A dad has started a petition for his son's teacher to be sacked after seeing the comment she wrote on his maths homework.
Chris Piland was shocked when he saw the feedback on Kamdyn's test criticising his efforts.
The eigh year old children, were tasked with solving as many subtraction problems in three minutes from a list of 60 as they could.
The teacher wrote: "Absolutely pathetic he answered 13 in 3 min! Sad" with a drawing of a sad face.
Chris, who lives in Pennsylvania, was so outraged by the comment he decided to set up a petition calling for her to be fired, which now has more than 15,000 signatures.
Sharing a photo of the homework, he wrote: "My son Kamdyn's teacher has been so rude to him and myself all year.
"He comes home with this and I am beyond frustrated that someone would write this on a child's work. Such great motivation."
Chris has since posted an update to say the school board is investigating.
He wrote: "Thanks to all the efforts and support of the dedicated people who signed and shared this petition, I'm happy to announce that the teacher in question is currently being investigated by the Valley View school board."
Many people have been shocked by the teacher's message.
Commenting on the petition, one woman wrote: "I don’t even have a child and this is sickening to me. This is so beyond unprofessional and just wrong."
Another added: "No teacher has the right to write such awful comments on a young child's work."
School superintendent Rose Minniti said: "It's a personnel issue and the results of that are not going to be dictated by social media", reports Mail Online.
"It's going to be dictated by the facts and evidence.
"As always with everything, we're going to try to do what's best for the students and what we need to do for the employee under investigation."
