A former Metro Nashville Public Schools Teacher of the Year says district practices, including being asked to change a student's failing grade, drove her out of the classroom after nearly a decade. The district disputes key parts of her account.
Samira Hardcastle, who graduated from Metro Schools and taught math and art for eight years, resigned in May and read her resignation aloud at a board meeting on Tuesday. She said she had been named Teacher of the Year at John F. Kennedy Middle School in Antioch and the district's Blue Ribbon Teacher of the Year. Her post about leaving spread widely on social media.
Hardcastle said working with kids was the best part of the job and the thing she will miss, but that parents, student behavior, politics, and regulations piled up until, as she put it, she "really wasn't even teaching anymore."
Her central claim concerns grades. Hardcastle said district leaders asked her to "fabricate grades" for a parent who sat in a school office for hours until a daughter's failing marks were changed. When a complaint reaches the district, she said, administrators tend to side with the parent to end the dispute.
Metro Nashville Public Schools rejected that framing. Her account "does not fully reflect what occurred," the district said, based on the principal's account and what it could review. By the district's telling, a parent raised a concern in October about an art-class assignment, and the principal and an executive director reviewed it. One question was whether the student should be allowed to finish an assignment that had not been turned in. The district said no written schoolwide policy at the time barred that, and that after the work was submitted the principal independently scored it. The resulting course grade, MNPS said, was "the mathematical result" of that score, not a number chosen to produce a particular outcome. It "would not be accurate," the district said, to describe the episode as simply changing a grade at a parent's request, and it cited federal student privacy law in declining to say more about the student.
Grades were not her only complaint. Hardcastle described large classes and persistent discipline problems, estimating a class size of about 1 to 35 with several students per class posing serious behavior issues. She said the protocol was to call parents first, that write-ups could not be fully documented because it would reflect badly on the school, and that teachers were pressed to keep disruptive students in the room. Teaching under those conditions, she said, was close to impossible.
The district said it had "no evidence that this allegation has been substantiated" at Kennedy Middle or across the system, and pointed to recent investments in positive behavior supports meant to address problems before they escalate. For context, John F. Kennedy Middle enrolls about 747 students and is one of 164 schools in a district that serves roughly 81,500 students, according to federal data. The district's overall student-teacher ratio is close to 21 to 1, though that figure counts all teaching staff and typically runs lower than the size of an individual core class.
Hardcastle also said about $500 went missing from a paycheck, enough to put her behind on her mortgage, and that an email suggested the money went to pay other employees. MNPS said it was not aware of the specific circumstances but found no evidence that it withheld or clawed back pay to compensate other staff, that she was paid the gross amounts owed based on salary and attendance, and that the issue might instead involve required tax withholding on a state-funded teacher bonus.
At the board meeting, members did not respond to her statement beyond urging her to email them. Hardcastle said she has no interest in doing so, doubting she would get a genuine reply. She said most of the Metro teachers who contacted her after her post went viral told her they share the same concerns, and that she hopes parents across the district start asking questions.
Her exit lands amid a wider retention problem. A June 2026 report from the National Education Association found that Tennessee had the largest percentage drop in its teacher workforce of any state between the 2023-24 and 2024-25 school years, losing about 10% of its educators, more than 7,400 teachers. The tension she describes, between holding a line on grades and the pressure to keep students and parents satisfied, is one we have written about in the debate over whether teachers should be allowed to fail students.
