What is an early-warning system?
Definition
EvidenceEarly-warning system
An early-warning system uses data such as attendance, grades and behavior to flag students who may need support.
Why it matters for schools
Results are mixed. In a trial in 73 high schools, chronic absence was 10% against 14% and course failure 21% against 26%, with no change in low GPA, suspensions or credits. Wisconsin's dropout system was wrong about 74% of the time when it predicted a student would not graduate on time, with higher false-alarm rates for Black and Hispanic students, and the label had no significant effect on graduation. AI tools that flag students inherit the same risks.

Questions and answers
Do early-warning systems work?
Mixed: one trial reduced chronic absence and course failure but not low GPA, suspensions or credits.
Can student risk labels be biased?
Yes. Wisconsin's system had higher false-alarm rates for Black and Hispanic students.
What does this mean for AI that flags students?
Treat flags as hypotheses, put a person in the loop, and check false flags by group.
