• The evaluation team selected measures that have a strong track record of use in other studies. The full technical report includes data on the psychometrics of the instruments so readers can judge the reliability of the measures. • It is noteworthy that impacts were found with different types of measures—standardized instruments (such as the Woodcock Johnson III and the adapted PPVT), parent reports (like the ratings of aggressive behavior), and live observations (ratings by the interviewers).
