Professional licenses and certifications as supporting evidence — what I learned about their limits

Had a professional license in my field and initially thought it would carry more evidentiary weight than it actually did on its own. Worth sharing the limitation I learned, since I suspect others make the same assumption. A license or certification generally establishes that you meet a baseline professional standard to practice — it's a credentialing bar, not typically evidence of extraordinary ability by itself, similar to the distinction in the community post here about membership requiring genuine outstanding achievement versus just paying dues. Most licenses are held by a large population of competent practitioners, which is exactly what makes them weak standalone evidence of being at the very top of the field. Where it did help: as supporting context establishing my qualifications and legitimacy in the field, alongside the actual evidence of extraordinary ability (awards, contributions, recognition) doing the real evidentiary work. I'd treat a license the way I'd treat a degree — necessary context, generally not itself the centerpiece of any specific criterion.
