Idea Tres Lagos College Preparatory is a school of notable contrasts. It is part of the Idea Public Schools district, which ranks in the 43rd percentile statewide. The school itself shows a positive trajectory, improving its state ranking from the 44th percentile in 2023-2024 to the 52nd percentile in 2025-2026, earning a 3-star rating. Academically, the school excels in Biology and U.S. History, with 75.57% and 76.32% of students proficient respectively, both exceeding state averages. However, it struggles in core subjects like English I Reading (42.35% proficient) and Algebra I (47.48% proficient), which are critical for graduation. The school also serves a predominantly low-income student population, with 80.58% qualifying for free or reduced lunch, and has a student-teacher ratio of 16.4.
A key takeaway is the school's "middle school advantage," as its 6th, 7th, and 8th grade reading scores all surpass state averages, while its high school End-of-Course exams fall below. This suggests stronger preparation in earlier grades. Additionally, U.S. History scores saw a dramatic 23-point swing from the previous year, warranting further investigation. Despite socioeconomic challenges, the school's consistent upward ranking trend is a positive sign of improvement efforts. Overall, Idea Tres Lagos College Preparatory is a school with clear strengths in science and history, but with significant room for growth in math and English at the high school level.
