1. The EOC assessment is a mandatory component of the course, governed by State Board of Education policy TEST-003.

• Mandatory Enrollment: All public school students enrolled for credit in an EOC course (such as English II) must take the appropriate EOC test at the completion of the course.

• No Exemption: Students who are exempt from local board final exams are not exempt from the EOC test.

• Course Status Irrelevant: Students must take the EOC regardless of the grade level in which the course is offered, and even if they are identified as failing the course.

• First Time Requirement: Students are required to take the EOC the first time they take the course.

2. The EOC assessment must be taken at the completion of the course during a designated testing window.

• 10/20 Day Drop Rule: Students enrolled for credit may drop an EOC course only within a specific timeframe:

  • The first 10 days of enrollment in a semester block schedule.

  • The first 20 days of enrollment in a yearlong traditional schedule.

• Students enrolled after the 10/20 day window shall not drop the course and must participate in the EOC assessment.

3. The test format and score use are fixed by state policy.

• All EOC assessments are required to be administered online through the NCTest system.

  • Exceptions are made for students with documented disabilities requiring a paper/pencil format.

• The EOC assessment result must be used as a minimum of twenty percent (20%) of the student's final course grade for each respective course.
