A high school teacher in Jacksonville, Florida, who allegedly wrote a message on a classroom board reprimanding students who don't stand for the Pledge of Allegiance has been removed from the classroom.

Duval County Public Schools said it learned of the teacher's statement Wednesday afternoon.

"The message included historical references including slavery, the right for women to vote and the election of a black president. It also referenced the fact that the superintendent of the school district is black. It was implied in the statement that students who fail to stand for the Pledge of Allegiance lack maturity," DCPS said in a news release.

The statements made by the teacher are not consistent with state statute or school board policy, DCPS said:

The school has referred the matter to the district's Office of Professional Standards for review.
