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 Postsecondary Enrollment Options (PSEO) and 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. For more information about Senior Year Plus programs, please refer to the department's website. This report consists of fiscal year (FY) 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 otherwise noted. The following 15 community college profiles are included: (1) Northeast Iowa Community College; (2) North Iowa Area Community College; (3) Iowa Lakes Community College; (4) Northwest Iowa Community College; (5) Iowa Central Community College; (6) Iowa Valley Community College District; (7) Hawkeye Community College; (8) Eastern Iowa Community Colleges; (9) Kirkwood Community College; (10) Des Moines Area Community College; (11) Western Iowa Tech Community College; (12) Iowa Western Community College; (13) Southwestern Iowa Community College; (14) Indian Hills Community College; and (15) Southeastern Community College.
