Governor Phil Murphy made the announcement last month, citing the rapid easing of the omicron surge.
He called the move "a huge step back to normalcy for our kids."
The mandate has been in place since classes resumed in person in September 2020.
"We are not, and I've said this many times, going to manage COVID to zero," Murphy said. "We have to learn how to live with COVID as we move from a pandemic to an endemic phase of this virus."

Though the state mandate has ended, individual school districts are free to continue requiring masks.
Several school districts in the state are still making masks mandatory, including Paterson, Newark, and Trenton.
But for districts making face masks optional, most kids and parents were happy to see their smiling faces again.
The city of Hoboken also announced Monday that its COVID-19 State of Emergency has been lifted following a decline of confirmed positive COVID-19 cases across the city and the region.
"After two long, hard years, we are finally at a time where it is no longer necessary to remain under a State of Emergency," Mayor Ravi Bhalla said. "This is a credit to everyone who has chosen to get vaccinated and boosted, which has helped get us through the hard times of the past year. We will continue to be guided by science as the pandemic becomes an endemic, utilizing the tools we know will protect our residents."
Hoboken's Office of Emergency Management first declared a State of Emergency on March 12, 2020.
