A high school teacher in Springfield, Florida is facing backlash after she wrote, "Wtf is this" on her student's homework assignment. The unnamed educator, who teaches science at Rutherford high school, added, "Absolutely no credit" underneath the acronym.

The teacher's feedback angered the student's mother, Melinda Smith, who says she was appalled when her son brought home his assignment and saw a NSFW expression written at the top of the page. “It wasn't anything about not getting the credit, it was more so the language...That was very inappropriate and not acceptable for a teacher whatsoever," she told local news station WJHG.  

Smith added that she hopes the teacher will be punished as a result. "I think for sure she needs to be reprimanded. I believe that something should be placed in her file," she said. 

School officials, who have refused to release the teacher's name, have confirmed that they are investigating the matter and are taking steps to discipline the woman. “Our HR has been involved and they’re currently investigating the situation,” principle Coy Pilson said.

“She was apologetic and it was a mistake on her part,” Pilson said. “All of the teachers at Rutherford High School are caring, loving teachers and we’re also human and so, we make mistakes, but we understand that we are called to a high professional standard and when we make mistakes, we try to correct those mistakes and move forward.”
