Credit by Demonstrated Mastery (CDM) provides the opportunity for students in Durham to personalize and accelerate their learning by earning course credit through a demonstration of course material mastery without the requirement of a specific seat ­time. Students are required to complete a two-phase process in order to demonstrate command of the course material at a level that demonstrates a deep understanding of the content standards and the ability to apply his or her knowledge of the material.

The process for CDM includes an online application, Phase I assessment, and Phase II artifact and/or performance assessment. Students will be required to demonstrate mastery at a superior level, 90% or greater, at both phases. 

Access to the CDM process is open to all NC public school students for courses in grades 9-­12 and high school courses offered in grades 6-8, except for the following:

  • English Language Learner (ELL) courses

  • Healthful Living required courses

  • AP/IB courses, CTE courses that are work-based (coop, internship, apprenticeship); require a clinical setting (ProStart, Early Childhood Education I/II, and Nursing Fundamentals); and/or Advanced Studies
