Who knows better the peer pressures that students in a school face than those students themselves?

When an anti-bullying presentation conducted by an adult from outside their school fell flat, Bryan Stromer, then a senior at the NYC Lab School for Collaborative Studies in Chelsea, thought to himself that the students could do it better.

“Students are the ones in school every day; we know what the issues are, so we can be the biggest problem solvers,” Stromer said.

He had been a founding member of the Stand Up to Bullying club at his small school, but in 2012, he had a brainstorm: What if they could get students to embrace their differences — the very things that may have been the cause of teasing throughout their lives?

Stromer, who has cerebral palsy, had always felt somewhat different and accepted that difference: “I’ve always owned my walk,” he said.

With support from his fellow students as well as guidance counselor Jennifer Schatz and Tim Shriver from the nonprofit Future Project, Own It was born. Posters began popping up all over the school, with questions like “What’s your wildest dream?” or “What’s your most awkward trait?”

Students and faculty wrote their answers on a chalkboard set up in the hallway and on cards. Students next brought the campaign online, with popular Tumblr and Instagram sites. To view the responses of students and educators to a host of intriguing and unusual questions, visit www.ownitnyc.org.

The site also has a tool kit, where students can download graphic elements and bring the program to their own schools, which has already begun to happen. By the school year’s end, Stromer said that 75 percent of the Lab School’s student body participated in the campaign and another 24 schools had signed on.

UFT Safety Director David Kazansky met Stromer when he came to the union’s first anti-bullying fair two years ago.

“This is exactly the kind of thing that the union’s BRAVE campaign hopes to have happen in every school — we want to inspire students and teachers to become architects of anti-bullying solutions in their own schools,” Kazansky said.

Lab School senior Gina Fuchs and a crop of other junior and senior students are taking Own It in a new direction this school year. While last school year’s culminating event was a hugely successful assembly attended by the chancellor, this year’s focus is on bringing the program to the incoming freshman students.

“As a senior, I’m an advisor to 12 freshmen, and we want to make part of the advisory about owning it, expressing yourself and not being afraid to be different,” Fuchs said.

“Students have a much wider awareness of bullying and where it happens ... and with the support of teachers, Own It has been allowed to thrive in our school,” she said.

Guidance counselor Schatz, who supported the program’s first-year assembly and met with students to help plan it, said, “The idea caught on because teens struggle with acceptance in high school and they hide parts of themselves that are not cool or mainstream.” The Lab School, she said, is a school that actively promotes tolerance and acceptance, with many student-led clubs and organizations.

“If you put your biggest insecurities out there, you’re disempowering people who would want to hurt you with them,” said Schatz.
