The two schools serve the same grades (6–08) but at sharply different scales. Harrison Park School enrolls 321 students to Kellogg Middle School's 677 — roughly half the headcount — and that size difference shows up directly in classroom density. Harrison Park School's student-teacher ratio is 13.4:1, compared to 16.1:1 at Kellogg Middle School, meaning Harrison Park School students have on average one additional teacher for roughly every three students relative to their peers across town. Free and reduced-price lunch eligibility is nearly identical: 64% at Harrison Park School and 65% at Kellogg Middle School, so both schools serve similarly high-need populations and cannot be separated on that dimension.

Both schools operate grades 6–08, so families won't gain or lose a grade level by choosing one over the other. The structural difference that remains is scale: Harrison Park School is a smaller, more intimate environment with tighter student-teacher ratios and a slightly stronger academic score, while Kellogg Middle School offers a larger campus with marginally superior growth momentum — suggesting its instructional model is effective at accelerating students who may enter with gaps.
