1.    Identify the descriptive classifications of the FSIQ, Index scores, and subtest scaled scores.
2.    Interpret Jackie’s Index composite scores and describe what each Index measures. Use the following interpretation of the FSIQ as the format for your answers.

The Full Scale IQ (FSIQ) is an estimate of global intellectual functioning. Jackie’s FSIQ is 97, which is within the average range of intellectual functioning. She scored at the 42nd percentile, which means that her score is equal to or exceeds approximately 42% of the national comparison group.
