This bulletin discusses the mathematics and science course enrollment trends of secondary students in Australia, which are of national concern because of the low participation rates overall and because of the gender imbalance in enrollment numbers. Statistics are reported for 12th-grade mathematics and science course enrollment, and expectations and solutions are discussed. Among the recommendations are for teachers and educators to faciitate and help devise strategies that will increase participation in science and mathematics and to increase the mathematical ability of Australia's secondary school students.
