A Brooklyn teacher will pay a $1,500 fine for asking the mother of a 4-year-old student to loan her a food stamp card, officials say.

The teacher, who worked at P.S. 308 in Brooklyn, admitted to asking the mother if she could use $100 on the SNAP card because she had spent too much money on her newborn grandson, according to the Department of Education's Conflicts of Interest Board.

She put a note in the student's backpack addressed to the student's mother, the board said. In the note, the teacher explained why she wanted to use the card, said she needed "about $100 or less" and offered to pay the mother back in cash.

The mother did not respond to the note or give the teacher the card.

The teacher agreed to pay $1,500 fine to the Conflicts of Interest Board and to be placed on the DOE's Absent Teacher Reserve, according to the COIB disposition.

NYC's conflicts of interest law prohibits public servants from using or attempting to use their city positions to obtain personal benefit.
