Throughout this white paper from BARBRI, found by Lisa Solomon, you find the Dunning-Kruger effect at work. For example:

82 percent of 3L law students believe they are effective legal writers. In contrast, only 57 percent of practicing attorneys who work at companies that hire recent law school graduates believe recent law school graduates are effective legal writers.

It continues:

71 percent of 3L law students believe they possess sufficient practice skills. In contrast, only 23 percent of practicing attorneys who work at companies that hire recent law school graduates believe recent law school graduates possess sufficient practice skills.
