Mayor Bill de Blasio says John F. Kennedy High School in Manhattan will open on-time with the rest of the city's public schools.
The announcement comes just weeks after part of the school was leveled by a gas explosion.
Speaking exclusively with NY1, Mayor Bill de Blasio says students will be welcomed back for the first day of classes on September 9.
Parts of the school will be sectioned off because of the damage caused by the blast.
Mayor de Blasio commended the hard work of everyone involved in restoring the school to a condition that would make it safe for all three-thousand students to return.
"There was very extensive damage from the accident that occured. The amazing thing here is the buildings department, the health department, the school construction authority, they all swung into action. They've literally been working seven days a week, many instances around the clock. And the good news is that all of that hard work has paid off," the mayor said.
On August 20, three classrooms in the school were destroyed when fire officials say workers lit a match right before testing a newly installed gas line, causing the explosion.
The mayor says the three workers who were burned in the accident are still recovering from their injuries.
