I think the comparison is quite fair, though I may look at things differently than jblil. Like all rating sites, there are two primary components to assess. The institution and the rater (student). First, let's look at the institution who governs the faculty. One, the board of directors are solely responsible for shareholders and investors. They do not have to allocate a certain percentage of profit back to the community nor have an established subcommittee to oversee such operations. The faculty may be good, but they will be leaned out, i.e., the least amount of experienced PhDs possible in lieu of specialists. I'm not discounting the clinical expertise of a specialist, but if all is equal, they do not replace a PhD who is also board certified. This would tell me that they practice and can translate their research to current clinical practice/relevance. Friendly, personable, or not. You do not need much $ to perform research on a learning basis, this tells me that they just don't have much experience teaching in that area. Students who volunteer their time to speak with applicants won't have anything negative to say 99% of the time. They're usually the top performers and it's academic suicide to do so.
This alludes me to the second component, the student. Most of these for-profits are "last chance" schools for most students due to low past academics, high acceptance rates comparatively, and locality. Cost does not seem to affect decisions for these students due to the applicants' yearning to join our profession (I don't blame them, we're currently the cool kids). Unfortunately, many of these students are academically unprepared for any healthcare profession and provide negative reviews when they do not succeed. Being a for-profit institution, faculty will be pushed to keep lowering their standards so that the loan $ keeps coming in. If not, they will find someone else who will. I see that in many of the nursing programs. PT will be no different in this business model.
