Which of the following is an example of a Class I violation?

A Class I violation refers to a serious breach of regulations that poses a significant risk to the health, safety, or well-being of children in a child care facility. In this context, the situation where a child was not adequately supervised and left the facility premises is a clear example of such a violation. This category of violation relates directly to the safety of children; if a child wanders off unsupervised, it creates an immediate and profound danger, as the child could be exposed to various hazards or become lost.

The other situations presented, while certainly significant issues, do not reach the level of risk associated with the first scenario. Insufficient supervision leading to a child leaving the premises is critical because it can have immediate life-threatening consequences, which is the hallmark of a Class I violation. Ensuring that children are adequately supervised at all times is fundamental to the operation of safe child care environments.
