Run by their authors
Assessments published and maintained by practicing coaches and trainers — separate from the editorial clusters above.
Theory Portals are author pages — not editorially reviewed by AssessWiki. Claims and content are the author's own. How this works
{{ fact.text }}
{{ fact.linkText }}Every entry follows the same structure: what it measures, who it is for, what evidence supports it, what it cannot tell you, and what to do next. Not marketing numbers — promises you can check on any page:
Every entry states its limits
A fixed “What it cannot tell you” section on all 51 entries — see it on the Big Five page →
Sources you can follow
Every entry’s “Evidence and sources” section links the published research behind it — see the evidence →
Free, with no sign-up
No account, no email gate, no paywall — start any assessment directly.
15 published frameworks, referenced
Entries are filed under the researchers behind the theory — referenced, not affiliated. Meet them →
AssessWiki stays free and editorially independent. Theory Portals are author-run pages, clearly labeled and never mixed into our editorial rankings. How we stay free
