Summary

Poison Spider Elementary serves 190 students in grades K–8 in Casper, in Natrona County School District #1. Its 2025–26 results show a sharp difference between subjects: English language arts (ELA) is comparatively stronger, while mathematics is the clearest concern. The school averaged 30% proficient in math across grades 3–8, compared with 58% statewide and 55% districtwide—a 28-point gap below the state.

ELA is a relative strength, although results vary by grade. In 2025–26, grade 5 students were 70% proficient and grade 6 students were 68%, above both state and district averages in those grades. Across all six tested grades, the school averaged 53% in ELA, about 5 points below the state and 2 points below the district. Math was weaker across the board: no tested grade reached its state average, and in shared grades 3–5, Poison Spider averaged 31% compared with 63% across nine nearby same-district schools—the lowest result among the ten schools compared.

ELA has improved over time, but math has not: the ELA average rose 18 points from 2022–23 to 2025–26, while the math average fell 2 points, and its gap below the state widened from 20 to 28 points. SchoolDigger gives the school a 15th-percentile ranking and 1 star for 2025–26; it ranks second-lowest among the nine nearby same-district schools, whose percentiles range from 6 to 78. The school’s 2024–25 student-teacher ratio was 13.5, and 53% of students were free/reduced lunch eligible, compared with a 48% average at the nearby schools. One notable older result: SchoolDigger ranked the school’s effectiveness for Special Education Students at the 86th percentile in 2020–21, versus the school’s overall 20th percentile that year; this is a single-year finding, and small enrollment can make grade-level results fluctuate.

My son loved his time at Poison Spider! He benefited from the small class sizes family oriented atmosphere. Students are known at PS, not just by their teacher, but by all staff. He was very prepared for middle school. Close Quote
