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.

Online Learning Program

In accordance with the Governor’s guidelines and the AIMS recommendation, Holy Trinity has temporarily suspended on-site learning until April 24th. All Holy Trinity students from preschool to grade 8 will be engaged in an Online Learning Program (a combination of distance and virtual learning). Our faculty is offering innovative instruction as we encourage our students to be “The Best You”.  Students should check the Portal regularly. 

The Admissions Office is operating on a normal schedule during this period. Although our April Open House is cancelled, we invite prospective families to reach out to our Admissions Director, Rosalyn Cruz.
