Subtests for Wechsler Preschool and Primary Scale of Intelligence

The WPPSI–III is composed of 14 subtests.

    * Block Design - While viewing a constructed model or a picture in a Stimulus Book, the child uses one- or two-colour blocks to re-create the design within a specified time limit.
    * Information - For Picture Items, the child responds to a question by choosing a picture from four response options. For Verbal Items, the child answers questions that address a broad range of general knowledge topics.
    * Matrix Reasoning - The child looks at an incomplete matrix and selects the missing portion from 4 or 5 response options.
    * Vocabulary - For Picture Items, the child names pictures that are displayed in a Stimulus Book. For Verbal Items, the child gives definitions for words that the examiner reads aloud.
    * Picture Concepts - The child is presented with two or three rows of pictures and chooses one picture from each row to form a group with a common characteristic.
    * Symbol Search - The child scans a search group and indicates whether a target symbol matches any of the symbols in the search group.
    * Word Reasoning The child is asked to identify the common concept being described in a series of increasingly specific clues.
    * Coding - The child copies symbols that are paired with simple geometric shapes. Using a key, the child draws each symbol in its corresponding shape.
    * Comprehension - The child answers questions based on his or her understanding of general principles and social situations.
    * Picture Completion - The child views a picture and then points to or names the important missing part.
    * Similarities - The child is read an incomplete sentence containing two concepts that share a common characteristic. The child is asked to complete the sentence by providing a response that reflects the shared characteristic.
    * Receptive Vocabulary - The child looks at a group of four pictures and points to the one the examiner names aloud.
    * Object Assembly - The child is presented with the pieces of a puzzle in a standard arrangement and fits the pieces together to form a meaningful whole within 90 seconds.
    * Picture Naming - The child names pictures that are displayed in a Stimulus Book.
