Summary:
Zip code 77089 in Houston, Texas, is home to two high schools serving grades 9-12: Dobie High School and Clear Horizons Early College High School, which represent vastly different educational models and performance levels within the same geographic area.
Clear Horizons Early College High School is the standout school in this area, ranking in the 98th percentile statewide (41st out of 2,009 high schools) for the 2025-2026 school year. This small, specialized school within the Clear Creek Independent School District (Isd) achieves near-perfect results, with a 99% graduation rate and proficiency rates dramatically exceeding state averages—for example, 99.15% of students are proficient in English II Reading compared to the state average of 59.88%. In contrast, Dobie High School is a large, traditional public school in the Pasadena Independent School District (Isd) with 3,692 students.
