The last day of school depends on how many snow days we have. When the 2011-2012 school year calendar was originally set, Monday June 18 was identified as the "Earliest Last Day of School." However, we already have had five snow days due to the October storm. If we have any more snow days (perish the thought!), then that day will change again. The monthly calendar on the ARHS website is updated for each snow day and shows the correct dates for exams in June. At present, the last day of school for Regional students is posted as Monday June 25th (includes 5 make-up days) Please note: The last three days of school are half-days at HS due to exams.
