I believe Ken 77 is referring to the Triangle Math and Science Academy. It opened in the fall of 2012. There's a separate thread about the school already:

I don't know anything about the school, but it does appear that some parents do have some concern; it might be worth PM'ing some of the folks in the thread for more information.
There is a list of applicant charter schools to open in the 2013-14 year at the state department of education website here:
Application and Resources
However, there's no quick way of seeing where each of these is located. You may need to open each one. I can say for sure that Longleaf School of the Arts will be in the Triangle, probably Wake County, and is a 9-12 HS focusing on the arts. Also, just yesterday, there was a press release that over 150 new charter school applications were received by the state Board of Education for opening in NC in the 2014-15 school year. This is state-wide, and preliminary applications only; none have been reviewed, and it's unclear how many of those will even move forward from the initial filing. Apparently something like 14 of them are in Wake County.
