The nine organizations which comprise the NPHC have mandated that where there are two or more NPHC affiliate member chapters, a NPHC council should be formed. NPHC organizations are unique with respect to other Greek-letter organizations in that they have a profound commitment to providing community service and to uplifting and promoting the general public welfare.

Eight of the nine affiliate organizations are represented on the campus of Virginia Tech. They are all active and all thrive to seek improvements for the community in which they operate and beyond.
