The CPPS was normed on a sample of 1,121 children rated by 278 teachers from 128 communities in 30 states. The sample’s demographics closely match those of the U.S. population.
For the four normative age groups, the internal consistency reliability coefficients of the subscales range from .88 to .98, with the majority in the mid-90’s.
Validity support comes from high correlations with measures of processing skills, cognitive skills, and achievement, as well as factor analytic and developmental evidence.
LD Profile and Classification Accuracy
Compared to matched controls, LD subjects had significantly higher means on all subscales. The CPPS has high classification accuracy in regards to LD.
