Research by Achieve, ACT, and others suggests that for high school graduates to be prepared for success in a wide range of postsecondary settings, they need to take four years of challenging mathematics--covering Advanced Algebra; Geometry; and data, probability, and statistics content--and four years of rigorous English aligned with college- and career-ready standards (which include the CCSS). While readiness depends on more than knowledge and skills in English and math, these core disciplines undergird other academic and technical courses and are considered essential by employers and colleges alike. For students to truly graduate ready for college and careers, however, they need to complete a rigorous, robust and well-rounded curriculum that exposes them to a wide range of academic and technical knowledge and skills to ensure all doors are left open for them when they leave high school. Today, 19 states--Alabama, Arizona, Arkansas, Delaware, Georgia, Hawaii, Indiana, Kentucky, Michigan, Minnesota, Mississippi, Nebraska, New Mexico, North Carolina, Ohio, Oklahoma, South Dakota, Tennessee and Utah--and the District of Columbia, have elevated their high school diploma requirements to the college- and career-ready level. This paper offers a comparison table of graduation requirements in these 19 states.
