Summary:
Zip code 93314 has five schools, from K–4 elementary grades through grades 9–12, with three elementary schools, one middle school, and one high school; enrollment ranges from 466 to 2,098. The 2025–26 results show schools performing differently by subject: all five were at or above the state in all-grades ELA, while Frontier High was below the state in math and science. The clearest takeaway is that no single school leads across every subject: Frontier stands out in ELA, while Del Rio Elementary leads in math and science.
Frontier High had the highest all-grades ELA result, 68%, about 19 percentage points above the state and 15 points above the other four schools’ average. But its math result was the lowest, at 32%—7 points below the state and 14 points below the other schools’ average; its 35% science result was also about 1 point below the state. Del Rio led in math at 50% and science at 55%, respectively 12 and 19 points above the state. Centennial Elementary was close behind Del Rio in math at 50% and led fourth-grade math at 57%, 15 points above the state. All-grades figures span different grades, so they are not like-grade comparisons.
Recent movement was mixed, and the average school advantage over the state narrowed in all three subjects from 2024–25 to 2025–26. The biggest reported gains were Del Rio science, up 8 points, and Centennial math, up 6; the largest declines were Rio Bravo-Greeley Elementary ELA, down 5 points, and Rio Bravo Elementary math, down 3. SchoolDigger rankings also diverged: Del Rio rose from the 68th to the 74th percentile between 2023–24 and 2025–26, while Frontier fell from the 80th to the 68th. As context, 2024–25 free/reduced lunch eligible shares ranged from 34% at Del Rio and Centennial to 51% at Rio Bravo-Greeley; Frontier’s student–teacher ratio was 26.0, compared with 19.0–21.9 at the elementary schools.
