Summary:
Tranquillity has two schools in Golden Plains Unified: Tranquillity Elementary serves kindergarten through grade 8, and Tranquillity High serves grades 9–12; no middle school is listed. The schools enroll 209 and 370 students, respectively. In 2025–26, both schools’ reported all-grades proficiency was below state results in English language arts, math and science, with the largest shortfalls in science.
Tranquillity High had the higher reported all-grades results: 40% in English, 31% in math and 19% in science, compared with 23%, 16% and 8% at Tranquillity Elementary. Those differences are 17, 15 and 10 percentage points, respectively, though the schools serve different grade spans. High’s grade 11 math result, 31%, was close to the state’s 32%; its graduation rate was 99% and dropout rate was 0%. However, its chronic absenteeism was 29%, compared with 18% at Elementary and 18% statewide. Elementary’s brighter grade-level results were in English for grades 4–6: its scores exceeded district results by 11, 3 and 8 percentage points, respectively, but remained below state results.
Recent results show mixed progress: the simple average of the two schools’ scores rose from 15% to 24% in math and from 5% to 14% in science between 2024–25 and 2025–26, while English fell from 38% to 32%. SchoolDigger’s statewide percentile improved from 19 to 42 for High and from 8 to 11 for Elementary; their star ratings rose from 1 to 2 and from 0 to 1. The 2024–25 student–teacher ratios were 14.4 at High and 16.3 at Elementary. High’s low-income measure was 54% directly certified for free meals, school year 2024–25; Elementary’s was 88% free/reduced lunch eligible, school year 2024–25. These are different measures and should not be directly compared. The school-to-school score comparisons are descriptive, not grade-matched.
