Calvin Nelms Charter Schools, TX

Original Research by School Decision on Calvin Nelms Charter Schools

Calvin Nelms Charter Schools is a small charter district serving grades six through twelve in Harris County, with enrollment concentrated in the middle school years. The district operates two schools: a middle school and a high school, serving a student body that is majority Hispanic, with substantial Black and Asian enrollment and smaller representation from other backgrounds.

On the most recent state assessment data, the district shows uneven performance across subjects and grade levels. In English language arts, proficiency runs moderately strong across grades six through eight, holding around the mid-range. Mathematics proficiency is mixed: sixth-grade performance sits at a lower level, seventh grade improves noticeably, and eighth grade drops significantly below both. Science proficiency in eighth grade is strong, but social studies proficiency in the same grade is very low, a notable gap that a parent may want to look into further with the school. Overall, the district's proficiency index across all tested subjects and grades places it in the top quartile among Harris County's districts, a positioning that reflects strength in reading and science balanced against weakness in social studies and the mathematics dip in middle grades.

Chronic absenteeism at the district is also in the top quartile for the county, meaning attendance is notably better than the typical Harris County district. Per-pupil current spending is in the lower range for the county, so the district operates with less funding per student than the county median.

The district's enrollment is small enough that year-to-year trend data is not available. Free-or-reduced-price-lunch status, special education identification, and English learner counts were not reported in the available data. The attendance data and academic results are reported; graduation rate data was not available, likely because the high school cohort is small and state graduation metrics may not yet apply or may not be separately reported for a very small cohort.

For a family considering this charter, the profile is a selective-admission or merit-focused environment with a small, stable middle and high school cohort. The strong proficiency index and low absenteeism suggest engaged families and students. The social studies weakness in eighth grade and the math drop-off in that same grade are areas worth understanding in depth with the school to determine whether they reflect curriculum focus, assessment difficulty, student population shifts, or other factors. Per-pupil spending is lean, which typically affects the breadth of electives, arts, career pathways, and support services available.
