A: Thank you for your concern. All parents attending the Valentines party were greeted, asked for the reason of their visit and then buzzed in by the main office. At no time were the visiting adults unmonitored. With large events, we use a sign in and sign out at the location of the classroom event. There is no honor system. Classroom teachers notify the main office of who is expected and who actually attended. At no time are doors unlocked and not monitored.
