EdLight Predicts a Year of Learning on State Tests
EdLight's uniform scores are a stronger predictor of end-of-year state test performance than traditional course grades. A gain in EdLight scores is associated with a change in test performance roughly four times greater than the achievement gap between high- and low-income students.
Using More Strategies Leads to Higher Test Scores
Students who use a diverse approach—combining visual, computational, and written strategies—score higher on end-of-year tests. The assignment's design drives strategy use more than the teacher's style, showing the value of curriculum.
Specific Error Tags Close Racial & EL Achievement Gaps
By pinpointing the type of mistake, EdLight data helps explain why students struggle. Adding misconception data eliminates the observed score gaps for English Learners, Black, and Hispanic students.
Not Finishing the Work is a Bigger Risk Than Errors
Incomplete assignments are the biggest negative predictor of end-of-year test scores. On the flip side, students with Precision Errors tend to have higher test scores, suggesting they are quick fixes that don't reflect deeper learning gaps.
