Summary:
ZIP code 89403 covers Dayton, Nevada, in the Lyon school district, and it has five schools serving students from elementary through high school: three elementary schools (Riverview Elementary School, Dayton Elementary School, and Sutro Elementary School), one middle school (Dayton Intermediate School), and one high school (Dayton High School), with 2,433 students enrolled in total. The district context matters: Lyon is ranked 10th of 12 districts in Nevada, at the 17th percentile with a 1-star rating, and four of the five local schools currently carry 1 star. Only Dayton Elementary School currently carries 2 stars.
Dayton Elementary School has the strongest current profile in the ZIP: the only 2-star rating, the highest current rank at 236 of 376 (37th percentile), the best all-grades reading proficiency among elementary and middle schools at 41.7%, and chronic absenteeism of 20.1%, below both district and state levels. Riverview Elementary School has the lowest chronic absenteeism in the ZIP at 18.2%, though its achievement remains modest. Sutro Elementary School posts strong 3rd-grade results (50% reading, 44% math) but higher absenteeism of 33.3%. Dayton High School stands out for a 91.7% graduation rate, above district 85.7% and state 85.4%.
Several shared weaknesses are worth knowing. No elementary or middle school reaches the state average in math or reading, and elementary math is a broad gap — Dayton Intermediate School is the lowest at 20.0% math and 27.8% reading. Dayton High School has low test proficiency relative to the state and chronic absenteeism of 36.9%, plus the lowest per-student spending ($11,810) and highest student-teacher ratio (22.4) in the group. Four schools report 100% free/reduced lunch; Dayton High School's figure is not reported. Elementary science results are suppressed by the state and should be treated as unknown.
