorado Department of Education are reported. Educational needs were concluded to exist in Colorado on the basis of assessment results. Objectives related to general goals, developing test items, sampling items and students by multi-matrix techniques, and analysis of resultant data are fully described. Substantive findings indicate the degree to which certain curricular objectives are being achieved in Colorado schools. Appendices present the rationale and procedures of assessment along with some 300 objectives stated in six common curricular areas: health, language, arts, mathematics, music, physical education, and science. More extensive reports of the results may be found in a set of "Working Papers" developed at each grade level in the various curricular areas. (Author/PR)
