The Iowa Department of Education collects information on joint enrollment from Iowa's 15 community colleges. Jointly-enrolled students are high school students enrolled in community college credit coursework. Most jointly-enrolled students enroll through Senior Year Plus programs, such as concurrent enrollment. Other students enroll independently as tuition-paying students, or enroll in courses delivered through contractual agreements that do not meet the definition of "concurrent enrollment." This report consists of academic year (AY) and trend data on joint enrollment, including headcount enrollment, credit hours taken, student demographics and enrollment by program type and offering arrangement. All data included in this report is taken from the Community College Management Information System (MIS), and confirmed by each college, unless noted otherwise.
