The Mathematics Achievement Test Project (MATP) was set up by the Learning Assessment Branch of the Ministry of Education of British Columbia to develop testing materials to assist teachers throughout the province in the task of evaluating students' performance in mathematics. The two major objectives of the project were to construct "banks" of test items referenced to the curriculum guide for mathematics (1978 edition) in grades 3, 7, and 10 and use these items to construct tests which could be used either as achievement measures or diagnostic tests. Chapter 1 of this document discusses the strand test concept and the administration and scoring of the strand tests. Chapter 2 describes the development of the items. Chapter 3 describes statistical procedures. The appendices include lists of the MAPT strands and the item writers. (Author/MK)
