What we can't show
  • — Growth data isn't available — the state needs matched grades across years to compute it.
  • — Scored here as an elementary school — other grade spans appear in the data appendix.
  • — Low-income students here trail the state average for their group by 21 points in ELA — worth asking how the school is closing that gap.
