High school graduation rates have soared across the country over the last decade, accompanied by the cheers of educators and lawmakers alike. But in the vast majority of states, simply attaining a high school diploma does not qualify students to attend a public university, according to a study released Monday by the Center for American Progress.

The report examines coursework requirements in math, English, science, social studies, foreign languages, art, physical education, and electives for both graduation from a public high school and entrance to a public university in every state, Puerto Rico, and the District of Columbia.

“Within a state, it should be clear — and it should be aligned — that if I go to a public high school system, I should be eligible for a public university system in my state,” study co-author Laura Jimenez, the director of standards and accountability at the Center for American Progress, told The 74.

In just four states — Louisiana, Michigan, South Dakota, and Tennessee — do the requirements to achieve a basic diploma (i.e., non-honors) also qualify a student for enrollment at a public college. Alaska, Puerto Rico, and Washington, D.C., are also technically aligned, but only because their respective public college systems don’t make any coursework requirements.
