Placement rate can be a bit questionable. Iowa State when I was there ran darn near 100%, but not everyone got a very good job. They agressively brought in some desparate employeers. The Patent and Trademark Office, for example which needs to hire over five thousand patent examiners per year because the turnover rate is so high; they would make you an offer if you met two criteria: an earned engineering degree and a pulse... respiration is nice, but they have ventilators if necessary. But, if you've got student loans that you're gonna have to start paying on, any job is a good job.
A key thing to ask is how much the university will do for you for placement. For some of the recent grads I talked to last year, their school's placement program was little more than a cork board in the hallway with job announcements pinned to it. At ISU when I was there, to graduate in engineering you had to take and pass a zero-credit class (you got no academic credit for it but you had to pass it to get your degree) in how to get a job. And the placement office was very agressively. There wasn't a major engineering/technology company in the country that didn't come to ISU to interview twice a year. The engineering placement office was a well-run ship and a typical graduating senior would have thirty to fifty on-campus interviews... thirty to fifty. The services of that office are available to alumni for life... including on-campus interviews. Several alumni friends of mine in need of work... guys with ten or fifteen years of experience, have gone back to Ames for a a couple of weeks and had twenty interviews on-campus followed by eight or ten plant-trip interviews followed by two or three offers.
When between jobs myself, I sent my resume' to the ISU Engineering Placement office and it was only a matter of days before I started getting calls. I got one plant trip (a bizarre story I'll tell you over drinks at Bladeshow sometime) which did result in an offer which I declined, but an offer nonetheless.
So, find out what they do for graduating seniors and what they do for alumni.
