Stanford-Binet Intelligence Scales
SBIS vs the AbilityScore Developmental Assessment
The Stanford-Binet (SBIS) is a standardised IQ test estimating a child's cognitive ability against same-age peers, usually administered by a psychologist for a specific cognitive question. The AbilityScore® is a clinician-administered structured developmental assessment that maps everyday functioning across many domains and tracks progress against your child's own baseline. They are complementary lenses, not rivals — and a clinical AbilityScore® or any diagnosis is formed only at a Pinnacle Blooms Network centre under qualified clinician care.
You may have heard the Stanford-Binet name and wondered how it sits alongside the AbilityScore your Pinnacle clinician uses — they answer different questions.
In short
The Stanford-Binet Intelligence Scales (SBIS) is a standardised IQ test that estimates a child's cognitive ability — reasoning, knowledge, working memory — against same-age peers. The AbilityScore® is a clinician-administered structured developmental assessment that maps how your child is functioning across many everyday domains and tracks change against their own baseline. One gives a cognitive snapshot; the other gives a living, whole-child progress picture used to plan and measure therapy.How they differ — and where they overlap
Think of them as two different lenses, both useful in the right hands:- What they measure. SBIS focuses on intellectual ability and yields IQ-type scores across cognitive factors. The AbilityScore® looks broadly at developmental functioning — communication, social-emotional skills, daily living, motor and learning behaviours — to guide a practical plan.
- The question they answer. SBIS asks how does my child's cognition compare to other children their age? The AbilityScore® asks where is my child now, and how do we move them forward?
- How the result is used. An IQ score is largely a point-in-time benchmark, often part of an educational or diagnostic work-up. The AbilityScore® is designed to be repeated, so you can see progress session over session.
- The benchmark. SBIS compares your child to a normed population. The AbilityScore® centres on your child's own starting point — empowering, not labelling.
The two are complementary, not competing. A clinician may draw on cognitive findings (from an SBIS or similar) alongside an AbilityScore® to build a fuller, fairer understanding of your child.
When each is appropriate
A formal IQ measure like SBIS is usually considered when there's a specific question about cognitive ability — for school placement, certain diagnoses, or eligibility decisions — and is administered by a qualified psychologist. A developmental assessment is the right first step when your concern is broader: is my child developing as expected, and what support helps? That's where the AbilityScore® fits, opening the door to targeted therapy.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician — never from an online score or a single number. Our AbilityScore® is a clinician-administered structured assessment built on 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, measuring your child against their own baseline and turning insight into a clear plan. Explore what the AbilityScore is and how it's calculated, and see how findings shape child development therapy.Trusted sources
WHO ICD-11 framework on developmental functioning; AAP/HealthyChildren guidance on developmental surveillance and screening; CDC milestone resources; NICE guidance on assessing children's development and cognition. These describe IQ tests and developmental assessments as serving distinct, complementary purposes.Next step — Want a clear, whole-child picture?

What to watch
If your concern is broad — speech, social skills, play, daily living or learning behaviours — a developmental assessment is the right first step. A formal IQ measure like SBIS is considered for specific cognitive questions, school placement or eligibility, and is administered by a qualified psychologist.
Try this at home
Before any assessment, jot down a few real examples of what your child can and can't yet do day to day — words used, how they play, how they follow instructions. These everyday notes help a clinician build a far more accurate, kinder picture than any single number.

Frequently asked
Is the SBIS the same as the AbilityScore?
No. The SBIS is a standardised IQ test estimating cognitive ability against same-age peers, while the AbilityScore® is a clinician-administered structured developmental assessment that maps everyday functioning and tracks your child's progress against their own baseline.
Can my child have both an SBIS and an AbilityScore?
Yes — they are complementary. A clinician may draw on cognitive findings alongside an AbilityScore® to build a fuller picture, then use the AbilityScore® to plan and measure therapy progress over time.
Which one tells me if my child needs therapy?
A developmental assessment like the AbilityScore® is the right first step when your concern is broad development and support, as it directly guides a practical therapy plan. Any diagnosis is confirmed only by a qualified clinician at a Pinnacle Blooms Network centre.
Who administers each assessment?
A formal IQ test like the SBIS is administered by a qualified psychologist. The AbilityScore® is administered by trained Pinnacle clinicians as a structured developmental assessment.
