New York City public schools will reopen Tuesday for the first time since Hurricane Sandy, after years of work by the city to restore the district.

The district’s first day of classes will be on Tuesday, Jan. 3, 2018, as part of a five-day, 90-day pilot program that will see more than 1,000 students re-learn in the city’s largest public school system, which has long been underperforming and plagued by overcrowding.

It will also mark the first day students in Brooklyn’s schools will be able to participate in the “NYC Schools Week” initiative, a nationwide campaign that aims to raise awareness about school closings by showing students in cities around the world how they can attend school.

As part of the program, more than a million students will be re-evaluated on a weekly basis through a series of visits by school officials.

“It is very important that we give our students the opportunity to have an education they can be proud of,” said Brooklyn District Superintendent Dr. Mark Johnson.

“I hope that we are able to give students and families the best possible experience.”

A total of 1,817 schools have been closed, with another 1,923 slated to reopen.

The districts first day at school was also a chance for the school to be cleaned and refurbished.

In January, the Brooklyn Public Schools opened its first elementary school, the William J. Jackson Elementary School, and a second one later in the year.

Both schools are slated to open on Wednesday, but will be closed for about a month, while the district tries to get its classrooms back to working order.

The district also plans to reopen a second elementary school at the end of the school year, and has plans for another new school to open later in 2019.
