Data from the National Center for Education Statistics. Stress scores measure the amount of financial pressure on an institution. Alert and warning thresholds are based on rate of change in each metric* from 2009-10 to 2016-17 for the lowest 20th and 10th percentiles, respectively, of schools in the sector. One red bar indicates the projected value for 2019-20 would reach the alert threshold; two red bars indicates the projected value would fall below the alert threshold; three red bars indicates the projected value would fall below the warning threshold. *Retention thresholds calculated based on 2016-17 percentage alone.
