Summary
Guyer High School is a large, high-performing public high school in Denton, TX, serving 2,577 students in grades 9-12 as part of the Denton Independent School District (Isd).
Guyer consistently earns a 4-star rating and ranks among the top 15-20% of Texas high schools, with an exceptionally low student-to-teacher ratio of 15:1. Its graduation rate has hovered between 98.8% and 99.5% for the last five years, and its dropout rate has been 0.0% or 0.1% during that same period. This performance dramatically outpaces its direct district peer, Ryan High School, which has dropped to a 2-star rating. For example, in recent test scores, Guyer’s proficiency in Biology (76.88%) and U.S. History (79.85%) far exceeds Ryan’s (64.84% and 63.03%, respectively). However, Guyer faces a clear "Guyer Gap" when compared to top-tier schools in neighboring districts, such as Flower Mound High School and Argyle High School, both 5-star schools that achieve higher proficiency in subjects like English II Reading (88.30% and 87.25% vs. Guyer’s 69.36%).
While Guyer excels for its general population, recent data reveals challenges in supporting specific student groups. In the 2025-2026 school year, performance for Hispanic students, low socio-economic status students, and English Language Learners dropped to 2-star or 1-star ratings. Additionally, Algebra I is a persistent weak point, with only 32.78% of students proficient, well below the state average of 54.03%. On a positive note, Guyer operates with remarkable efficiency, spending $9,755 per student—less than Ryan High School ($10,476) and far less than alternative schools like Fred Moore High School ($19,114)—while achieving superior academic results.
