Schools in Seneca, Wisconsin are a small all-public system of three schools—Seneca Elementary for PK–5, Seneca Junior High for grades 6–8, and Seneca High for grades 9–12—all in the Seneca Area School District, which serves 255 students and is ranked 166 of 432 in Wisconsin (62nd percentile, 3 stars). Because the schools are small, a few students can move grade-level rates by several points, so families should view single-year numbers with some caution.

Seneca Junior High is the current academic standout: its 2025–2026 rank is 105 of 643 (84th percentile, 4 stars), and its Forward Exam proficiency is above the state in every reported subject and grade, including 8th grade social studies at 83.33% vs 64.63%. Seneca Elementary is improving—342 of 1039 (67th percentile, 3 stars)—with standout attendance of 5.1% chronic absenteeism, far below the district’s 12.1% and the state’s 17.3%.

Seneca High is mixed: its rank fell to 322 of 533 (40th percentile, 2 stars), and ACT math and science are both 25% vs state rates above 42%, though graduation is 100% and 10th grade social studies is 75% vs 48.25%.

Attendance splits sharply: elementary is 5.1%, while junior high (17.0%) and high school (16.9%) are near the state’s 17.3% and above the district’s 12.1%. Free/reduced lunch is lowest at the high school (34.78%) but highest at the junior high (51.85%), showing demographics alone do not predict results. Spending is similar across schools—about $17,012 per student—while the student-teacher ratio is highest at junior high (15.4). A simple average of reported 2025–2026 tests puts junior high at 80.6% vs state 63.4%, elementary at 73.3% vs 62.6%, and high school at 42.5% vs 45.7%. The district’s middle-of-the-pack ranking masks a strong junior high, a solid elementary with excellent attendance, and a high school with completion and social studies strengths but weaker current ACT and ranking results.
