Summary
Portales High is a 9–12 high school in Portales, New Mexico, serving 754 students as part of Portales Municipal Schools, a district where nearly all students are economically disadvantaged. In 2025–2026, the school ranked 91st of 132 New Mexico high schools—31st percentile, 2 stars—down from 2021–2022 through 2023–2024, when it was a mid-pack 3-star school around the 50th–55th percentile. Its district is also below average, ranked 61st of 87 districts (30th percentile, 2 stars).
Academically, Portales High’s 2025–2026 11th-grade proficiency rates were below New Mexico averages in every reported subject: 30.56% in language arts vs. 36.78% statewide, 10.56% in math vs. 12.72%, and 23.89% in science vs. 34.02%. Nearby Clovis High outperformed Portales in every 11th-grade measure that year, including science at 33.94% and language arts at 34.11%. Much smaller Dora High was far higher—55.56% in language arts and 50% in both math and science—while Floyd High’s 11th-grade science score was 70%. By contrast, Portales’s 2024–2025 graduation rate was a relative strength at 91.9%, above the state’s 80.6% and Clovis High’s 81.3%, though prior years were lower (72.4% in 2023–2024 and 75.4% in 2022–2023).
Context matters: Portales High’s free/reduced-lunch rate reached 99.73%, compared with 83% at Clovis High, 85% at Floyd High, and 45.74% at Dora High. Its 2024–2025 student-teacher ratio was 15.5—better than Clovis High’s 17.7 but far above Dora High’s 5.6 and Floyd High’s 4.1; the 2023–2024 ratio of 114 appears to be a data anomaly. The most pressing signal is subgroup performance: low-income students ranked 88th of 89 schools (1st percentile, 0 stars) in 2025–2026, a steep drop from 58th percentile and 3 stars in 2023–2024. Overall, Portales High combines a strong recent graduation rate with below-average proficiency, a two-year drop to 2 stars, and severe challenges for its low-income students.
