The Microschool Movement: Why Small Is Becoming Education's Next Big Idea
Between 750,000 and 2.1 million US students now attend microschools — small, mixed-age learning environments that reject the 30-student classroom in favor of ratios as low as 3:1. University of Chicago research shows high-dosage small-group instruction can double or triple learning in a year. But RAND found measuring microschool outcomes is "nearly impossible." As public ESA funding flows in, the equity and accountability questions can no longer wait.
