Summary
Lake Central High School is a large public high school serving grades 9–12 in Saint John, Indiana, enrolling 2,926 students as part of the Lake Central School Corporation, a district ranked 27th of 374 in Indiana. The school is a consistently strong performer statewide: it ranked 33 of 415 Indiana high schools in 2025–2026 (92nd percentile, 5 stars), 22 of 429 in 2024–2025 (95th percentile, 5 stars), 29 of 432 in 2023–2024 (93rd percentile, 5 stars), and 25 of 398 in 2022–2023 (94th percentile, 5 stars) — a steady 5-star run after moving up from 4 stars in the mid-2010s.
Academically, Lake Central posted 46.27% proficient in SAT Math in 2025–2026, nearly double the statewide 25.6% and ahead of Crown Point High School, Hanover Central High School, Highland High School, Merrillville High School, Morton Senior High School, and Calumet New Technical High School; only Munster High School was slightly higher. Reading (66%) and biology (60.7%) scores also sit well above state averages, and the graduation rate reached 96.1% in 2024–2025 versus 89.7% statewide. The school also ranks among Indiana's top 10% for many student groups, including a 2024–2025 ranking of 1st of 119 for English Language Learner students.
The clearest concern is chronic absenteeism: 24.3%, above the district's 16.2% and the state's 16.7%, and higher than Crown Point, Highland, Hanover Central, and Munster, though lower than Merrillville, Morton, Calumet, and the Excel Center - Hammond and Excel Center - Gary. At the same time, the school spends $10,837 per pupil — lower than every nearby traditional comprehensive high school — with a 20.2 student–teacher ratio, tied with Crown Point for the highest in the comparison group. That mix points to efficient results, with attendance the clearest opportunity for improvement.
