Summary:
ZIP code 99159 has one elementary school, P C Jantz Elementary in Odessa, serving students from Pre-K through sixth grade. The school enrolls 121 students and is part of the Odessa School District. Its 13:1 student-teacher ratio suggests a relatively small learning environment, while 42.98% of students qualified for free or reduced-price lunch in 2024–25. Because it is the only elementary school in the ZIP code, families cannot compare it with another nearby school in the same area using this data.
Academic results are mixed, with math standing out as the school’s strongest current area. In 2025–26, 45.59% of students demonstrated proficiency in math, slightly higher than both the district rate of 42.48% and the Washington rate of 43.11%. Math also improved substantially from 35.94% the previous year. However, performance varied considerably by grade: fourth-grade math proficiency was 50%, compared with only 28.57% in fifth grade and 26.32% in sixth grade. English language arts proficiency was 47.06%, higher than the district’s 45.13% but below the statewide rate of 52.81%. School ELA results were below the state in fourth, fifth, and sixth grades, with fifth grade showing the largest gap.
Science results improved notably, rising from 30.43% to 42.86% year over year, but remained below both the district’s 47.73% and the state’s 50.95%. The clearest pattern for parents to investigate is the transition from fourth to fifth grade, when both math and ELA results appear relatively weak. The school’s statewide ranking also declined from the 54th percentile in 2023–24 to the 41st percentile in 2025–26, despite recent gains in math and science. Because the school is small, results can shift noticeably from year to year depending on the performance of individual student groups, and suppressed third-grade scores cannot be interpreted as low performance.
