Fair enough GavinC. I am asking in terms of education and then looking at factors like how the program is respected by colleagues.
On a broad basis, programs that pay their residents are generally more respected than ones where the residents have to pay. That is directly related to the concept that better residents will be able to match to a program that pays them, rather than having to pay upwards of $50k/year to attend pedo.
There is undoubtedly some truth to that concept, but not always.
If you wanted to work for me as an associate, I would need to know that you graduated from an accredited pedo program, but the most important factors to me would be your work ethic, your speed, and your rapport with the patients and parents. Whether your went to the east coast, west coast, did lots of hospital training, or had to pay for your residency wouldn't really be on my radar.
Having said all of that, I've never met a colleague who voiced a greater amount of respect for one program over another. This includes faculty and colleagues in residency, local pediatric dentists, and others at annual meetings. The topic simply never comes up, which is why I think nobody cares. A prestigious law school will open doors for you to join large firms, but there are no real and pronounced benefits to attending one pedo program over another, assuming you have the desire to work hard and learn as much as you can.
The ONLY benefit might be networking by attending a pedo program in the location where you want to practice.
