Updated 1 November 2026

- [What does the Model Correctness Index mean?](https://ifcchecker.com/help/model-correctness-index/): The Model Correctness Index is the share of tested elements that pass, reduced by up to 20 percent when parts of the model are left untested.
- [What do the status words mean?](https://ifcchecker.com/help/status-words/): Every element has one status: Pass, Fail or Untested, or Approved once you accept an untested element for the session.
- [How is the Results page laid out?](https://ifcchecker.com/help/read-the-results/): Results has four parts, one under the other.
