If permitted by policy of the board of trustees, a faculty or staff member, or dependents of the faculty or staff member, may enroll in a class on a space-available basis without payment of tuition. A board of trustees may limit the conditions under which individuals may enroll without payment of tuition or the total number of classes in which they may enroll during a term. An individual who enrolls without payment of tuition because of status as an employee or dependent of an employee is not counted in the computation of full-time equivalent students for purposes of State funding (not applicable to Baltimore City Community College). Instead of a direct tuition waiver, a college may accomplish the purposes of this regulation by tuition deferment or tuition reimbursement if an individual so treated is not included within the computation of full-time equivalent students for purposes of State funding.
