Clinician tools
Structured walkthroughs for the parts of intake where it’s easy to skip a step. Each one moves through history, impairment, rule-outs, differentials, collateral, and screening options, then gives you a worksheet summary of considerations to explore, rule-outs still open, and next steps. They never produce a diagnosis.
For licensed clinicians and supervised associates. These tools are not diagnostic instruments and are not a substitute for clinical judgment or formal assessment. They organize the questions; you make the clinical decisions, within your license and scope of practice, and with supervision if you are an associate. Diagnostic criteria live in the DSM-5-TR and ICD-11; check them directly. Nothing you enter is sent anywhere or saved, and refreshing the page clears it. Please don’t enter names or other identifying client information.

- Nothing leaves your browser. Answers stay on the page while it is open. There is no account, no saving, and nothing is sent anywhere. Refreshing or closing the page clears everything.
- Print or copy the summary. The last step builds a worksheet you can print or copy into your own notes. Keep identifying details out of it until it is in your records system.
- Considerations, not conclusions. The summary lists patterns to explore and questions still open. Diagnosis stays with you, using the DSM-5-TR or ICD-11 and your own clinical judgment.
- Supervised associates should use these alongside supervision, not instead of it.
- Instruments are named, not reproduced. Where a screening instrument is mentioned, the tool tells you where the official version lives and any licensing or training terms the publisher lists.
