Psychological resources · GAI and Full Scale IQ

GAIvsIQ Laboratory

A psychological-resources laboratory for reading General Ability Index against Full Scale IQ. We publish the calculator, the Wechsler-composite library, and a nine-task estimate when no official report is on hand.

What we publish

Official composites you already have, subtracted and read against the manuals — GAI vs IQ, GAI vs CPI, and the primary indexes. A long explanation of GAI vs FSIQ across WAIS-IV, WAIS-5, and WISC-V. A construct-aligned nine-task battery if you have no report. The method and the sources are public. Last reviewed 2026-09-23.

Also published

The same reading note — how to read a GAI versus FSIQ gap on a Wechsler report — is also on a few public records and open listings. The calculator stays here.

What we are not

Not the WAIS or WISC. Not Pearson. Not a clinic. Not a substitute for a psychologist. We do not sell a diagnosis, and we do not reprint Pearson conversion or base-rate tables.

Write to the laboratory

The public inbox is hello@gaivsiq.com. Questions about the calculator, the nine-task estimate, a page that should move after a manual revision, or an order or receipt can go there. We do not give clinical advice over email.

How pages are kept

Composite definitions are checked against the Wechsler manuals and the papers listed on the method page. If a sentence is not in those sources, it is labeled as practice language, not as a Pearson cutoff. When a manual or a scoring table is revised, these pages should move.

Read the method, the GAI vs FSIQ guide, or terms.
