The ICA changelog
The current instrument is ICA 1.1. Every results export from the test is stamped with the version that produced it, so any result can be traced to the exact instrument.
Versions
| Version | Status | Notes |
|---|---|---|
| ICA 1.1 | Current | The version shown in every results export. This public changelog starts on 3 November 2026. |
What gets logged
- Any change to the wording of an item or response
- Any change to how answers are scored
- Any change to profile names, descriptions or the Orientation Strength Index bands
- Each entry gives the date, what changed and why
Why it matters
Practitioners and institutions need to know which version produced a result. Institutions on the Institutional License are told before a new version replaces the one they use.
Questions
Will old results still make sense after a change?
Each result records its version. If a change affects how a result should be read, the entry here says so.
