Um, we NEVER call it PTK. We are Phi Theta Kappa (ΦΘK) NOT Rho Tau Kappa (PTK).
From ptk.org/chapters/resources/pdfs/crm4.pdf "Proper Use of the Name The full name of the organization is the Phi Theta Kappa International Honor Society. Members of the organization should be referred to as “Phi Theta Kappa members” or “Phi Theta Kappans.” “Kappans,” “Phi Thetas,” or any other abbreviated version of the name are incorrect references. By the same token, the organization should not be referred to as PTK, as these are not the equivalent letters for the Greek words meaning wisdom, aspiration and purity. When abbreviating, the true Greek letters should be used (ΦΘK). Otherwise, “Phi Theta Kappa” should be spelled out."
