As Winter Storm Stella prepared to blanket the Northeast with more than a foot of snow this week, education officials were getting ready, too, by canceling school. Districts and schools in New York, New Jersey and other states called off classes Tuesday in advance of the impending blizzard.

New York City's public school system was one of the first to announce it was shutting down for the snow. In addition to all schools closing, after-school programs, adult education programs and other extracurricular activities were canceled, according to the city's education department.
