Note that the school districts in North Carolina are surprisingly big in the Census data.
Some counties have their own open data portal that contains schools and/or school districts.
Durham
This is a page where you can download the locations of Durham public schools (not the school districts) in many formats.
Johnston
This is Johnston Countys GIS page, if you scroll down to “Schools and School District” you can download the shapefiles.
Orange
This is an interactive map of Orange County where you can highlight the schools (could not find a link to download the file).
Wake
If you scroll down to “Miscellaneous” there is a file called Wake_Schools_year_mo.zip
