A pilot study for standardizing Woodcock-Johnson Cognitive and Achievement Tests in Arabic
DIRASAT. 42(2), 499-515.

This study examined the validity, reliability, and acceptability of the Arabic version of the Woodcock-Johnson Cognitive and Achievement Tests (WJ III; Woodcock, McGrew and Mather, 2001, 2007; Woodcock, McGrew, Mather, and Schrank, 2003, 2007) for Jordanian students. The WJ III is one of the most widely used tools across the world because of its distinguished features in measuring cognitive/ intellectual and achievement abilities. This pilot study had four major phases: Forward-backward translation and developing tests' items, training of the examiners, pilot standardization/ data collection, and calculation of validity and reliability coefficients. A total sample of 288 students aged 4 to 22 years old from schools and universities participated in the study. Results indicated that the Arabic WJ III Tests are valid, reliable, and may be used with confidence to predict students' academic achievement in Jordan.
