Previous research has linked higher levels of academic preparation as measured by the ACT® to postsecondary success, such as earning higher college grades and completing a college degree in a timely manner. This ACT Data Byte extends these findings, illustrating the positive relationship between graduating from high school college and career ready and future annual earnings. Data from a collaboration between ACT and Opportunity Insights--a non-profit organization located at Harvard University--show that the annual earnings individuals' report during their late 20s are positively related to their academic achievement level measured during high school.
