I'm confused. I have read that there are only 8 NPHC fraternities/sororities (Alpha Phi Alpha, Omega Psi Phi, Phi Beta Sigma,the great Kappa Alpha Psi, Alpha Kappa Alpha, Delta Sigma Theta, Sigma Gamma Rho, and Zeta Phi Beta)but, what about Iota Phi Theta and Groove Phi Groove fraternities and Rho Alpha Pi sorority? Why aren't they apart of the "8"?

Also, if there are any members of these "3" out there, how do you feel about not being included in the "8"?
