Summary:
There are two public elementary schools serving zip code 83644 in Middleton, Idaho, both part of the Middleton District and both serving grades PK-5. Middleton Mill Creek Elementary is the stronger overall performer, ranking 68th out of 346 Idaho elementary schools with a 4-star rating, while Middleton Heights Elementary ranks 127th with a 3-star rating. Mill Creek leads Heights by roughly 10 percentage points in both all-grades math (62.4% vs. 52.3%) and all-grades ELA (65.6% vs. 55.9%) for 2025–26. Mill Creek is also more consistent across grade levels, with no weak clusters, while Heights shows a notable pattern of lower 3rd-grade scores but excellent 5th-grade results—especially in science (63.4% vs. Mill Creek’s 48.3%) and ELA (71.1% vs. 68.5%).
Heights serves a higher-need population, with 38.1% of students eligible for free/reduced lunch compared to 27.4% at Mill Creek, a 10.7-point difference that provides important context for test scores. Both schools struggle with chronic absenteeism, however, with rates around 18.5–19.0% versus the state average of 13.8%, meaning roughly one in five students at each school misses too much school. Spending per student does not explain the performance gap—Heights actually spends $283 more per student than Mill Creek ($6,678 vs. $6,395), though that data is from 2018–19 and may not reflect current resources.
Despite their differences, both schools are above-average options compared to Idaho state averages. Mill Creek exceeds state proficiency by about 19 points in math and 11 points in ELA, while Heights also beats state averages in math (52.3% vs. 43.1%) and nearly matches in ELA (55.9% vs. 54.0%). Families in this zip code have two solid choices: Mill Creek for overall consistency and top-tier academic performance, or Heights for a school that appears to help students finish elementary school strong, especially in science and upper-grade literacy.
