The VEIP testing locations are closed on holidays.  There are also days each year in addition to holidays that the testing centers will be closed in order to help reduce the state’s budget.  It is recommended you call ahead of time to ensure the testing center you plan on attending is open on the day you plan to attend.  The number to call is 1-800-638-8347.
