The Student Data Report for 2005-06 is the 24th annual comprehensive publication of student data derived from the Oklahoma State Regents Unitized Data System (UDS), which has been in place since 1977. Each semester, approximately 75 data elements are gathered for each student (a person who enrolled, had a class/grade action, and paid fees) in Oklahoma higher education.

In 2005-06, there were 30 data reporting entitites, institutions, and branch campuses in The Oklahoma State System for Higher Education. Some of the private institutions did not participate in the UDS, thus grand totals including private institutions are not complete. There are 25 public higher education institutions, 20 branch campuses, and 5 learning centers in Oklahoma. Oklahoma has 12 private higher education instituions that are regionally accredited.
