Platte County School District #2

Platte County School District #2 has three schools serving kindergarten through grade 12 in the Guernsey-Sunrise area: Guernsey-Sunrise Elementary (96 students), Guernsey-Sunrise Junior High (35), and Guernsey-Sunrise High School (59). The main takeaway is that most recent proficiency results are below state rates: 16 of 19 school-grade-subject results were lower, with middle-school ELA and math closest to state levels.

Guernsey-Sunrise Junior High stands out most consistently in ELA and math, averaging 56.1% and 49.6% proficient, compared with state averages of 58.7% and 53.4%. Its grade 8 math result was above the state rate, 55.6% versus 53.9%. Results are more uneven at the other schools: Guernsey-Sunrise Elementary averaged under 34.5% in ELA and 39.5% in math, while Guernsey-Sunrise High School averaged 35.7% in both subjects. Each school has a notable exception: Elementary grade 5 scored 58.3% in ELA and math; High School grade 10 math scored 50%, five points above the state rate. Science is a broader concern, with all three schools’ current results below their corresponding state benchmarks.

ELA and math results moved closer to state rates overall between 2024–2025 and 2025–2026, but science moved farther away: the average science gap widened from 9.8 to 19.4 percentage points. SchoolDigger rankings improved for all three schools; Junior High rose from the 8th to the 30th percentile, Elementary from the 5th to the 13th, and High School from the 16th to the 21st. These ranking gains did not prevent declines in science at each school’s comparable tested grade. High School grade 10 math improved from 33.3% to 50%, and its 2024–2025 graduation rate was 84.2%, slightly above the state’s 83.1%. The schools’ 2024–2025 student-teacher ratios ranged from 6.9 to 8.7, and reported free/reduced-lunch eligibility was similar, from 57.1% to 59.4%; these are useful context, not explanations of results.
