 1/2 of the Kindergarten class begins the day, 1/2 on Thursday Sept 3. 

The first day of school for grades 1-5 is Wednesday, September 2nd.  Kindergarten first days begin with half class. This allows for a more gradual adjustment and additional support for each incoming student. Students with last names beginning with A-L will attend Kindergarten on Wednesday, September 2nd (and will not attend on September 3rd.) Students with last names beginning with M-Z will attend on Thursday, September 3rd (and will not attend on September 2nd).
