Horizon Science Academy-denison Middle School, Cleveland OH

Original Research by School Decision on Horizon Science Academy-denison Middle School

Horizon Science Academy-Denison Middle School is a kindergarten-through-eighth-grade charter school located on Denison Avenue in Cleveland. The school serves a small enrollment with a predominantly Black student population, alongside a substantial Hispanic enrollment and smaller shares of white, multiracial, and Asian students. Specific free-or-reduced-price lunch rates and special-population counts were not available in the data.

The school's academic performance on Ohio's state tests shows areas that parents should examine closely. Across grades three through eight, proficiency in English language arts and math sits in the low range, with roughly a third of tested students meeting state standards in each subject. Science proficiency is notably lower. When positioned against other districts in Cuyahoga County, the school's overall proficiency index places it in the bottom quartile. The most recent comparison data available comes from 2024-25 for math and ELA and older testing results for science and social studies. A parent may want to look into the school's specific interventions and support structures in core academics with the school directly, especially given these proficiency levels.

Graduation rate data and chronic absenteeism metrics were not available, which reflects the school's grade configuration; the school does not serve high school grades and therefore does not report a four-year graduation rate.

The school is part of Horizon Science Academy-Denison Middle School, a single-school charter district. The name and structure indicate a science focus, though specific program details beyond this designation were not provided in the available data. The school's website, course catalogs, and detailed program documentation would offer clearer pictures of curriculum emphasis, enrichment offerings, and how the science focus is implemented in the classroom.

The housing market in the school's Cleveland zip code shows median home values somewhat below the state benchmark, with modest recent appreciation. Rental costs have risen at a faster clip. This context positions the school within a neighborhood with mixed economic stability.

No recent parent-relevant changes such as curriculum overhauls, staffing shifts or operational reorganizations with documented lasting impact were found in available sources. Parents interested in the school's direction and day-to-day operations should connect directly with school leadership.

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.
