Summary
Indiana Gateway Alternative School is a public alternative high school in Clarksville, Indiana, serving grades 9–12 with roughly 365 students as part of the Clarksville Community School Corp, located in the Louisville-area suburbs just north of the Ohio River.
The school sits at the very bottom of Indiana’s high school rankings: 411th of 415 in 2025–26 (1st percentile, 0 stars), after ranking in the 8th percentile in 2023–24 and the 6th percentile in 2024–25. Its graduation rate was 53.3% in 2024–25, down from 58.4%, which is roughly 36 percentage points below the state and about 15 points below its own district. Chronic absenteeism was 66.8% — more than double the district rate of 32.1% and about four times the state rate of 16.7%. Test proficiency is very low: SAT ERW was 8.86% and SAT Math 0% in 2025–26. The contrast with its same-district peer, Clarksville Senior High School, is striking — that school is 0.27 miles away with similar enrollment and a nearly identical free/reduced lunch rate, yet posts a 95.5% graduation rate, 27.4% chronic absenteeism, and 48.48% SAT ERW. Compared with another nearby alternative-style school, Excel Center - Clarksville, Gateway has a higher graduation rate (53.3% vs. 29.1%) and much lower absenteeism (66.8% vs. 96.9%).
Gateway spent $7,817 per student in 2023–24, less than nearby traditional high schools such as Clarksville Senior High ($11,180), and its student-teacher ratio rose to 17.8 in 2024–25 from 14.4 the year before. Its free/reduced lunch rate of 47.12% is similar to Clarksville Senior High’s 46.36%, so poverty alone does not explain the gap. Performance is low across nearly every student group tracked — female and male students, students from low-income families, and students in special education all rank in the bottom 1–10% statewide, suggesting a schoolwide challenge rather than isolated ones. As an alternative school, Gateway likely serves students who are off-track or credit-deficient, which explains some differences from comprehensive high schools like Floyd Central High School (97th percentile). Even so, attendance, credit recovery, graduation pathways, and core math and reading intervention stand out as the most urgent needs.
