The economy is going down the drain. The lack of funding for higher education (in general) has led to a decrease of seats, and an increase of tuition rates. The number of OT seats in higher education hasn't increased, despite the demand for OTs. Everything is getting harder to get into however, not just OT. An old professor of mine told me that a student with a 4.0 GPA and Great MCAT applied to 19 medical schools and didn't get in anywhere.
I have a 3.6 overall GPA, 3.7 science GPA, prereq GPA of 3.5-3.7, +800 total hours of observation and extracurricular stuff (all highly relevant to OT, including working as a rehab tech).
I've had 3 interviews, got rejected from the first school, waitlisted at the second, currently waiting to hear from the third school. I had another interview invite but declined because it was too far away, and I'm waiting on another school to review my application and possibly send me an invite.
The first two schools have seen large increases in the number of applications (+100-200 applicants within the past two admissions cycles, for a total of 600-800 applicants competing for just 35 seats). Needless to say, at those schools I am competing against people with 3.7-3.9 GPAs, with degrees in subjects like Neuroscience, who already have several years of experience in healthcare and are doing a career change.
I'm not sure about the other schools, but they have seen increases too. So yes, OT is now approaching the competitiveness of what PT and medical school once was (from my experience). I was told by an interviewer that the OT profession will be moving towards the OTD as the standard entry level degree, so OT is changing drastically.
If your GPAs aren't in the 3.7-3.9 range, you may want to focus on schools that receive less applicants. I decided to apply to and invest in highly competitive schools this application cycle when I should have broadened my options a bit more.
