Parents must be kept informed about their student’s grades, overall performance, and absences. Therefore, report cards will be sent or made available electronically to parents at intervals corresponding with the grading period length used at any given school, typically ranging from six-week to nine-week intervals. Parents are requested to schedule a conference with their student’s teacher if he or she is not making adequate progress. Grades issued by a classroom teacher are final and may not be changed unless the grade is arbitrary, erroneous, or not consistent with the school policy applicable to the grade, as determined by the Board of Trustees.
