The admission of students with ATARs in the low 50s into some NSW teaching degrees has prompted calls for a minimum entry requirement to be introduced across the state's universities.

Data from the Universities Admissions Centre released on Monday shows ATARs in the low 60s were the standard for entry into teaching courses at the Australian Catholic University, University of Newcastle and the University of Canberra, while some students with marks below that were eligible after adjustment factors were considered.

A student with a raw ATAR of 49.65 was offered a place in the ACU's secondary teaching degree in the humanities, and a raw rank of 48.30 was accepted for the University of Canberra's primary education degree.

While the median ATAR of students accepted in those courses was in the 60s or 70s, Teachers Federation president Maurie Mulheron said the standard should be higher. Almost half of NSW HSC students achieved an ATAR above 70, which was this year introduced as the mandatory standard for entry to teaching courses in Victoria.
