This is an interesting discussion (regarding specialization, tracking, etc.) and I appreciate the variety of perspectives that have been shared.
Having not attending veterinary school as of yet, I'm not in a position to comment as to whether or not the current organization structure of a DVM curriculum best prepares students for the complex professional demands that they'll face upon graduation.
As I'm fairly certain of the path I'd like to take post-graduation (lab animal), I also recognize that people change their minds upon exposure to different fields. That's what school (especially at the introductory level) is all about. I think it's a bit unrealistic to expect a student at 21 years old to know, beyond doubt, exactly what they want to do for the duration of their professional career. For some, this may be exactly how their career progresses. They set a goal, attend veterinary school, and follow the exact plan they had set for themselves when they were 20. This trajectory is not, however, true for all- and I would venture to say likely not true for most (this certainly hasn't been the case with my career).
Although I support tracking and the opportunities it presents for students to obtain additional, specialized exposure to their chosen field of interest (at least at the time), I also recognize the chief importance of having a broad understanding of one's field. Although I'm not yet a clinician, I can speak from experience in other realms of science. Specialization without context can be a dangerous road to travel- not only from a technical standpoint, but also for lack of appreciation for the work your colleagues (in different areas of vet med, or any other discipline for that matter) perform. I don't mean lack of appreciation in terms of 'you don't think they perform good/important work,' rather, I mean that you don't necessarily see the commonality between your area of specialization and theirs. It reminds me of students on these boards who don't enjoy/want to take classes unrelated to vet med- like humanities and social sciences area a waste of time. All students are busy in their academic endeavors, especially those aiming to attend professional school. However, being so myopic that you can't appreciate stepping out of the science box and learning things about completely different disciplines can't be a good thing. A generalist education makes us all well rounded.
Again, I may be a bit out of my league here as I haven't yet attended (nor been accepted to vet school). However, can someone comment on what's flawed about the internship/residency program here in the US and abroad? Isn't this the way that specialization within vet med is typically obtained? Is the hesitation re: pursuing a residency related to the high debt load/low salary level associated with becoming a resident directly out of school? I always assumed that vet school was a generalist education, and that residencies were required to gain any specialization that a student sought.
As for me, I'm torn between pursuing tracking vs. non-tracking programs. I intend to apply to a split of both next year. On the one hand, I see the value in it for the reasons I stated above. On the other, I'm very much a 'forest' rather than 'leaves on a tree' kind of thinker. I want to gain exposure in fields that I'll likely never pursue personally (i.e. small animal emergency, food supply practice, etc.). Lab animal medicine is often described as 'the ultimate mixed animal practice, ' and this is certainly what I experienced during graduate school. Although the majority of biomedical research is conducted in rodent models, what about new directions of research being conducted in every major vertebrate clade, not to mention invertebrates. Who knows whether or not I'll be dealing with a cow for a research project one day? If that day comes, I'd like to have the confidence to say that I've at least been exposed and have a decent appreciation for the work a bovine practitioner performs.
Hope that I didn't step on anyone's toes here- that wasn't my intention. Just adding my 2 cents, and looking for some feedback on my thoughts/concerns.
