Students are asked not to arrive before 7:15 a.m., as adult supervision is not available before that time.  A warning bell will ring at 7:35 a.m. All students are expected to be in class by the 7:45 a.m. bell.  Supervision of students occurs: When students are on the school bus, attending school, or are participating (with authorization) in a school-sponsored activity.  Supervision also occurs 30 minutes before and after student required attendance at school or before and after the beginning and ending times of a school sponsored activity in which students are authorized to participate.  There is no school board supervision of students except during these times.
