I am currently a 2nd year DO student at DMU an we are in process of undergoing our 3rd year matches for rotation sites as well as 4th year clinical rotation explanations. Here is the run down!! 3rd year allows the student a couple different options, it is a year set up with mainly core rotations, meaning that no matter where you end up the year is scheduled with your primary care, surgery, OB/GYN and other "core" rotations, within the 3rd year there are 2 elective rotation options that can be done anywhere the student feels they would like to go, these are researched by the student, but secured by the clinical affairs staff who are at the students disposal during the clinical years, and are great at what they do! Timing as well as other student demand may not allow a student to rotate at a specific site, so the earlier you know where you want an elective to be, the better chance of rotating there! 4th year as I understand it now is basically the opposite of 3rd, there are about 8 four week elective rotations and only 2 core rotations, again the student needs to "search them out" however the staff at DMU will be in charge of contacting and securing the position, so you don't need to do any real leg work outside of deciding where and when you want to go somewhere, again there will be many of factors at play regarding whether or not you get a spot for elective rotations, such as timing, when you apply, preference for specific in state schools as well as DO vs. MD in some very few instances, it will all depend on where you want to go and when you want to do it, so I suggest during those times you plan well in advance, or as much as possible and try to secure those sites soon. Regarding DMU 3rd year options, each year will change as sites are always changing, the nice thing is that the school offers a few choices of state and city options for 3rd year, most of the class will stay in the Central Iowa Core Rotation, upon my understanding, this places rotations at no more than 2-3 hour drive from Des Moines, and many of the sites that are farther away do provide housing for you, however that is not a constant thing, and if you stay in Des Moines I believe it is assumed you will stay in the apartment or home you are currently renting. Any other site such as Michigan, Ohio, Missouri, and other states are year long core sites, so you would pick up and move to that city and live for the 3rd year and do core rotations, again housing is not necessarily provided and most students have to rent an apartment or home for the year, the specifics change a bit from time to time, I hope this was helpful and if you have any other questions just let me know!!
