Schools, universities and the ATAR system are driving students away from vital science, maths and technology subjects, according to chief scientist Alan Finkel, who has strongly defended the importance of STEM in a report to the country's education ministers.

Dr Finkel has urged a review of the university entrance system, the reintroduction of maths as a prerequisite for relevant university courses and the tracking of students' performance from cradle to grave using a controversial ID system.

The report, currently being considered by the Education Council but obtained by Fairfax Media, takes particular aim at the Australian Tertiary Admission Rank, used by 73 per cent of school leavers to gain entry to university.

The report found high school students are choosing easier subjects in which they can get a higher score to maximise their ATAR rank, citing NSW research and testimony from educators.
