College prep is generally a different program than HS (However I did attend a college prep high school so it was a combined effort but I transferred so I never graduated with a college prep diploma) high school is general education while college prep is literally preparation for college, so no? I think a diploma should remain a diploma, and college preparatory should remain college prep. You get a different diploma from graduating from a college preparatory program that is ultimately better for college bound students than a general diploma
