The Stanford Binet (Early SB5) is individually administered and tailored to assess the general thinking and reasoning skills of children aged two years to seven years, three months. The complete scale, the Full-Scale IQ, consists of 10 subtests. There is one non-verbal subtest for each of the five factors and one verbal subtest for each of the five factors.

Skills assessed with Stanford Binet (Early SB5)

• The Fluid Reasoning score: the ability to solve verbal and nonverbal problems using inductive or deductive reasoning
• The Knowledge score: the accumulated fund of general information acquired at home and preschool. It involves learned material, such as vocabulary, that has been acquired and stored in long term-memory.
• The Quantitative Reasoning score: competence with numbers and numerical problem-solving, both with word problems and picture relationships
• The Visual-Spatial Processing score: the ability to see patterns, relationships and spatial orientations among diverse pieces of a visual display
• The Working Memory score: the memory processes in which diverse information stored in short-term memory is inspected, sorted or transformed
• The Nonverbal IQ score: based on the nonverbal subtests of the five-factor index scales.

The Verbal IQ score provides a measure of the cognitive skills required to solve the items in the five verbal subtests. The Full Scale Intelligence Quotient (IQ) is derived from the sum of all the tasks in the Early SB5.

The Early SB5 Full Scale score is one way to view a child's overall thinking and reasoning skills. As a battery of cognitive tests, the SB5 advances the assessment of strengths and weaknesses in the cognitive processes of students who may be evaluated for learning disabilities. The SB5 supports the early prediction of emerging learning disabilities in children as young as four years old.
