Horizon Science Academy Dayton Downtown

Public, Charter Grades K-8

1416^th

SchoolDigger Rank ?

of 1,560 Ohio Elementary Schools

Better than 9% of Ohio elementary schools

Summary

Horizon Science Academy Dayton Downtown is a small K–8 charter school at 121 S Monmouth St. in Dayton, Ohio, enrolling 188 students in 2025–2026 and reporting as its own district. It is much smaller than nearby K–8 schools such as Emerson Academy (674 students) and Pathway School of Discovery (843), and closer in size to City Day Community School (170).

By state measures, the school sits near the bottom: a statewide rank of 1,416 of 1,560 (9th percentile, 0 stars) and a district rank of 742 of 773. Chronic absenteeism is 59.3% — the highest among nearby schools and far above River's Edge Montessori Elementary School (12.0%) and Pathway (21.1%). Test scores are low in most grades; an unweighted average of its reported grade-level proficiency rates is about 18.6%, compared with roughly 57.3% at Pathway and 42.9% at Emerson. Math is the weakest area, ranging from 0% to 22.7% across grades and well below state averages. Eighth grade is especially difficult: 0% in math, 0% in science, and 11.1% in ELA, versus 54.1% math at Pathway and 52.5% at Emerson.

There are bright spots. Fifth grade ELA was 59.1%, above every nearby school's reported rate, though still under the state's 70.4%. In the state's subgroup rankings, African American students placed at the 53rd percentile with 3 stars, the only shown subgroup at or above the state median. The student-teacher ratio of 17:1 is comparable to Emerson (17.3) and Pathway (16.9), and lower than several Dayton City schools. Because the school is small, individual grade results can swing widely, but the multi-year pattern shows math consistently weaker than ELA.

Great school. Staff is friendly and caring people. You can tell hands down that they are there for the right reasons. One of the best schools in the area. The teacher's go above and beyond to ensure that each child is given the chance to succeed. They even tutor children who need extra help after school. They ensue relationships with the family and keep them involved in the child's education. This is a plus in my book. I love knowing that my child's teacher is only a phone call or an email away to answer any questions or concern that I may have. Even after hours they are there. Small class sizes, college prep classes, loads of diversity and culture involved in this school, all people from all backgrounds attend you don't have to worry about your child not fitting in. Tons of after school activities, family nights held at school. Hands down the best school I have ever dealt with. Love it and would recommend it to anyone. They do a whole lot with very little. I will always be grateful for all the support and help they provide my daughter and myself when she first started school she had a hard time adjusting they went above and beyond. 4 years later I am just as happy with this school as when we started.
