In the past, schools didn’t have to advertise. Students just moved into a district, registered and showed up on the first day. Times have changed, however, and public schools are recognizing that. In an era of school choice, where traditional public schools compete with competition from charters and private school vouchers, students are being siphoned away. In North Carolina, for example, Durham Public Schools has lost 1,000 students in four years, while enrollment in area charter schools grew by 1,700.
