FREQUENT QUESTIONS
Questions parents ask
Is this a standardized assessment?
No. This is a short practice check using a demonstration question set. It cannot identify a learning disability, provide a grade-equivalent score, or establish complete mastery.
Do you save my child's answers?
In this release, no account exists and the browser does not send or store responses on a server. Individual answers exist only in the open page until you leave or refresh. An adult can opt to save a brief aggregate practice plan on this device for 14 days; it is never sent to our server. Hosting access logs may be handled by Cloudflare.
Is the content reviewed by a teacher?
Not yet. These are original demonstration questions and need independent curriculum and accessibility review before being marketed as a validated educational assessment.
