Black students at Boston Latin, the nation’s oldest, most prestigious public school, set off a social media firestorm this week, accusing the elite exam school of ignoring the casual use of racial slurs and offensive online taunts.

In a YouTube video posted Monday, two students representing a group called Black Leaders Advocating for Change and Knowledge said the school has turned a deaf ear to their concerns about classmates’ racial slights.

“We are here to make our voices heard, to show BLS administration and everyone that we refuse to be silenced and we’re not afraid to speak up,” the students say in the video. “We’re here to use this campaign to unite our community, to unite the community of black alumni and the students of color at BLS and schools like it.”

The students encourage their peers to flood social media with accounts of their experiences, using the hashtag #BlackAtBls.

Among the examples the students give in the video: “When people can walk in the halls saying (the n-word) without fear of being reprimanded” and “When your white peers are using Twitter and Facebook to put out racial slurs and negative things about students of color and you print out the tweets and give them to your headmaster in a binder and then she does nothing about it. #BlackAtBls.”

Longtime Boston Latin headmaster Lynne Mooney Teta, who did not respond to a Herald request for comment, acknowledged the students in a tweet Tuesday that read: “Thank you #BLACKatBLS for bringing your concerns forward. Eager to work together to create a better BLS climate for all.”

The brouhaha has forced a meeting tomorrow between the students and school administrators.

Several Latin students wore all black to school Tuesday in solidarity, and the # BlackAtBls hash tag exploded on Twitter this week, with current and past Boston Latin students sharing their own experiences, including:

• “That one time I had to do in house suspension for cutting school because a teacher saw a black girl exiting the bldg #ItWasntMe #blackatbls”

• “When people tell you you’ll get into college only because you’re black. #blackatbls”

• “When your school only acknowledges their students of color when it looks good for the school and their fancy alumni #blackatbls”

• “I don’t know how to describe you, you speak too white to be ghetto #blackatbls”

• “When your teacher calls you the name of three different black girls in the grade ‘cause y’all look exactly alike’ #BlackatBLS”

• “When people look to the 1 black person in the class to represent the black community’s views as they’re discussing black history #BlackAtBLS”

• “When your teacher asks every student who was absent if they had ebola when they get back… #BlackAtBLS”

City Councilor Tito Jackson, who has worked with the students and praised them on Twitter yesterday, said Boston Latin has up to this point “not really taken these what I believe important issues to heart and actually done something about them.”

“It’s my expectation that the school leadership will take the urgent and appropriate steps to ensure the best learning environment for all students at Boston Latin School,” Jackson said.

Rahn Dorsey, Mayor Martin J. Walsh’s chief of education, said on Boston Herald Radio yesterday that officials need to “get to some of the root issues and to talk about substantive practice changes, as well.”

“Whether that’s actual or what those students feel, kind of doesn’t matter,” Dorsey said. “If it’s being raised, we need to address it.”

Boston Latin’s student body is 8.5 percent black — in a district where overall, 35 percent of students are black.

In a statement, Boston Public Schools spokesman Richard Weir said leaders at the school take the students’ concerns “very seriously.”

“The BLS headmaster and assistant headmasters have committed themselves to working together with the students to create a better school climate for all,.” Weir said. “They have invited members of the group to meet with them this week for an important shared dialogue to collaboratively plan a path forward and inform the next steps they will take as a school community.”

Boston NAACP President Michael Curry said the concerns date back to comments some students endorsed on social media in the aftermath of the 2014 Ferguson, Mo., police shooting, including one that stated blacks “should just go back to Africa where they belong.”

“It made them feel very uncomfortable, because these are kids who were sitting in the class with them, and they had to work on projects with,” said Curry, who’s met with students at Latin over the issue. “If you don’t do something about it, it can boil over, and we don’t need that is in our school system, especially at one of the premiere schools in the country.”
