<p>Actually, I have heard that, unlike many areas of engineering, no one cares about ABET certification for computer science. Apparently many of the top CS programs are not ABET certified. Some places, like Harvard, offer only a BA degree, but students can take the number of courses that would be required elsewhere for a BS. At Princeton, they offer both BA and BS degrees in CS, and say that the computer science content of the degrees is identical.</p>
