All divisions of Greenhill School will begin the 2020-2021 school year with remote classes rather than in-person instruction as a result of the Covid-19 pandemic, Head of School Lee Hark announced Friday in an email sent to parents.

Academics, athletics and arts will be held online starting Tuesday, Aug. 25, the email said.

The announcement came after Dallas County Health and Human Service said Thursday that all schools in Dallas County will not be permitted to hold classes or activities in person until after the Labor Day holiday on Sept. 7. Whether classes at Greenhill or other schools will be allowed to resume in-person classes after that date will hinge on the success of ongoing efforts to contain the pandemic.

“We will share a definitive date for returning to campus for in-person instruction as soon as we are able,” Hark said.

Greenhill shifted to remote classes amid the worsening pandemic last March. In the face of the continued uncertainty, faculty members have engaged in online-education training over the summer, Hark said.

“We have worked hard this summer to prepare a robust, retooled system of remote instruction,” Hark told parents in the email.

Additionally, fall athletics have been delayed until at least Sept. 8. The Southwest Preparatory Conference (SPC) Board of Directors recently announced that competition will begin on Sept. 22 at the earliest.

Hark expressed confidence that the Greenhill community will remain strong and connected, regardless of the mode of instruction.

“Our partnership—#GreenhillTogether—will continue to help us build relationships, advance our academic mission, and ultimately emerge a stronger school,” Hark said.
