Getting a full-time job proved more difficult for graduates of Curtin and Edith Cowan universities, according to the Good Universities Guide 2014.
The annual guide rates institutions on their graduate outcomes and educational experience based on student surveys.
The latest edition shows the University of WA, Murdoch and Notre Dame universities received four and five star ratings for getting a job, compared with one star each for Curtin and Edith Cowan.
But UWA did not fare as well as either of those for teaching quality, scoring just one star in that category.
A spokesman for UWA said that because its students were high achievers, they had equally high expectations.
He said UWA rated well on graduate outcomes because its faculties had developed close connections with employers.
"Many of our students participate in internships, practicums, clinical experiences and other work placements that contribute to them being work-ready," the spokesman said.
Asked why Curtin students rated it so poorly on getting a job, deputy vice-chancellor for education Jill Downie said last year's graduation satisfaction survey showed 94 per cent of domestic graduates secured a job four months after finishing their course.
Murdoch deputy vice-chancellor for professional services Jon Baldwin said it was pleasing that ratings had improved in six categories, particularly getting a job.
Kerry Cox, vice-chancellor of Edith Cowan University which scored five stars for teaching quality for the fifth year in a row, said it focused on providing students with high-quality learning experiences.
Notre Dame was rated WA's best all-round university, excelling in student experience and graduate outcomes, even though it received only one star for staff qualifications.
This year was the first time ratings were included for student retention, based on the percentage who continued on to a second year of study.Murdoch and ECU rated two stars for retention, while Curtin and UWA scored three. Notre Dame was not rated on that measure.
