A Texas middle school teacher was terminated for assigning an illustrated adaptation of Anne Frank’s diary to her eighth-grade class,

The Hamshire-Fannett independent school district fired the teacher after deeming the book “inappropriate” and unapproved for use in the curriculum.

The graphic novel, created by Ari Folman and illustrated by David Polonsky, retells Anne Frank’s story during her time in Nazi-occupied Amsterdam, including passages discussing sexuality. While the district initially stopped students from reading the book and issued an apology to parents, they later confirmed the teacher’s dismissal, refraining from disclosing specific details about the incident.

The graphic novel version of Anne Frank’s diary has been the subject of bans before. There are passages that allude to sex in the original diary as well but they are often redacted in reprints.

This incident is occurring amid a broader context of educational laws restricting the teaching of topics related to race, sexuality, and other sensitive subjects in classrooms across the United States.
