What stands out at Brentano Elem Math & Science Acad
Large campus carrying a heavier staffing load
Brentano Elem Math & Science Acad is larger than most Illinois schools and also reports more students per teacher than the state norm. Those facts reinforce one another: this is not merely a small specialist campus whose ratio is distorted by a tiny denominator. The operational constraint is scale paired with tighter staffing. Families comparing programs should inspect whether counselors, gifted access, and other support indicators compensate for that teacher-staffing load.
Counselor caseload is the clearest capacity constraint
Brentano Elem Math & Science Acad reports roughly 763 students for each counselor, well beyond the ASCA-recommended 250:1 benchmark. Unlike total teacher staffing, that measure speaks specifically to academic planning, crisis response, and student guidance; a middle-range Resource Investment Index can conceal the bottleneck. The ratio is calculated from federal full-time-equivalent staffing and does not show how the district shares counselors across buildings or schedules their time.
