AMES, Iowa (AP) — A central Iowa school principal suspended after concerns were raised about student-to-student bullying has resigned. Ames Community School District says Dan Fox will not return to his duties at Ames Middle School and will leave district employment effective June 30. Fox was suspended in late November. Concerns were raised by parents and students, and an online petition appeared that sought improved safety for LGBTQ students at the school. District officials have said the decision to suspend Fox wasn’t based off just one incident but rather was an effort to improve the school. He’d been hired in June last year.
