Extended Day Program

Holy Trinity’s Extended Day Program has been designed as a service to parents and as a benefit to students. Students are placed in age-appropriate groups, provided with a snack, given an opportunity to play outdoors, begin homework, and offered a variety of indoor activities. Extended Day is available only on regularly scheduled school days. There is no Extended Day on the afternoons prior to Thanksgiving, Christmas and Easter, during vacation periods, or other “No Class” days. When school opens one or two hours late, Extended Day will be similarly delayed. There will be no after-school Extended Day when school closes early due to inclement weather.
