Signature School Inc

The Signature School Inc district in Evansville, Indiana contains just one school, Signature School Inc, a high school serving grades 9–12 with 384 students. Because the district has only this one campus, district-level and school-level figures are identical across every metric reported here, including a free/reduced lunch rate of 10.68% (roughly 41 students if applied to the full enrollment), a student-teacher ratio of 14.2, and spending per student of $10,641 in 2023–24.

This school is one of the highest-performing in Indiana. It ranked #2 in the state out of 374 districts and schools in the current ranking, placing it in the 99th percentile with 5 stars, and it has held the #2 spot in each of the last three school years (2025–26, 2024–25, and 2023–24) even as the number of ranked schools changed. Test proficiency far exceeds state averages: in 2025–26, 90.11% of students were proficient in SAT Math versus 25.6% statewide, and 95.6% were proficient in SAT Evidence-based Reading and Writing versus 51.9% statewide. In 2024–25, 96.91% were proficient in Biology versus 45.6% statewide.

Trends are mostly positive. Biology rose from 96.91% to 98.99% and SAT Math rose from 84.88% to 90.11%, while SAT ERW dipped slightly from 96.51% to 95.6% — still above 95%, and a smaller decline than the state's. The school reported a 100.0% graduation rate in 2024–25 against Indiana's 89.7%, and chronic absenteeism of 7.9% versus a state rate of 16.7%. The 2025–26 Biology state comparison was not provided, and several measures are shown for only one year, but the available evidence points to a consistently top-tier school.
