I don’t have any insight to this specific program but I will tell you that in general, changes in programs are small and incremental, if at all. I say this having attended departmental meetings for near a decade.
Generally speaking, evaluations of a program from several years back are probably just as valid as they are today. In addition, little of those nuances matter, but most people don’t realize that until years afterwards. Most of what you get out of training is what you put into it. Anywho...
