Summary
Harmony Science Academy - Plano is a public charter elementary school in Plano, TX, serving 627 students in grades PK-5 and has shown a remarkable turnaround, climbing from a 2-star rating to a 4-star rating in recent years. This school stands out for its exceptional ability to help students from low-income backgrounds achieve high academic results, ranking in the 94th percentile statewide for this group in the 2025-2026 school year. This is a significant achievement, especially when compared to nearby high-performing schools like Centennial Elementary, which serves a much smaller percentage of students from low-income families. Harmony Science Academy also delivers outstanding results for its African American students, ranking in the 96th percentile, a clear differentiator from many other schools in the area.
The school operates with a lean and efficient model, spending less per student ($9,958) than nearby Plano Independent School District (Isd) schools like Davis Elementary ($12,556) and Weatherford Elementary ($14,175), while also having a higher student-teacher ratio (17.6:1). This suggests the school is getting strong results with fewer resources.

While the school is a powerhouse for certain groups, its performance is not uniform across all students. For instance, Hispanic students ranked in the 45th percentile in 2025-2026, a notable drop from the previous year. Additionally, there is a growing gap between male and female students, with girls ranking in the 89th percentile and boys in the 68th percentile.
