Features and benefits

  • Includes six domains:
    • General Information (GI): the learning of cultural knowledge, much of which is not explicitly or directly taught.
    • Comprehension (CO): the knowledge of social behavior, "common sense," and the ability to interpret sayings and proverbs.
    • Quantitative (QN): the ability to do mental calculations, remember essential numbers, and determine the arithmetic process required to calculate correct answers.
    • Similarities and Differences (SD): the skill in determining common attributes of two dissimiliar things or concepts and some uncommon attributes.
    • Vocabulary (VO): the ability to use, understand, and define words orally.
    • Auditory Memory (AM): the capability to remember and repeat correctly a random series of digits, both forward and backward, as well as several sentences.

    The SIT-4 yields a Total Score, charts category scores, and compares ability to achievement.
