The Covenant School (TCS) in Nashville, Tennessee, where at least three children and three adults were killed in a mass shooting on Monday morning, is a private Presbyterian school offering classes from preschool to sixth grade.

Metro Nashville Police Department officers killed the shooter, a 28-year-old Nashville woman and former student whose name has not been released.

"At one point she was a student at that school," Nashville police Chief John Drake said. "There was a vehicle nearby that gave us a clue as to who she was."

TCS has a goal "to educate twenty-first-century children in a way that prepares them to impact their culture and think in accordance with timeless Truth," according to a statement on its website from Covenant Head of School Dr. Katherine Koonce.

"When Carrie Underwood shows up to watch the 3rd and 4th grade musical about the Grand Ole Opry… it’s a REALLY good day, especially if you were the little girl who just played her on stage! Carrie even stayed to pose for pictures and sign autographs. We could not have asked for a better surprise for our hardworking students!" TCS wrote in a February 2022 caption.
