Although the IAI is expected to facilitate student transfer statewide, there continue to be valid reasons for inter-institutional articulation tools such as 2+2, course articulations, and transfer guides:
First, the IAI will not articulate every possible baccalaureate major, but only those that are most commonly chosen by students and those that are offered by a sizable number of institutions.
Further, 2+2 agreements are especially useful in those technical and professional fields in which education level parallels career advancement-Generally, fields in which students gain technical skill competence first and then the broadening perspectives gained from general education.
Also, 2+2 agreements and transfer guides can facilitate transfer between different but complementary programs, such as health care provider and management.
Also, course by course articulations can be helpful to reverse transfers.
Finally, because these agreements are between just two institutions, it can be much more detailed than the more general IAI statewide agreements.
