In response to increasing assessment and accountability requirements, Mt. Hood Community College, in Oregon, developed an assessment matrix specifying major accountability requirements and established a calendar to help departments understand the necessary sequences for fulfilling these requirements. The matrix lists the various measures or indicators of effectiveness grouped among headings for student retention, outcomes, and success; special populations and disadvantaged; and other program and institutional indicators. For each indicator, the matrix also describes the purpose of assessment in terms of the following internal or external accountability sources: (1) accreditation; (2) internal program review; (3) the state quality assurance plan for all professional technical state approved programs; (4) state key effectiveness indicators; (5) the Community College Roundtable core indicators; and (6) the Joint Commission on Accountability Reporting. The calendar lists the major assessment pieces that need to be completed over a 2-year period. The integrated assessment approach has yielded positive results and improved communication among institutional researchers, administrators, and faculty at the college. Since the various accountability requirements contain inconsistencies in the measurement strategies, particularly in the area of student tracking, it is imperative to involve administrators early on in the process of developing an integrated approach to the assessment activities.
