Maybe a lot lot more. As Dan Way reports for Carolina Journal:

“We were expecting quite a few, [but 154] was not what we were expecting,” Joel Medley, director of North Carolina’s Office of Charter Schools, said of the huge volume of letters of intent received by the Jan. 4 deadline. Formal applications are due by noon, March 1. (Initial reports said 161 applications were filed, but that number was overstated because of a database glitch.)

“One of the things that we did not expect was as many as we saw in Mecklenburg County,” from which there were 30 applications, including the two virtual schools, Medley said.
