Why this matters
Chronic absenteeism — missing 10%+ of school days — is the single strongest predictor of dropout risk and low achievement. Unlike suspensions (which affect a few students deeply), chronic absence is a diffuse problem affecting 1 in 4 US students post-pandemic. A steady multi-year decline signals strong family engagement; a flat line near the US average is the new normal but still a concern.
What we're seeing
At ARLINGTON H S, chronic absenteeism has fallen 4% over the 5-year window — from 16.6% in 2015 to 15.9% in 2020. Despite that, the gap vs US average of ~28% has actually widened — from 11.4% below in 2015 to 12.1% below in 2020.
