Significant Drop in Advanced Mathematics and STEM Enrolments for HSC Year 12

Recent data from the NSW Education Standards Authority reveals a substantial decline in student enrolments for advanced mathematics and key STEM subjects between Year 11 and Year 12.

Enrolment figures show more than 8,000 students abandoned the advanced mathematics course between Year 11 and Year 12, representing approximately one-third of students across the state who were enrolled in the subject.

The trend extends beyond mathematics. More than a quarter of Year 11 students enrolled in physics, chemistry, and engineering also dropped each of those subjects before starting Year 12.

This decline occurs amid broader national efforts to increase graduate numbers in science, technology, engineering, and mathematics (STEM) fields. Students are required to complete 10 units of study in their final HSC year, compared to 12 units in Year 11, which often leads to subject refinement.

Expert Perspectives on the Decline

Education professionals have offered several insights into the reasons behind this subject drop-off.

Miriam Lees, Mathematics Association of NSW Education Consultant, emphasized the importance of the advanced course for future study. She stated that calculus skills from advanced mathematics equip students with critical thinking skills for university.

"If your undergraduate degree requires mathematics, advanced is the minimum you need to ensure you can meet those requirements," Lees said.

Kate Geraghty suggested the initial enrolment could be linked to parental pressure, with students taking courses for which they were not well-suited, and that teacher advice may not always be followed.

Professor Eddie Woo from the University of Sydney described the decline as "a feature, not a bug" of the HSC system. He noted that few students have a clear post-school plan in Year 10 and often refine their subject choices later as their interests and goals become clearer.

A NSW Education Standards Authority spokeswoman said student subject adjustments are common and occur for various reasons, including changes in post-school plans, passion for a course, engagement with content, or ability.

Student Experiences

For many students, the decision to drop down is a practical one based on workload and future aspirations.

Year 12 student Jasmine Edwards dropped from advanced to standard mathematics, stating the work required for the harder course was not worth the reward for her future plans.

Another student, Stevie Crosby, found the Year 12 advanced mathematics content significantly more difficult and felt discouraged by the jump in complexity.

Broader Educational Context

The discussion around declining STEM enrolments is not new. Former NSW Department of Education head Mark Scott has previously linked declines in higher-level maths enrolments to the potential influence of primary school teachers' attitudes on students' long-term perceptions of the subject.
