The Promotion rate reflects the percentage of students promoted during the school year. Students that advanced from one grade to a higher level are defined as promoted. Students receiving a Maryland High School Diploma and Certificate of Completion along with grades pre-kindergarten through grade 12 are included. The Promotion rate percentage is calculated by dividing the aggregate number of students promoted by the aggregate number of students enrolled as of the end of the school year. Summer promotions are included in the promotion rate percentage.
