Developed for the Basic Skills Testing Program (BSTP) in New South Wales, Australia, this teacher's manual describes the Green Series 3 of the ACER (Australian Council for Educational Research) Tests of Basic Skills. The two tests in this series, Aspects of Literacy and Aspects of Numeracy, were administered statewide by government school classroom teachers in August, 1990 to a population of approximately 57,000 Year 3 students. In this manual, a discussion of the rationale behind the tests and an overview of the tests is followed by a description of procedures for administering the tests and a detailed explanation of the method for analyzing the results. Appendixes include descriptions of students who fall in particular score ranges and bands of skills, diagnostic map charts, group analysis charts, and answers for the tests. Sample copies of the Aspects of Literacy and Aspects of Numeracy test books and the "Young Aussie" (Green Series) magazine are included. (MM)
