A Manhattan public school known by the initials “ICE” has undergone an unofficial rebrand this year to avoid any association with Immigration and Customs Enforcement and its controversial actions during the Trump administration.

The Institute for Collaborative Education is now calling itself “Ny.ICE” – an adjustment not taken lightly, the principal said in a Jan. 31 letter to parents explaining the new moniker.

“Moving forward I will be referring to our school community as Ny.ICE or the Institute for Collaborative Education in official communications to avoid any confusion or unnecessary emotional responses to our school’s acronym,” Principal Peter Karp wrote to pupils and parents sent earlier this year and obtained by The Post.

“Although we were founded in 1993, I believe that this is an appropriate and respectful response to the current climate in our city and our country.

“I hope you will join me in this, and know that I do not make this adjustment lightly.”

Students told The Post on Friday they welcomed the rebrand.

“I think that it’s very important that they changed the name because it isn’t a good look for right now because of everything that’s happening politically and just with all the deportations and things like that,” said one 16-year-old.

Another student, 15, said the new name makes her feel better.

“Yeah, a lot better, because I just think it gives, like, a better meaning to the school and it shows, like, it’s more than just what it’s represented like Ny.ICE is just a good diverse… like academics, sports school, they really, like, care about their students and their feelings,” the student, adding, “ICE bad, Ny.ICE good!”

The official name of the Gramercy neighborhood school, which serves 6th through 12th graders, remains the same, a Department of Education spokesperson told Gothamist, which first reported the rebrand.

There are still references to both “ICE” and “Ny.ICE” on the school website and newsletters.

Parents dropping off their kids at the school Friday appeared split on the new acronym.

“I don’t know what else you would expect them to do,” parent David Seiter, 41, told The Post outside the school Friday.

“You know, if you got a name of something….if your school’s name all of a sudden became like a new brand of something that ethically you didn’t support, which it seems like they’ve kind of branded this federal institution with something that a lot of New Yorkers don’t support, then it just seems natural to change it.”

Veronica, 40, said the school name should be left alone, though she understands why the switch was made.

If her 7th grade daughter wears a piece of ICE school apparel outside, Veronica said it could catch New Yorker’s attention.

“And I remember saying, wow, [if] my daughter wears that down the street, you’re  going to have these leftists being pissed off and saying why is she wearing a shirt with ICE,” she said. “So I can understand 50/50 you know.”

“I mean, nobody is really going to care. Nobody wants to be affiliated with ICE, I guess, in this city particularly … But I don’t think really, long term, it’s going to matter too much. People will forget about it,” added 57-year-old parent Patrick Canavan.

There have been fears that immigration authorities would target schools as part of their crackdown on illegal immigration, but a Department of Education spokesperson said students are safe in its care.

“We will always advocate for all of our students, no matter their status,” the spokesperson said.

“As we have said, we urge our families to continue to send their children to our schools, where they are safe.”
