Many students across Long Island were well-equipped to start the academic year, thanks in part to donations of school supplies from residents, businesses and organizations.

One of the biggest efforts came from the Family Service League, which provided more than 3,000 children with new backpacks filled with supplies through its Bethpage Backpack Program. The Huntington-based nonprofit’s action was made possible by donors across the Island, including a $40,000 grant from Bethpage Federal Credit Union.

“When students arrive at school with their backpacks, they’ll have the tools and confidence needed to help them succeed,” said Karen Boorshtein, the league’s president and CEO.

Another large collection was spearheaded by the Long Island Coalition for the Homeless, which gathered more than 1,200 backpacks through its “SOS: Supply Our Students” drive. Donation boxes were hosted by the group’s community partners, such as businesses and libraries.

In addition, 415 children received new clothing along with their backpacks at the coalition’s Backpack Pirates Summer Festival, held in collaboration with the Hauppauge-based nonprofit Holiday Magic.

In the South Huntington school district, about 100 backpacks filled with supplies were given to children in need. Items were provided by the Unitarian Universalist Fellowship of Huntington, Unity Church of Healing Light in Huntington Station and Gathering of Light Interspiritual Fellowship in Melville.

“This amazing gift is truly appreciated,” said Nicholas Ciappetta, president of South Huntington’s school board.
