The WAIS-IV A&NZ Language Adapted Edition is the industry standard test to measure adult intelligence.
Language adapted for Australia and New Zealand, the WAIS-IV gives you results you can trust and the most advanced measure of cognitive ability. The test was developed with these key goals:
- Efficient administration time
- Enhanced user friendliness
- Improved subtest and composite reliability
- Updated norms
The scoring and reporting software has been carefully designed and enhanced to improve ease of use and functionality.
In recognition of emerging demographic and clinical trends, the Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) was developed to provide you with the most advanced measure of cognitive ability and results you can trust. The WAIS-IV offers precision and simplicity in one comprehensive battery combined with the enhanced utility that results from the rigorous collection and stratification of normative data
that is the hallmark of Wechsler tradition.
It is this commitment to excellence that led us to focus on four issues to guide the WAIS-IV revision:
- Changing demographics
- Shifting clinical needs
- Emerging research
- Increasing caseload
Australia and New Zealand Language Adaptation
To maintain high levels of validity and reliability, and to ensure the most effective use in Australia and New Zealand, the WAIS-IV has been language adapted for our populations.
Test Structure
The WAIS-IV structure was modified to align with the widely popular WISC-IV and to reflect current theory regarding cognitive ability.
The new structure is also more reflective of current cognitive ability theory and divides scores into four specific domains. The core battery consists of ten total subtests that yield the FSIQ and four Index Scores. There are also five supplemental subtests that may be substituted for core subtests or administered for additional information.
WAIS-IV Update
We want to bring to your attention a change we have made to the WAIS-IV Technical and Interpretive Manual, Table C.2: Differences Between the FSIQ and the GAI Required for Statistical Significance. The formula previously used to calculate these values did not account for the subtests that are common to both composite scores. The attached table serves as the replacement for Table C.2. This change does not affect the calculation of an examinee's subtest or composite scores.

Tests in the WAIS-IV A&NZ harness the processing capacities of Q-interactive to provide new, more dynamic, cognitively demanding tasks that are unable to be delivered and scored with fidelity in a traditional paper format.
