Once in kindergarten, Rose began throwing violent tantrums at home. She repeatedly watched a scene from the film “Finding Nemo” in which a shark batters its way into a tiny room, attempting to eat the main characters. The school provided no explanation or solution. Finally, on Jan. 6, 2006, a school aide called saying that Rose had taken off her clothes. We needed to come get her.

At school, her mother and I found Rose standing alone on the cement floor of a basement mop closet, illuminated by a single light bulb. There was nothing in the closet for a child — no chair, no books, no crayons, nothing but our daughter standing naked in a pool of urine, looking frightened as she tried to cover herself with her hands. On the floor lay her favorite purple-striped Hanna Andersson outfit and panties.

Rose got dressed and we removed her from the school. We later learned that Rose had been locked in the closet five times that morning. She said that during the last confinement, she needed to use the restroom but didn’t want to wet her outfit. So she disrobed. Rather than help her, the school called us and then covered the narrow door’s small window with a file folder, on which someone had written “Don’t touch!”

We were told that Rose had been in the closet almost daily for three months, for up to an hour at a time. At first, it was for behavior issues, but later for not following directions. Once in the closet, Rose would pound on the door, or scream for help, staff members said, and once her hand was slammed in the doorjamb while being locked inside.

At the time, I notified the Lexington Public Schools, the Massachusetts Department of Children and Families and the Department of Mental Health about Rose and other children in her class whom school staff members indicated had been secluded. If any of these agencies conducted a formal investigation, I was not made aware of it.

Rose still has nightmares and other symptoms of severe stress. We brought an action against the Lexington Public Schools, which we settled when the school system agreed to pay for the treatment Rose needed to recover from this trauma.

The physical and psychological injuries to children as a consequence of this disciplinary system is an issue that has found its way to Congress. Legislation to ban these practices has been introduced in the House and the Senate, but no vote is expected this year.

Meanwhile, Rose is back in public school and has found it within her to forgive those involved in her case. “They weren’t bad people,” she told me. “They just didn’t know about working with children.”
