Summary:
Fort Branch, Indiana is served by two public schools — one high school and one K–8 elementary — both part of the South Gibson School Corporation, with no separate middle or alternative schools in this list. Together they enroll about 1,319 students, and the district itself ranks 39th of 374 Indiana districts, in the 90th percentile.
Gibson Southern High School (grades 9–12, 742 students) is the standout: its 2025–2026 rank is 39th of 415 Indiana high schools, the 91st percentile with 5 stars, up from 4 stars in the two prior years. It graduates 95.9% of students versus 89.7% statewide, has 5.4% chronic absenteeism versus 16.7% statewide, and scores 70.56% in SAT Evidence-based Reading and Writing and 45% in SAT Math, against state marks of 51.9% and 25.6%. Its SAT math result climbed 13.48 points in a year. Fort Branch Community School (grades K–8, 577 students) ranks 226th of 1,015, the 78th percentile with 4 stars, and beats the state in every reported 2025–2026 grade-level test, including 8th Grade Math at 55.84% versus 34.2% statewide.
Parents should note the two schools differ in context: the elementary school spends more per student ($10,803 vs. $9,806), has smaller classes (16.8 vs. 18.3 students per teacher), and serves more low-income students (32.76% vs. 23.72% free/reduced lunch). Its chronic absenteeism is 7.9% — low, but above the high school and district. Its all-grades math (56.28%) trails the district (59.73%), while ELA improved year over year. Overall, both schools outperform the state, with the high school among Indiana's top decile.
