Grace Trinidad, 34, a dean of discipline at New Visions Advanced Math & Science High School, befriended the teen and repeatedly invited him to her home in the South Bronx, according to cops.
Police say the 15-year-old victim engaged in intercourse with Trinidad on Aug. 31 inside  her home in the Bronx, NY.
During their most recent encounter, Trinidad and the student were watching movies when they began kissing and performed sex acts on each other, authorities allege.
The alleged incident was subsequently reported to authorities Monday.
Trinidad is facing charges of rape, engaging in a criminal sex act and unlawful dealing with a child. Detectives from the 40th Precinct were alerted to the abuse after the student and a classmate told the principal what happened, sources said. Trinidad was arrested at her home after questioning Tuesday. She was charged with rape in the third degree for having sex with a minor, criminal sex act and endangering the welfare of a child.

Trinidad’s neighbors said she shares her apartment with two daughters, who one neighbor estimated are fourth- and sixth-graders. Jose Gustavo, 25, said he knew Trinidad from growing up in the neighborhood and called her “a wonderful human being.” “She’s good people,” he said. “I don’t know what happened here.” Gustavo said Trinidad took over the apartment from her mother after she died. Students outside the charter school Tuesday afternoon said they’d heard about the allegations but were uncomfortable talking about them.
“It was unexpected,” said one teenage boy. “It’s just messed up that it even happened. There’s a line between school and outside, and personal life — and she crossed it.”
New Visions is one of several high schools located in the old John F. Kennedy High School building in Spuyten Duyvil.
The school opened in 2011 and enrolls almost 500 students. Trinidad’s Facebook account lists her starting a job as dean at the John F. Kennedy building in 2017.
New Visions for Public Schools operates eight charter schools in the city.
Trinidad is listed on the charter school’s website as a dean coordinator for discipline.
