How to read a GAI vs FSIQ gap on a Wechsler report

A free calculator that only subtracts official Wechsler scores.

Open the GAI vs IQ calculator

What this is

You already have a Wechsler report with official FSIQ, GAI, CPI, or index scores.

This page helps you read the GAI minus FSIQ gap. It does not give you a new IQ test.

What this is not

• Not a new IQ exam
• Not a clinical diagnosis
• Not a Pearson or WAIS official tool
• Not school, work, or visa documentation

Official scores only

Paste the numbers printed on the report.

Do not invent subtest totals. Do not treat an estimate as a replacement for a licensed examiner.

Why the gap matters

GAI leans on verbal and perceptual indexes.

FSIQ also includes working memory and processing speed.

A gap can be large even when both scores are official. The calculator shows the subtraction; it does not interpret eligibility.

Limits

A calculator cannot replace a psychologist.

Do not send this output to a school, employer, or visa office as proof.

If you need a formal interpretation, talk to the examiner who signed the report.
