Superintendent Wayne Walters said in a statement that officials wanted to "provide teaching and learning environments that support varying responses to trauma," and the gradual re-entry would allow staff and students "time to process and seek assistance as needed."

Pennsylvania students will return to Pittsburgh Westinghouse Academy 6-12 following a shooting that injured four people.

Police said a 17-year-old youth, two 15-year-old boys and a 15-year-old girl sustained wounds to their hands and other extremities in the shooting outside the school as students were being dismissed Tuesday afternoon. All were taken to a hospital — three by paramedics and the fourth by a relative — and all were said to be in stable condition.
