To the Editor: We believe that several points
in the Special Communication by Dr Brennan et al1 deserve
comment. First, the authors show that certification examinations correlate
well with other measures of physician aptitude, but do not show that these
examinations are more accurate or precise than other tests of physician quality.
Tamblyn et al2 demonstrated that while several
indices of physician quality correlated with scores on a certification examination,
these indices were also correlated with testing done during medical school.
Other research indicates certification examinations add little to earlier
testing.3 We question the value of measuring
the same thing in multiple ways.
