<p>The best source is to ask people who are knowledgeable in the field, ideally someone who does some hiring of people in that field. I’ve heard people say “We like to hire grads from x university, because they come out of college prepared to start working in the field right away.”</p>
<p>Another source is to look at the number of professors in the dept. Check to see how many are full-time staff and how many are part-time. Keep in mind that sometimes part-time people can make great teachers, if they have years of practical experience and are teaching because they enjoy it. However, if there are too many adjuncts who are running from college to college trying to earn a living, that can be a negative. Those teachers often won’t have time to get involved with students, and may not even have office hours.</p>
<p>If a college has recently hired profs for a dept., that is a good sign. If the dept. is shrinking through attrition (or layoffs), that can be bad.</p>
<p>Also, look at the courses that are ACTUALLY offered in a recent semester - NOT the full book of courses. Many colleges have books of courses that are authorized, but are never actually offered because of a shortage of teachers. You want to make sure that sufficient numbers of courses are offered so you have some choices and so you can graduate on time. Ask students whether they have trouble getting registered for classes. At many universities, freshman have trouble registering for popular classes, which is OK, but if upper classman can’t get in, that is bad.</p>
<p>You might also learn something by the building in which the dept. is housed. If a dept. is a modern building or an extensively renovated one, it tells you that the college values that dept. If the dept. is in the run down basement, that tells you something else.</p>
<p>You can google the “common data set” for most colleges. It will tell you the number of people who graduate each year with various majors.</p>
<p>Some majors may have a great reputation, but they are hard to get into. This is particularly an issue when a student picks a college for a major, but they require students to apply to enter that major after a year or two, and most people don’t get in.</p>
