How Chicago Technology Academy Hs compares with Illinois and U.S. medians
What stands out at Chicago Technology Academy Hs
Teacher staffing is the clearest operational strength
Chicago Technology Academy Hs's enrollment is not at an extreme, but its student-teacher ratio is: it reports fewer students per teacher than most Illinois schools. This is the most distinctive scale-adjusted signal in the federal record. It should be read as staffing capacity, not class size or an academic outcome; the page separately reports attendance, program access, demographics, and district finance so a single favorable ratio does not become an unsupported overall rating.
Attendance is the dominant support signal
Chicago Technology Academy Hs's 75.9% chronic-absence rate is more consequential than a generic staffing label: at least one quarter of students missed 10% or more of school days in the 2021-22 collection. That level can affect instruction, counseling demand, and continuity even when other reported resources look ordinary. The dataset records the scale of absence but not its causes, so it should prompt a current-year question rather than a conclusion about school management.
Chicago Technology Academy Hs is a mid-sized high school in Chicago, Illinois, enrolling 315 students.
Classes run notably small here: at 9.8:1, Chicago Technology Academy Hs is leaner than roughly 91% of Illinois schools and 30% under the state's 14:1 norm, more adult attention per pupil than most peers.
