Best Elementary Schools in Zip Code 86504

ZIP code 86504 has two elementary schools in Window Rock Unified District: Tsehootsooi Primary Learning Center, serving kindergarten through grade 3 with 430 students, and Tsehootsooi Dine Bi'Olta, serving kindergarten through grade 6 with 64 students. The most striking finding is the wide gap in reported all-grades ELA proficiency: Dine Bi'Olta is at 43%, while Primary Learning Center is at 25%—an 18-point difference.

On ELA, Dine Bi'Olta stands out above the state benchmark, while Primary Learning Center is below it: their scores are 2 points above and 16 points below the state’s 41%, respectively. The two-school average is 34%, or 7 points below the state; this is an unweighted average, not a student-weighted area result. In math, Primary Learning Center reports 23% proficiency, 10 points below the state’s 33% and 5 points above the district’s 18%. Dine Bi'Olta’s math result is suppressed, so the available figures do not show which school performs better in that subject.

Dine Bi'Olta’s SchoolDigger ranking improved over time: its percentile rose from 22 in 2017–2018 to 25 in 2021–2022 and 42 in 2022–2023, when its rating also rose from one star to two. That improvement reflects relative ranking, not a demonstrated rise in proficiency. Dine Bi'Olta also has a lower student-teacher ratio (12.8 versus 15.3) and higher reported spending per student ($23,571 versus $17,084); these differences do not explain the score gap, and the schools serve different grade spans. School-level math and some grade-level scores are suppressed, and free/reduced-lunch rates are not supplied.
