Official Evaluation

The validity and reliability of the Pib Speex have been systematically and comprehensively researched in various contexts. The test developers should be congratulated for the variety and extent of the validity and reliability studies included in the manual. An advantage of the Pib Speex is that situation-specific norms can be computer-determined. This is a great plus factor, which could increase the fairness of the decisions made in the selection contexts.
