K–16 is a movement in the United States to bring together the various levels of education for younger students, namely between the K–12 and the post-secondary education systems, and create aligned policy and practice in examination practices, graduation requirements, admissions policies and other areas.
Community colleges with associate degrees are equal to grades 13 to 14.
Universities offer grades 14 to 16 with a bachelor's degree.
Master university degrees would then be grades 17 to 18.
Doctorate degrees offer 19-21st grade.
