Summary:
Zip code 75082 in Richardson, Texas, is home to three elementary schools—Stinson Elementary, Schell Elementary, and Miller Elementary—all part of the highly rated Plano Independent School District (Isd), serving grades K-5 with a combined enrollment of about 1,181 students.
Among these schools, Schell Elementary stands out as the most consistent performer, maintaining a 4-star rating for three consecutive years and holding the highest current state ranking at the 78th percentile. In contrast, Stinson Elementary was the academic leader with a 96th percentile ranking in 2023-2024, but its 2025-2026 scores dropped sharply, causing its ranking to fall to the 62nd percentile—a notable "Stinson Slide" that parents should investigate. Miller Elementary spends the most per student at $11,293, yet it has the lowest current ranking (59th percentile) and shows volatile test scores, suggesting higher spending does not guarantee better outcomes. All three schools have favorable student-teacher ratios (12.2:1 to 13.1:1) and strong 5th-grade science scores, significantly outperforming the state average of 29.57%.
Key takeaways include the spending-versus-performance paradox at Miller, where extra resources don't translate to consistent academic results, and the importance of looking beyond overall rankings to individual grade-level performance—for instance, Miller's 5th-grade class excelled in 2024-2025 while its 4th-grade class struggled. Parents should also note that Schell Elementary serves the highest percentage of students on free/reduced lunch (33%), yet delivers stable, above-average results, while Stinson Elementary’s recent decline highlights how a single cohort can shift a school's profile dramatically.
