Fetal Alcohol Spectrum Disorder
Standardised tools for assessing FASD in early childhood
FASD has no single diagnostic test. Assessment uses multidisciplinary frameworks — the University of Washington 4-Digit Code, Canadian (Cook 2016), Hoyme/IOM and CDC criteria — integrating growth, the three sentinel facial features, prenatal alcohol exposure and a neurodevelopmental profile measured with tools such as Bayley, Mullen, Vineland and NEPSY-II.
FASD rarely announces itself with one finding — it emerges from a structured cross-check of growth, facial morphology, neurodevelopment and prenatal history.
In short
No single test diagnoses Fetal Alcohol Spectrum Disorder. Diagnosis rests on validated multidisciplinary frameworks — most commonly the University of Washington 4-Digit Diagnostic Code, the Canadian (Cook et al., 2016) guidelines, the Hoyme/IOM revised criteria and the CDC/NTFAS guidelines — each combining growth metrics, the three sentinel facial features, prenatal alcohol exposure history and a profile of CNS/neurodevelopmental impairment.The assessment toolkit
Diagnostic frameworks anchor the work: the 4-Digit Code ranks growth, phenotype, CNS and exposure on independent 4-point scales; Canadian and Hoyme criteria standardise facial measurement (palpebral fissure length against norms, smooth philtrum and thin vermilion on the Lip-Philtrum Guide).Neurodevelopmental measures supply the CNS domain. In early childhood, clinicians typically draw on the Bayley Scales of Infant and Toddler Development for cognition, motor and language; Mullen Scales of Early Learning; Vineland Adaptive Behaviour Scales for adaptive function; and NEPSY-II subtests as the child matures. Sensorimotor, speech-language and executive-function screens complete the profile.
No instrument substitutes for documented prenatal alcohol exposure and dysmorphology examination — the tools quantify impairment; the framework integrates it.
The Pinnacle way
At Pinnacle Blooms Network, a clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or checklist. Our FASD pathway pairs structured neurodevelopmental measurement with occupational therapy and the clinician-administered AbilityScore®.Trusted sources

What to watch
Documented prenatal alcohol exposure, growth deficiency, the three sentinel facial features, and a neurodevelopmental profile that is disproportionate to environment or genetics.
Try this at home
When prenatal alcohol exposure is uncertain, record what is known objectively and proceed with the neurodevelopmental profile — impairment can be measured even while exposure history is being confirmed.

Frequently asked
Is there one definitive test for FASD?
No. FASD is diagnosed through a multidisciplinary framework that integrates growth measures, the three sentinel facial features, documented prenatal alcohol exposure and a neurodevelopmental profile — no single instrument is sufficient.
Which neurodevelopmental tools suit early childhood?
In infancy and toddlerhood the Bayley Scales of Infant and Toddler Development, Mullen Scales of Early Learning and Vineland Adaptive Behaviour Scales are commonly used, with NEPSY-II subtests added as the child matures.
Can FASD be diagnosed without confirmed alcohol exposure?
Some frameworks (e.g. Hoyme/Canadian) allow diagnosis when the full facial phenotype and characteristic impairment are present even if exposure is unconfirmed, but documented exposure strengthens diagnostic confidence.
