First, you got your hands on some outdated information somewhere. There are 19 osteopathic medical schools.
Also, as far as ratings... I must ask, ratings for what? This is not an easy question because there are a million criteria that could be used to assess the different schools. Just some of the criteria could be:
* Stats of matriculants.
* Percentage of primary care physicians produced.
* Acceptance of minorities.
* Board exam scores.
* Student quality of life.
* Number of full-time faculty.
* Rotation sites.
* Research exposure.
* Early clinical exposure.
* Residency placement.
* Opportunity for extracurricular involvement.
* Tuition.
You see, it is a difficult to decide on which criteria to use and how much weight to assign to the different criteria. I recommend to others that they write the schools they are interested in, get some fact sheets, read some books that have statistics on different medical schools and begin to formulate your own criteria. For me, my own criteria includes such subjective things as "Proximity to family" and "geriatric opportunities." It is time consuming to do this, but somewhat enjoyable. Best of all, the school you will decide on will be the school that fits YOU best, not the school SOMEONE ELSE thinks is best.
Please jump out to the "Everyone" forum and read my response to this same question.
