Open item-level analytics from the same bank that powers the live assessments.
This page publishes aggregate statistics on assessment items: which questions discriminate traits best, how traits correlate, test quality summaries, and IRT calibration views. Nothing here is behind a login; it is the same transparency we describe in our philosophy.
Use the tabs to compare best and worst items per trait, inspect test stats across assessments, or review accuracy and IRT curves. Select an assessment to scope the tables to that instrument, or compare two assessments side by side.
We publish this so researchers, typologists, and curious test-takers can see how scores are built instead of trusting a black box. The item bank is living data: weak items are removed, strong items are weighted more heavily, and the whole system improves with every response.
If you are conducting research, the statistics on this page are published for open review. You do not need to ask permission to read what you see here.
Accuracy rate for test-takers who reported their type before taking the assessment. Compare match rates by declared type, test length, and version.
