Cohort Analysis - MIS Application

  1. 1. COHORT ANALYSIS Alfred Mutanga MIS Specialist University of Venda Date: 22 November 2013 Venue: NWU PUK Sports Village
  2. 2. Why a Cohort Analysis? ???? A cohort? – A group of students selected for further study • Meets a certain predetermined criterion • Often this a group of students enrolling for the first time in a cluster together during the same academic period – Baseline data: is the basis for cohort study
  3. 3. Baseline Data Baselines • Established with internal data and are used to determine performance over time – These data are used to represent the state of the issue at hand before selected activities or events took place – Establishment of baselines is critical for continuous quality improvement initiatives or other improvement processes • Cohort Analysis refers to the use of data by institutions to compare current performances with a prior performance to determine trends
  4. 4. Theoretical Framework for Cohort Analysis The Persistence- Retention- Attrition Triad? – Refers to the tendency for students to continue their enrollment at an institution – Persistence focuses on the tendency of students to continue their enrolment from semester to semester – Retention Studies focuses on the tendency for the students to enroll in consecutive semesters – Attrition relates to the tendency of the students to withdraw from a qualification Persistence- Retention- Attrition how is HEDA taking care of this through Cohort Analysis?
  5. 5. Persistence-Retention-Attrition: HEDA Contexts • Persistence: HEDA includes Enrolment Studies in the Cohort Analysis Application • Enrolment Studies is an examination of the number of students enrolled for an academic period tracked year by year • Persistence studies may include: – Study of Graduation rates – The Flow of students through the institution • Data from these studies may become baseline for determining the impact of student retention-enhancing programs or activities
  6. 6. Retention • Qualification Retention- tendency for students to continue attending a qualification until completion regardless of the grade they receive • Usefulness of Retention Studies: – Show students’ overall determination to stay enrolled regardless of grade – Highlight the patterns of student withdrawal from qualifications
  7. 7. Attrition Attrition in HEDA is defined with two indicators and these are drop-outs and Stop-outs • This type of study is a variation of the aforementioned studies as it focuses on the persistence through a semester or an academic year. • Stop-outs are students who withdraw from a qualification and at a later date re-join the qualification (or another at the same institution?) • Drop-outs are students who withdraw from a qualification and will never re-join the qualification during the period of study • Calculating attrition is an important aspect of determining student engagement with the institution
  8. 8. A Snapshot of Results of Cohort Analysis
  9. 9. Cohort Analysis Provoke Some Questions • Graduates in the first Cohort Year-how come we have a graduate during the first year students enrol for a qualification? Methodology FCE • Student Unit Records– Who are the students who are retained in the system for such a long time? – Are we doing enough as an institution to help students graduate in record time or finish their courses? – What do our Teaching and Learning, Assessment say? Do they need to be reviewed • Premise for Institutional Research activities concerning student engagement with the institution, etc.
