Chronic absenteeism rate
Intended to hold the state's chronic-absenteeism rate; the column is empty for individual Philadelphia schools in the state file, so no cells are served and the metric is hidden from dropdowns.
Measured in percent; lower is better (percentiles are flipped so a high percentile is always good).
