This report presents Texas Assessment of Academic Skills (TAAS) performance results and results on the Texas Educational Assessment of Minimum Skills (TEAMS) in October 1990. This volume is comprised of the following sections: (1) Section I, an executive summary of TAAS performance for each grade level; (2) Section II, an overview of the program and detailed information needed to understand these results; and (3) Sections III through VIII, which present summaries of the October 1990 assessment for grades 3, 5, 7, 9, and 11 and the TEAMS results for grades 11 and 12. Chapter IX presents results for the grade 3 Spanish version of TAAS. Students across the grades did well on the written composition, but performance was markedly poorer with regard to spelling, capitalization, and punctuation. At each grade level, more students achieved the academic recognition level in reading than in any other subject area. In mathematics, performance was better on objectives in the concepts domain than in the operations domain. At grade 11, 35% of the students had not mastered one or more sections of the exit level (TEAMS) test. Thirty-six figures summarize student performance. Seven appendices provide greater detail about the testing process. (SLD)
