Summary:
ZIP code 57225 has two elementary schools: Clark Elementary - 02, serving PK–5, and Silver Lake Colony - 07, serving K–8. Their reported 2025–26 results show a sharply divided picture, especially in mathematics. The most important finding is that Clark’s proficiency rates were substantially higher than Silver Lake Colony’s in both reported all-grades subjects.
Clark stands out at the top: in 2025–26, 60% of students were proficient in ELA and 57% in mathematics, compared with 33% and 8% at Silver Lake Colony. That is a 27-point gap in ELA and a 49-point gap in mathematics. Clark was also above the state rates by 11 points in ELA and 13 points in mathematics, while Silver Lake Colony was below the state by 16 and 36 points, respectively. Clark’s grade-specific results were above state rates in every reported grade and subject, with its strongest margins in fourth grade: 26 points in ELA and 19 in mathematics.
The schools’ results moved in opposite directions from 2024–25 to 2025–26: Clark gained 5 points in ELA and 7 in mathematics, while Silver Lake Colony fell 10 points in ELA and 13 in mathematics. SchoolDigger gives Clark four stars and ranks it 59th of 203 schools, at the 71st percentile; its listed percentile rose from 55 in 2023–24 to 61 in 2024–25. Silver Lake Colony was at the 37th percentile in 2024–25, with no 2025–26 rank supplied. Other school profiles differ too: in 2024–25, Clark’s student–teacher ratio was 12.1 and 26% of students were free/reduced lunch eligible, compared with a ratio of 8 and 81% eligible at Silver Lake Colony. These are contextual differences, not explanations for test results. Silver Lake Colony enrolls just 16 students, and the schools serve different grade spans, so their all-grades results are not perfectly matched comparisons.
