A former Harlem charter school teacher was sentenced Monday to 1-1/3 to four years in prison for sending sexually explicit videos to a student.

Jeffery Bryant, 26, copped to disseminating indecent material to a minor in August as part of a plea deal that covered the entire indictment, including allegations he asked a student for a threesome, sent two other girls sex videos and sexted a fourth child.

Prosecutor Melanie Soberal said that Bryant had abused his position of authority by sending the pornographic material. She added that he had also encouraged his students to smoke marijuana and drink alcohol.

One of his victims was in court but chose not to deliver a statement.

“She is here because of the impact that this case has had on her,” Soberal said before Manhattan Supreme Court Justice Curtis Farber handed down the promised sentence.

The ex-middle school history and music teacher at Democracy Prep Endurance was busted in March after a student reported Bryant’s sick behavior.

The teacher had only been at the school for three months when he started sending the raunchy videos and texts to eighth-grade students, including two 13-year-olds and a pair of 14-year-olds, according to court records.

He sent a video of himself having sex with a woman to one victim and a clip of himself nude to another, states a criminal complaint.

School officials told The Post that after the student reported him, Bryant was axed and the cops were called.

Bryant, who is married and has a 1-year-old daughter, claims to have a bachelor of arts degree in biblical studies from the Christian Bible Institute, according to his Facebook page.

His lawyer, Melanie Dearth, declined to comment.
