When Is Full Scale IQ FSIQ Invalid

1
When Is Full Scale IQ (FSIQ) Invalid?

• The Full Scale IQ is deemed invalid,
  non-representative or non-unitary when there is a
  clinically significant difference between the
  Verbal IQ and Performance IQ scores, between
  Indices and/or among the individual subtest
  scores within an Index.
• Discrepancy at the 0.10 significance level

Determining Training Potential Based on IQ

• General Guideline
• FSIQ
• 99 Formal (University)
• 89 98 Formal (College)
• 81 87 Informal
• ?80 Entry-level
• Note These values are approximates. Other
  factors that influence retraining recommendations
  include academic and aptitude profile, past
  education/training experience, a learning
  disability, and the clients attitude
  motivation.

Achievement TestWide Range Achievement Test
Fourth Edition

• Measure of previous learning instead of potential
• (WRAT-4) - A measure of an individuals academic
  achievement in Reading, Sentence Comprehension,
  Spelling and Math Computation
• Standardized according to age, similarly to the
  WAIS-III
• Standard score can be converted into a percentile
  score and a grade score, and given a qualitative
  description

WRAT-4 Scores

• Qualitative description of scores based on range
• 130 Very Superior
• 120-129 Superior
• 110-119 High Average
• 90-109 Average
