Re: WJ III Cog

Woodcock-Johnson III Tests of Cognitive Abilities is designed to measure, together with the WJ III Ach, intellectual abilities and academic achievement.

It expands the WJ-R Tests of Cognitive Ability (WJ-R COG) and is designed to measure general and specific cognitive functions.

The WJ III Tests of Cognitive Ability has uses for educational, clinical or research purposes.

As a diagnostic tool, it can determine specific strengths and weaknesses, and can help associate certain factors on future development.

Scales: Verbal Ability, Thinking Ability, Cognitive Efficiency, Supplemental, Intra-Cognitive Discrepancies, Predicted Acheivement and General Intellectual Ability (GIA)

Time: 60-70 minutes.

Scoring:

The WJ III COG provides two indices of general cognitive functioning (i.e., intelligence) by means of the General Intellectual Ability (GIA) score and the Brief Intellectual Ability (BIA) score.

Requires scoring during testing to determine basal and ceiling levels.

Raw scores are totaled and converted into age and grade equivalents, percentile ranks, and discrepancy scores with use of the Scoring Tables.

Compuscore and Profiles Program are used for all other scoring.

Reliability:

The median reliability coefficient alphas for all age groups for the standard battery of the WJ III COG for tests 1 through 10 ranged from .81 to .94.

For the Extended battery, median coefficients ranged from .74 to .97. The reliability scores for the WJ III meet or exceed standards.

The median cluster reliabilities are mostly .90 or higher, and the individual test reliabilities are mostly .80 or higher, and can be used for decision making purposes with support from other sources.

Validity:

The technical manual presents a considerable amount of evidence supporting the validity of scores from the test, noting that the earlier versions of the battery have also been shown to have validity.

Test content on the WJ III COG has emerged from previous versions, is similar to the content found on other well-established cognitive measures, or is based on sound experimental instruments.
