Parents are requested to email attendance and/or call the Health Office at (202) 337-2339 ext. 213 before 8:10 AM and leave a detailed message if their child will be absent on a particular day. As a safety measure, we alert parents if their child is not in school. Please make sure the office has current phone numbers for both parents. Please contact the main office (or email updates@htsdc.org) with any contact changes so our school records may be adjusted immediately should your contact information change.
