The incident took place at Carrboro's Frank Porter Graham Elementary School, next to Kingswood Apartments, the home of the man charged with the crime.
Since the assault, a Chapel Hill police officer has patrolled the grounds of the school and numerous parent volunteers keep watch over children walking to and from classes.
Ross McGlothlin, assistant principal at Frank Porter Graham, said the school has recovered well from the incident.
"We have a very active PTA, and our PTA president-elect has been on the phone, calling parent volunteers," he said.
McGlothlin said that between 40 and 50 parents, including several UNC professors, have been acting as campus safety monitors since the incident.
"The parents are watching the children moving between class, looking for kids who get separated from their groups," he said.
And the way the children get from place to place has changed in response to the incident. "In the past, if an older child wanted to take a book to the library or get a Band-Aid from the office, they could go alone," McGlothlin said."Now, all children must be accompanied by an adult."
Despite the presence of a police officer at Frank Porter Graham, the bulk of school security is the responsibility of each individual school.
Chapel Hill police spokeswoman Jane Cousins said police officers don't station themselves on school campuses.
