I'm a student at the Austin campus (and a tour guide lol). So the main drawback is that for profit = expensive, especially USA. However, the faculty is receptive to feedback and is able to get quick funding for new equipment and materials. For example, the Austin campus had 4 microwaves in the cafe a year ago; we complained about standing in line over our quick break between class to warm up our lunches, and now we have 8. We're building a giant simulation lab with a grocery store, hospital room, and another apartment (I think) and getting medical-grade dummies & hiring standardized patients for Mock lab. We have the SafeGait system attached to our fitness center so we can work with our professors doing research & providing treatment for people from the community. We're starting a club for OT students called TADA! (Technlology and design applications) to give us more practice with making adaptations. All of these use funding from our tuition and from private investors to help make this happen without having to get approved by the state or whoever.
All in all, I wouldn't necessarily say that there's a negative to attending a for-profit school aside from taking on some more debt. If you are able to go to a cheaper school with comparable opportunities for leadership & research & community outreach................................
