Summary:
ZIP code 55442 has one listed public school, Zachary Lane Elementary, an elementary school serving grades K–5 in Plymouth, MN, in Robbinsdale Public School District. It enrolls 428 students; there are no middle, high, or alternative public schools in the ZIP. In 2025–2026, it outperformed its district in all-grades math (52% vs. 26.9%), reading (54% vs. 38.5%), and science (26.6% vs. 16.1%), and it was above state averages in all three. Its rank is 339 of 869 (61st percentile, 3 stars), while the district is ranked 335 of 458 (27th percentile, 1 star).
Reading is the most consistent strength: every tested grade—3rd, 4th, and 5th—exceeds district and state averages, and all-grades reading is 54% vs. 48.6% state. Math is strong overall (52% vs. 44.9% state) but uneven: 3rd-grade math is 51.4% vs. 57.9% state, the only reported metric below state; 4th-grade math is the strongest score at 60.6%; 5th-grade math is 43.8% vs. 41.9% state. Science is the weakest absolute subject at 26.6% proficient, reported only for 5th grade, though still above district 17.1% and state 25.9%. The school has a 39.49% free/reduced lunch rate and a 14.9 student-teacher ratio, implying about 29 teachers.
The main warning sign is the recent downward trend. The school’s rank percentile fell from 73 in 2023–2024 to 72 in 2024–2025 to 61 in 2025–2026, and its star rating dropped from 4 stars to 3 stars. Test scores declined in every subject from 2024–2025 to 2025–2026: math went from 56.37% to 52%, reading from 62.14% to 54%, and science from 42.11% to 26.6%. Its advantage over the state narrowed in math (+11.16 to +7.1), reading (+12.55 to +5.4), and science (+15.96 to +1.1). Its advantage over the district also shrank in all three subjects. Overall, the school remains above its district and slightly above the state in 2025–2026, with reading as its clearest strength, but the decline in rank and proficiency—especially the sharp science drop—is the key concern for parents to watch.
