This item bank was compiled by the Australian Council for Educational Research (ACER) to help teachers at the secondary school level construct objective tests in mathematics. The multiple-choice items were written by teachers who attended ACER writing workshops. The questions are classified according to their subject content and the cognitive skills required to answer them; the correct response is also indicated. These classifications are provided through five-digit content axis numbers. Classifications in the content axis include abstract algebra; relations and functions; analysis; geometry; trigonometry; applied mathematics; and statistics and probability. The item complexity is indicated on a five-point scale, based upon the number of students in a test group who gave correct responses. Instructions for reproducing the tests and answer sheets are also included. (Author/JAC)
