The standardization data for the California Verbal Learning Test-Children's
Version (CVLT-C) were used to evaluate statistically significant discrepan
cies between key quantitative variables of this instrument, as well as the
base rate of specific discrepancies. The results indicated that apparently
large discrepancies between the respective standard scores were actually Fa
irly common. However, for 3 of the 4 contrasts, discrepancies that equaled
or exceeded 1.5 z-score points in the hypothesized direction were sufficien
tly unusual to be considered clinically significant. For a 4th contrast, di
screpancies that equaled or exceeded 1 z-score point in the hypothesized di
rection appeared to meet this criterion. It is suggested that the interpret
ation of clinically obtained CVLT-C profiles should focus primarily on spec
ific quantitative variables, with inclusion of consideration of the present
ed base rates of discrepancies between the respective z scores.
