Reliability Reliability was assessed both through IRT standard errors and classical test theory Cronbach’s alphas. All tasks had acceptable CTT reliabilities, Cronbach alphas ranged .69 to .90
Criterion validity Insufficient data in the public domain to evaluate
Construct validity The individual measures generally were related to two broad mathematics tasks (the Woodcock-Johnson III Applied Problems and Calculation tasks) given a year later suggesting that the individual measures were also measuring part of the broader construct.
Concurrent validity All tasks except Cardinality were significantly correlated with the same tasks given a year later
