Credit by Demonstrated Mastery (CDM)

  • Students may earn high school credit for specified courses without spending a set number of hours taking the course in a classroom. Under the state’s Credit by Demonstrated Mastery (CDM) option, uniquely qualified students may “test out” or bypass a course if they have already mastered the content. The program provides another opportunity for students to learn new content, to challenge themselves with the next level of rigor in a subject, and even graduate early. This option is not designed to replace existing accelerated pathways, such as the Academically and Intellectually Gifted (AIG) program at WCPSS.

    The application window for Credit by Demonstrated Mastery for the 2020-21 school year has now closed. Students who are interested in pursuing CDM in the 2021-22 school year may check back for additional information next school year. Questions can also be directed to Mr. Carrington at
