Credit by Demonstrated Mastery

Credit by Demonstrated Mastery or CDM is the process by which Johnston County Schools shall, based upon a body-of-evidence, award a student credit in a particular high school course without requiring the student to complete classroom instruction for a certain amount of seat time. “Mastery” is defined as a student’s command of course material at a level that demonstrates a deep understanding of the content standards and application of knowledge.

The intent of the CDM process is to provide subject acceleration for students who have already mastered the content standards for a particular course.  However, it is important to keep in mind how obtaining credit will impact the student’s course of study for the remainder of high school. Since CDM only awards general level credit and it not factored into GPA’s, students will want to work with counselors to select additional advanced level courses (AP, IB, or CCP) to fit their needs if CDM credit is awarded.  


Students may apply for CDM for a course by following these steps:

  • Complete a CDM Application in full and return by the determined deadline (available from school counselor).
  • Agree as part of the application that the any student who passes the Phase 1 assessment, commits to fulfill all Phase 2 artifact requirements.
  • Meet with a school counselor to ensure understanding of the process and implications of further coursework if a student is successful at CDM.
