Purpose: The Woodcock-Johnson III Diagnostic Reading Battery's designation is for assessment and measurement of the important dimensions of phonological oral language abilities and phonological awareness, both in adult and children.
Population: Both adults and children (age of 3-80 years).
The Woodcock-Johnson III Diagnostic Reading Battery is for the assessment and measurement of the important dimensions of phonological oral language abilities and phonological awareness, in both adult and children (Brande, 2008). By utilization of software scoring and the paper-and-pencil assessments, the test serves to determine the general level of literacy in both the young and the old generations. The computer screen display of words and the letters are useful in determining an individual's level of word-letter identification, basic reading skills, reading fluency and total reading skills. The test validity ranges between the coefficients of 49 to 53, the discriminate validity, construct validity and convergent validity (Fredrick, Nancy & Woodcock, 2004). The test is useful in the identification of the Attention Deficit, proficiency and the overall literacy of an individual. Moreover, the test may help in the determination of a person's attitude towards reading or interaction with written materials hence, the reliability of this test is substantially uncompromised.

MSCA has been one of the best tests ever produced to measure and assess children's intelligence and abilities. Longitudinal studies on this test elicit that MSCA is functional in the evaluation of early interventional effects of children's development worldwide. The study reveals that children from different demographics and contexts pursue substantial cognitive, health, behavioral, and schooling gains from the interventions of early childhood (McCarthy, 1982). One of the subsequent study reviews used the MSCA scale to demonstrate the beneficial effects of parental cognitive inspiration and the emotional support to their children's cognitive abilities. Nevertheless, the reviewer compromises the validity of this test, in that; it measures much of the cognitive abilities rather than children's intelligence.
This test has been useful in the evaluation of nutritional supplement effects provided to nursing mothers to develop their nursing infants, realize the effects of air pollution on a child's cognitive developments, as well as the early intervention effects on the infant's pattern of development. Generally, the psychometric scale properties are appealingly admirable, with factorial validity evidence and predictive validity (Schultz & Duane, 2009). On the other hand, the reliability coefficients in the overall cognitive index tend range in 90s, and the validity data extremely encourages.
