I think what WisNeuro is alluding to is the preponderance of sub-par training programs that also happen to be Psy.D. programs that also happen to be at poor reputation and sometimes predatory programs. The study and application of I/O Psychology requires a strong basis in statistics, research methods, and similar skillsets, though most/all of those same programs de-emphasize these areas as to not scare away the "statistics are icky" applicants. It doesn't make sense to offer a more "clinically focused" degree in I/O because of the nature of the work. It's just more marketing.
In contrast,
HERE is a publication by well-respected experts in I/O that looks at rankings of programs (NOT using the US News & World Report approach). The publication is from the early 2000s, but most/all of those programs are still very well respected and where the vast majority of the private sector go to recruit top talent. I'm familiar with UMich, Mich State, and UMD…and this is how they do it.
