The study found a strong correlation between kindergarten test scores and key life outcomes such as income at age 27, college acceptance rates, and retirement savings. While the direct impact of class size on income is not statistically precise, smaller class sizes significantly improved college attendance. Furthermore, students randomly assigned to highly qualified teachers or high-quality classes (measured by peer performance) experienced higher economic returns in adulthood. Although the academic advantage of quality education gradually diminishes in the later grades of elementary school, its shaping of non-cognitive abilities (such as responsibility and initiative) is enduring and ultimately translates into a competitive advantage in adulthood. Therefore, improving the quality of early childhood education has significant and far-reaching economic value in enhancing individuals' long-term quality of life.
