1. From documentation found on the UNI websites on academic probation and scholarships, the course catalog, and the student/advisor view on myUniverse, UNI uses the cumulative GPA which includes grades transferred in from other institutions in determining whether students maintain scholarships, are placed on academic probation, and achieve the necessary GPA for graduating from the university for given majors

[note there is conflicting information at different places regarding UNI cumulative GPA and cumulative GPA, it may be the intent is to use the UNI GPA, but this is not always stated an could be confusing for advisors, students, etc...]
2. The curriculum is in principle controlled by UNI faculty, however the faculty have no control over the grades assigned by other institutions.
3. It is Regents and state policy that courses regulated by articulation agreements should be counted for credit, there is leeway towards whether a particular class may count towards a given major, whether a student may need to be required to pass a competency exam to take a course which uses the transfer class as a pre-requisite, and to the best of my knowledge there is no mandate to use the grades from any other institution in calculating cumulative GPA.

3. The present calculation of UNI cumulative GPA and cumulative GPA is referred to inconsistently and can create confusion for students, faculty, and advisors.

Therefore, be it resolved that the University Faculty Senate requests that grades from transfer credit no longer be used to calculate a cumulative GPA and instead that cumulative GPA be reserved only for courses taken at UNI. Also that grades for transfer credit not be used except for fulfilling entrance requirements. In cases in which articulation agreements exist, minimum grade requirements for university credit should be followed as according to these agreements. Otherwise, university should continue to make a case by case (or establish appropriate guidelines for) determination of whether credit should be achieved in consultation with the pertinent department. Regardless of articulation agreements, the faculty within a given department are free to set guidelines regarding whether a specific course (including the grade achieved in that course) should be used to fulfill the requirements for a specific course listed within a major, minor, or certificate and further that faculty within a department are free to create or use a standardized examination to determine if a student has proficient knowledge to enroll in any class that utilizes a transferred class as a pre-requisite.
