    Dear Orange Township, Public School District Staff, Families, and Caregivers,

    As we are still immersed in a pandemic, our stellar staff continue to work closely with students. In addition, teachers continue to work alongside their colleagues to ensure that the instructional scenarios presented to students are differentiated, targeted, and intentional. Through professional development opportunities and collaboration, teachers are prepared to educate our students in any scenario. with this in mind, to ensure a smooth transition back to in-person instruction following the holiday break, students and staff will return as per the following schedule: Students will return on January 18, 2022, for in-person instruction after the Martin Luther King Jr. Observance Day (though synchronous instruction will commence daily from January 3, 2022, through January 14, 2022.) Synchronous daily learning beginning January 3, 2022, will follow the student’s full schedule. The school day will be the full length of the instructional day.
