Student retention rate

Student retention rate measures the percentage of students who re-enroll from one term to the next, most commonly tracked as first-to-second-year retention at colleges and universities, though it is also used at the course and program level. It is the education-sector counterpart to churn rate in subscription businesses: a high churn equivalent means the institution is failing to keep students it originally enrolled.

The typical formula is students who re-enrolled in the following period / students enrolled in the starting period × 100, usually calculated per entering cohort analysis group, such as the fall first-year class, rather than across the whole student body at once, since mixing cohorts of different tenure would obscure the actual trend. It is distinct from graduation rate, which tracks completion over a much longer, multi-year horizon and allows for students who pause and later return.

Institutions track retention rate as a core measure of student success and financial sustainability, since recruiting a new student is typically far more costly than retaining an enrolled one, and it is a common reporting metric to accreditors and boards. learning analytics systems increasingly build attrition risk scores from engagement and academic data to flag students likely to leave before the next enrollment period, so advisors can intervene while there is still time to act, rather than learning about the drop only after the fact.
