No, I don't think so.
But the (continuous) learning culture in the software industry and the developer sub-culture is not good.
Also I have the impression that in the last 2 decades a lot of people took software development adjacent technical degrees (specifically electrical engineering and computer science) who were in love with the economic prospects but would rather not put in the effort (specifically not after the degree).
Furthermore tests and examinations cannot do much against intelligent people just wanting to beat the system (and largely wanting to avoid becoming scientists of some kind).
Like in software development you cannot "test away" the "bad apples" and unfortunately when the (economic) stakes are high there is a lot of incentive to try to become (for example) a computer scientists even if you don't like the subject (and are correspondingly disengaged).
