How Astronaut Jose' M. Hernandez Academy compares with California and U.S. medians
What stands out at Astronaut Jose' M. Hernandez Academy
Small campus with unusually lean teacher staffing
Astronaut Jose' M. Hernandez Academy sits near the smaller end of the California enrollment distribution while also reporting a lower student-teacher ratio than most state schools. That pairing is consistent with a compact, teacher-dense setting, though small scale can limit the number of specialized courses or support roles a campus can sustain. The program and staffing sections below show whether the lean ratio extends beyond classroom teachers into broader student services.
Higher need meets a leaner resource profile
Astronaut Jose' M. Hernandez Academy combines above-typical economic need with a Resource Investment Index in the lower part of the California distribution. This is the page's clearest equity tension: the population indicated by free-meal eligibility may require more support, while the reported staffing, counselor, gifted-program, and attendance inputs produce a comparatively lean composite. The index is not an academic grade, but the mismatch is a concrete reason to inspect each component closely.
Attendance is the dominant support signal
Astronaut Jose' M. Hernandez Academy's 28.5% 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.
