Early warning indicators (education)

Data signals such as attendance and grades that flag students at risk of falling behind or dropping out.

Also called: early warning system, EWS, student risk indicators

Early warning indicators are measurable signals — attendance, course grades, behavior incidents, credit accumulation — that schools and districts track to identify students at elevated risk of disengagement or dropping out while there is still time to intervene. A widely cited framework groups these into "ABC" indicators (Attendance, Behavior, Course performance), reflecting research suggesting these three signals predict dropout more reliably than demographic factors alone.

An early warning system applies threshold rules or a predictive analytics model to these indicators, flagging a student once, for example, attendance falls below a set level or a course grade drops below passing, and routing that flag to a counselor for follow-up. This differs from a value-added model, which evaluates a teacher's or school's impact on outcomes after the fact; early warning indicators are forward-looking and operate at the individual student level.

Districts use these systems to prioritize limited counseling and tutoring resources rather than reacting after a student has already withdrawn. A documented pitfall is false positives eroding trust if thresholds are miscalibrated, and, as with any cohort analysis, indicators validated on one student population or school level do not automatically transfer to another without local recalibration — a separate concern from measuring course completion rate or student retention rate after the fact.
