In the event of inclement weather or poor road conditions, classes may be cancelled for the safety of our students and faculty. When Centerville City Schools are closed due to the weather, SDSD will also be closed. Please check your email for a notification of closure, or call the school to hear a current message as to class status. Students may obtain a make-up class pass for classes cancelled due to weather, which must be used within two (2) weeks of missed class date. SDSD does not credit, refund, or pro-rate tuition for classes cancelled due to poor weather.
