Transcript of WISC-IV

WISC I-IV (Wechsler Intelligence Scale for Children)
Sub-test Information
(based on 1949 WISC)
-General Information
-General Comprehension
-Picture Completion
-Picture Arrangemant
-Block Design
-Object Assembly
-Coding or Mazes
Advantages and Disadvantages
-IQ test provide a profile of the student’s strengths and weaknesses
-Reveals many unsuspected talents of many students
-IQ test does not do justice to the multi-dimensional nature of a child’s intelligence
-The knowledge of a student’s IQ may inhibit their level of aspiration and affect their self-confidence
-Likely to cause frustration or anxiety if a student cannot complete the tasks, especially ELLs.
David Wechsler
(January 12, 1896 – May 2, 1981)
What Is It?
The Wechsler Intelligence Scale for Children (WISC) is an intelligence test that is administered to children ages 6 to 16. It can be completed with or without the student’s reading ability. Currently, within the WISC IV, there are 16 subsets to the test. WISC generates a child’s IQ score, which therefore represents their cognitive ability. A school psychologist is most likely to be the person who administers the test. The WISC has been translated and used across the world in many languages and countries. The cost of the WISC IV Basic Toolkit is $1,069.00.

Administration Time
60-80 minutes for the entire test, depending on the child.
Students between the ages of 6 and 16.
The first WISC test was administered in 1949. There were then updates in 1974, when the test was renamed WISC-R. It was again updated in 1991 to become the WISC-3. In 2003 it was changed to the most recent version of the WISC-IV. It will again be updating in Fall of 2014 to become the WISC-V. All of the updates included changes to the questions and pictures to make them less biased, by having the pictures come to fit the times (and are colorful), as well as having the names of individuals become more multiculturally aware.
David Weschler was a leading American psychologist. He developed the well-known intelligence scales, such as the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC).

How is the WISC administered and scored?
The test is administered in a standardized manner to enhance reliability and maintain consistency (ex. The instructions are read out verbatim from the test manual and the core subtests are administered in the same order). Every psychologist recites the same instructions and administers the core subtests in the same order for each child he/she assesses.
After scoring the subtests, raw scores are derived by summing the number of correct items within each subtest. These raw scores are converted into scaled scores which are comparative within the child’s own age group. Scaled scores allow a child’s abilities to be compared with the typical performance of others that age. The scaled scores for each Index are then converted into IQ scores which can be directly comparable across age groups.

The IQ classifications are as follows:

Very Superior- 130 and above
Superior- 120-129
High Average- 110-119
Average- 90-109
Low Average- 80-89
Borderline- 70-79
Extremely Low- 69 and below
