A specific recommendation of the new Standards for Educational and
Psychological Testing is that test publishers report estimates of the
conditional standard error of measurement. A procedure has been developed
for calculating conditional standard errors of measurement of composite
scores from a single test administration. The method is based on the Item
Response Theory (IRT) and will be illustrated using the Wechsler
Preschool and Primary Scale of Intelligence-Third Edition.
