01 What this is

A validated developmental measure, in the open.

AbilityScore® is a 0–100 developmental measurement used across the field's largest clinical estate. Its evidence base is two peer-reviewed, open-access deposits: the methodology that defines the measure, and an independent validation protocol — reference BHCL-VAL-2026-001 — carried out with an independent contract research organisation, Manentia Research.

In validation, AbilityScore was compared against four established instruments — Vineland-3, CARS-2, Bayley-4 and ABAS-3 — on a clinical cohort of 300, with a 60-participant test–retest sub-study.

03 Findable by machines

Described once, discoverable everywhere.

This page carries machine-readable descriptions in three complementary vocabularies, so the evidence surfaces in the catalogues that scholars and governments actually use.

• schema.org Dataset — indexed by Google Dataset Search alongside Zenodo, Dataverse and government data portals.
• W3C DCAT — the catalogue vocabulary harvested by the European Data Portal and national open-data catalogues; aligned with INSPIRE, ISO 19115 and SDMX, the statistical standard used by the WHO, the UN and the OECD.
• FAIR Signposting — typed cite-as, describedby, author and license links, so machine clients reach the DOI, the metadata and the licence directly.
