    Technical Qualities


    A test's validity depends on two factors: 1) how closely its norming sample represents the population to which the test results will be compared, and 2) how carefully the data were gathered from that sample. The WJ III sample was selected to represent, within practical limits, the U.S. population from ages 24 months to 90 years. Normative data for the test were gathered from 8,818 subjects in over 100 geographically diverse communities in the United States. Individuals were randomly selected within the stratified sampling design that controlled for 10 specific community and individual variables and 13 socioeconomic status variables. The sample consisted of 1,143 preschool subjects; 4,784 kindergarten to twelfth-grade subjects; 1,165 college and university subjects; and 1,843 adult subjects.

    The WJ III uses continuous-year norms to yield normative data at 10 points in each grade. It provides age-based norms by month from ages 24 months to 19 years and by year from ages 2 to 90 years. And it provides grade-based norms for kindergarten through 12th grade, 2-year college, and 4-year college, including graduate school.


    The WJ III DRB clusters show strong reliabilities, most at .90 or higher.

  • System Requirements


    The WJ III DRB Scoring and Reporting Program is included with each kit and provides several types of interpretative reports.

    • Summary Report — Communicates test results to teachers and other professionals.
    • Parent Report — Includes a profile of the subject's proficiency and a brief explanation that is useful for reporting the results of testing to parents.
    • Classroom Report — Profiles can also be printed that provide a graphic representation of the individual's reading performance. Profiles include instructional ranges for each cluster and test.
