Commack High School, Commack NY - Test Scores & Data

Original Research by School Decision on Commack High School

Commack High School is a regular public high school serving grades nine through twelve in the Commack Union Free School District. The school draws from a middle-to-upper-income residential hamlet in central Suffolk County, with a student body of roughly mid-sized enrollment distributed across all four high school grades.

The school's peer environment is predominantly white, with Asian, Hispanic, and other backgrounds represented in smaller shares. About a modest proportion of students qualify for free or reduced-price lunch, which aligns with the area's suburban, generally affluent character. The specific counts for English learners and students with IEPs were not available in the data provided.

State testing data was not available for this school, making direct comparison of academic proficiency impossible. The neighbor comparison fact-set for Suffolk County districts shows the school positioned in the bottom quartile on an overall proficiency index, but because the school reported zero students tested statewide in English language arts, mathematics, and science for the grade levels the state assesses, this ranking reflects data reporting rather than a measure of the school's instructional strength or college-preparation outcomes. A parent may want to look into the school's standardized testing practices and reporting with the district directly. The school does not have a four-year graduation rate in the available data; again, clarification with the district on graduation outcomes would be prudent.

One meaningful change relevant to college-bound families: Commack High School no longer assigns traditional class rank. Instead, transcripts use what the school calls Cohort Groups, a shift in how student standing is communicated to admissions offices. Families prioritizing class-rank visibility for competitive college applications should be aware of this practice.

The district's fiscal approach is disciplined. Over multiple recent years, including the budgets for 2023-24 and 2024-25, the Commack board has held its property tax levy increase to a restrained level, staying within the state-imposed cap while maintaining existing academic, social-emotional, and extracurricular programs and keeping class sizes stable. For homeowners weighing property tax burden, this reflects a conscious effort to manage costs without program cuts.

Commack itself is a mature, mostly built-out residential community spanning portions of the towns of Huntington and Smithtown, with an older, family-centered character. Median home values are substantial, reflecting a stable, established suburb rather than a boom-growth area. The commercial environment is dispersed along arterial corridors rather than clustered in a downtown; the place is car-dependent, with no Long Island Rail Road station and limited pedestrian walkability. Employers anchor in healthcare, education, and retail. The Commack Public Library and recreational parks serve as civic anchors, but civic and institutional life, like the schools themselves, is scattered across the hamlet rather than unified around a center.

Families in this school would typically be working professionals or retired, with multigenerational stability and above-average household incomes. The peer environment is suburban and relatively homogeneous. Without access to state proficiency data, current graduation figures, or detail on course breadth and advanced offerings, a parent should request from the school or district specifics on AP courses, dual-enrollment partnerships, career-technical pathways, college-placement outcomes, and supplementary testing data that might not flow through state reporting channels.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
