The Carrollton-Farmers Branch Independent School District placed three teachers on administrative leave after they included “derogatory” language about Asians on a social studies test, the district said in a statement Wednesday.

The secondary social studies test asked students to identify which of three statements about “Chinese norms” was true, according to a report by WFAA, which reported the test was given to students at Blalack Middle School. The statements presented racist stereotypes about Chinese people.

“Recently, we learned of a situation where three teachers used inappropriate language about Asian Americans on a secondary social studies test,” the school district said in a statement released Wednesday. “The words used on the test question were derogatory and hurtful.”
