Diane Tirado

Diane Tirado is a former Florida teacher who gained media attention after being fired in 2018 for refusing to abide by her school's 'no-zero' grading policy, which mandated that students receive a minimum grade of 50% regardless of whether they submitted assignments. Tirado, who had 17 years of teaching experience, argued that grading should reflect students' actual performance. Following her termination, she faced professional repercussions and filed a federal lawsuit claiming retaliation for her stance against the policy, ultimately losing her case and stepping away from the classroom.
