Please check the information in Sapphire and Blackboard Connect at www.slsd.org. Update all phone numbers, email addresses and addresses. Also, check contact information to ensure we have the names and numbers of individuals who can be responsible for your child in case of illness, injury or other urgent situations should we be unable to reach you. These contacts are only used when we are unable to reach you directly. If you have moved, you will need to provide proof of residency to our Central Office at 5775 Main St. Center Valley, PA 18034, or your child's school.
