As context, free/reduced lunch eligible figures for school year 2021–22 ranged from 1% at South Park to 3% at Deerfield High; these figures do not explain score differences. Ratios also do not line up simply with results: South Park’s is 12.0 students per teacher, compared with 11.1 at Wilmot, despite South Park’s stronger school-level results.
