<p>^^^ RateMyProfessor is a service where students self report what they thought about their professors - this service has only been around for about 8 years so it is using recent students to give a grade. Who’s Who in America is a paid service where you can self nominate, or even if you are “outside” nominated the individual has to pay a fee to be included, that category would be using much “earlier” grads who supposedly - since you can buy your way into publication - have made a name for themselves, so again this category that CCAP is using is essentially self reporting. Given that 50% of the evaluation is based on self reporting the listing is not all that much different from any other list.</p>
