Westmont’s Holy Trinity Catholic School – a Thriving Catholic Microschool
Microschooling is an approach for institutions with fewer than 150 students; it involves teaching students in multi-age classrooms, where teachers focus on teaching to individual students, rather than the class. Across the country, microschool administrators and teachers report students performing above average on standardized tests, attributing success to small class sizes and the mutli-grade model. Holy Trinity School in Westmont, Illinois, a suburb of Chicago, adjusted to the microschool model two years ago. A 2024 standardized test for K-8 students indicated that 45% of students were at or above grade level in reading and 39% in math. But by spring 2025, scores increased to 82% in reading and 79% in math.
