The institutions will sign a memorandum of understanding today that will result in graduating students receiving dual-badged testamurs from next year.

The degrees will be recognised as if they were Charles Sturt degrees.

Students may also enrol in any units of study with Charles Sturt University if the courses are not offered by Avondale.

Today's signing will also formalise Charles Sturt University's role as a mentor and adviser to Avondale College, which has been working towards university accreditation for almost 20 years.

The role will primarily include assessing and benchmarking Avondale's governance, learning, teaching and research quality standards and sharing resources on a cost-for-service basis.

Established by the Seventh-day Adventist Church in 1897, Avondale College offers undergraduate, post-graduate and vocational courses that "seek to develop the whole person".

Charles Sturt University vice-chancellor Andrew Vann said many of the college's programs, particularly in theology, were similar to those offered at the university.

"Its mission and activities resonate with our values and priorities," Professor Vann said.

Avondale College president Ray Roennfeldt said staff from both institutions would benefit from increased collaboration in teaching and research.

"Avondale will always offer a defined number of courses, but the course and unit options for our students may increase through online study at Charles Sturt," Professor Roennfeldt said.

The collaboration will build relationships between Charles Sturt and other Adventist Church entities, such as Sydney Adventist Hospital, where Avondale will negotiate clinical places for Charles Sturt allied health students.

The memorandum of understanding is not legally binding but is valid for five years and can be extended or suspended by mutual agreement.
