I found it interesting that a number of schools are well below capacity. Cherokee middle school is at 74% of capacity while nearby Hamilton is at 106%. Hamilton’s free and reduced lunch population is just 18% while Cherokee’s is 60% (!) Details.
The District is planning to raise property taxes via a spring, 2015 referendum. Said referendum, if passed would expand Hamilton Middle School (“four additional classrooms”), among others. This is quite remarkable with available capacity at nearby Cherokee.
