How is the Stanford-Binet Scored?

The Stanford-Binet® V (Stanford-Binet Intelligence Scales®, Fifth Edition) measures a student’s nonverbal and verbal abilities in five different areas:

  • Fluid Reasoning
  • Knowledge
  • Quantitative Reasoning
  • Visual-Spatial Processing
  • Working Memory

Here are all the standard IQ Score ranges for the Stanford-Binet:

  • Low average: 80-89
  • Average: 90-109
  • High average: 110-119
  • High achiever: 120-129
  • Moderately gifted: 130-144
  • Highly gifted: 145-160+

The SB5 normed total and subtest scores included on your child’s report are:

  • Nonverbal IQ (NVIQ) – this is the normed combined score taken from the five nonverbal subtests.
  • Verbal IQ (VIQ) – this is the normed combined score taken from the five verbal subtests.
  • Full Scale IQ (Full Scale Intelligence Quotient, or FSIQ) – this is the normed combined score taken from all 10 subtests.
  • Fluid Reasoning – measures a student’s ability to use inductive or deductive reasoning while solving both verbal and nonverbal problems.
  • Knowledge – assesses your child’s understanding of general information, vocabulary, social behavioral standards, and common sense that kids within the same age range are also expected to know.
  • Quantitative Reasoning – assesses an individual’s abilities with basic math concepts (such as identifying numbers and solving math word problems) as well as patterning, sequencing, ordering, classifying, comparing, and numerical problem-solving skills.
  • Visual-Spatial Processing – measures each student’s ability to identify patterns, relationships, spatial orientations, and how individual pieces relate to whole images on display as well as solve problems using pictures, images, diagrams, geometric shapes, maps or tables.
  • Working Memory – assesses a child’s ability to access information he or she has just seen or heard and how that data is inspected, transformed or sorted when answering a question or solving problems, such as repeating number and letter sequences in order, tapping blocks in a predetermined pattern or identifying visual and verbal absurdities shown on the test.
  • Percentile Rank (PR) – School districts use this number to compare each student’s individual test performance against a nationwide sampling of students born within the same three-month age range. A percentile rank of 80 means that child’s score was higher than 80% of students tested nationwide, and the PR ranges from 1-99.

IQ 99/ Letter-word identification= 71 what is the interpretation of these results

Sam says:

Hi Silva,

For the most accurate interpretation of results, you’d want to contact the administrator of the test or a psychologist to interpret them for you!
