Research Consent

De-identification, statistical analysis, and withdrawal

Research consent is optional and declining does not prevent testing. When consent is granted, responses, scores, response times, assigned Forms, age band, language, education, testing environment, and device context may be analyzed separately from direct identifiers.

Consent can be withdrawn from the account page. After withdrawal, the affected sessions are excluded from future aggregation and any norm containing those sessions is invalidated pending recomputation. Legally required records and aggregates that have already been irreversibly de-identified are handled under the Privacy Policy.
