Terms of Service
Effective November 6, 2026. These terms govern use of the MathVista website, eight-question Quick Math Check, optional full diagnostic, and family reports.
1. The service
MathVista is an educational service for Grades 3–8, operated in the United States. It offers an eight-question Quick Math Check with a preliminary Starter Snapshot; an adult may continue to an optional full adaptive diagnostic and report.
2. Parent or legal-guardian use
The current assessment setup is for adults evaluating the experience with invented answers. Do not submit a child’s responses through that flow. Its checkbox does not verify parental identity or obtain verifiable parental consent. The service’s Grades 3–8 content does not override this restriction. Schools and educators must not treat a parent checkbox or these terms as school authorization or a student-data agreement.
3. Educational information
MathVista reports are educational tools. Any on-track or needs-attention indicator describes the selected skills assessed in that run, not a validated national benchmark or a complete measure of grade-level attainment. They are not school grades, standardized test scores, percentiles, psychological or medical evaluations, special-education eligibility decisions, or guarantees of future performance. Consider the findings alongside classwork, teacher observations, and other appropriate information.
4. Assessment results
The diagnostic asks a selected set of questions and may follow different paths. A report describes evidence from that run only. A skill may remain uncertain when the assessment does not collect enough independent evidence.
5. Saved sessions and reports
Live assessment and report access is tied to the originating browser through an essential ownership cookie. An adult may download a portable PDF or request a one-time report email. Email delivery is sent to the address entered, so check it carefully. A private report link expires within 24 hours or sooner when the underlying assessment expires; anyone who has the link may open it while valid. Downloaded or emailed copies can be saved or forwarded, and the person sharing them is responsible for choosing recipients and protecting copies.
6. Acceptable use
Do not attempt to bypass access controls, interfere with the diagnostic, automate excessive requests, upload malicious material, scrape restricted content, or use the service in a way that harms another person or the service. During this adult-only evaluation, parents and educators may use reports created with invented answers to assess the service. Do not submit a child’s responses or rely on an evaluation report as a finding about a child.
7. Content and intellectual property
MathVista and its licensors retain their rights in original website content, software, illustrations, and report presentation to the extent protected by law. Third-party material remains subject to its own rights and licenses. This does not transfer rights in mathematical facts, public standards, or information you provide. A family may download, print, and share its own report for personal and educational use.
8. Availability and updates
MathVista may be changed, corrected, suspended, or discontinued. Question content and routing may be updated when quality reviews identify an improvement or error. Assessment version information may be retained with a run so its report can be traced to the content and engine that produced it.
9. Payment
The current diagnostic and reports are free. No payment is required to use the available features.
10. No guaranteed outcome
MathVista aims to provide a useful starting point, but no assessment can guarantee a child’s learning outcome, school placement, instructional response, or academic result. Use the report to support conversations with an educator; it should not be the sole basis for high-stakes decisions. Nothing in these terms excludes liability or restricts consumer or privacy rights that cannot lawfully be excluded or restricted.
11. Privacy
The Privacy & Data Notice explains the information processed, retention periods, and deletion controls. Accepting these terms is not consent to marketing, optional email delivery, or a data practice that requires a separate notice or consent.
12. Changes to these terms
Material changes will be reflected by a new effective date. Where the law requires notice or consent before a change, MathVista will provide it before introducing the changed practice. Continued use does not replace any consent required by law.
