Summary:
Zip code 78023 in Helotes, Texas, is served by a single high school, O'Connor High School, which educates students in grades 9 through 12 and is part of the Northside Independent School District (Isd).
O'Connor High School is a standout institution, consistently earning a 4-star rating from SchoolDigger and ranking in the top 12-13% of all Texas high schools. With an enrollment of 2,535 students, the school significantly outperforms its district in every academic metric. For the 2025-2026 school year, STAAR EOC proficiency rates were notably high: 86.68% in Biology, 86.45% in U.S. History, 77.97% in English II Reading, 73.72% in English I Reading, and 65.97% in Algebra I. The school also boasts a 97.8% graduation rate and a low 0.6% dropout rate, both better than the district averages. The student-teacher ratio is 17.1:1, and spending per student is $8,026.
A key takeaway is the school's consistent academic dominance, particularly in science and history, where proficiency rates have remained above 82% for two consecutive years. However, Algebra I presents a relative challenge, with a 65.97% proficiency rate that, while above state and district averages, lags behind the school's other subjects. The school's low free/reduced lunch rate of 23.39% provides important context for its high performance, and its efficient use of resources—achieving results far above the state average with a spending per student of $8,026—marks it as a high-value institution within the district.
