Terms & Conditions

These Terms & Conditions govern access to and use of US Academic Scores. By using the website, visitors agree to use its content, data tools and related features lawfully and in accordance with the conditions described on this page.

US Academic Scores provides education assessment data, charts, tables, comparisons and explanatory material relating to PISA, TIMSS, PIRLS, NAEP, ICILS and associated academic performance measures.

The website may be used for personal, educational, research and informational purposes, subject to these Terms & Conditions and any applicable law.

Use of the website does not create an advisory, professional, contractual or educational relationship between US Academic Scores and the visitor.

Visitors may read, reference and link to publicly available pages on US Academic Scores. Individual facts and statistics may be cited in accordance with applicable law and the rights associated with the underlying source data.

When a statistic originates from an external organization such as NCES, OECD, IEA or the Nation’s Report Card, the original source remains the authoritative source for that information and may have its own terms governing reuse.

Website presentation, original explanatory text, page structure, custom graphics, software components and other original material may be protected by copyright and other applicable intellectual property laws.

The website must not be used in a manner that interferes with its operation, compromises security, violates applicable law or harms other users.

Prohibited activity includes attempts to gain unauthorized access to website systems, introduce malicious code, bypass technical restrictions, disrupt service availability or use automated activity at a volume that materially impairs normal operation.

Content must not be presented in a way that falsely suggests endorsement, affiliation or official approval by US Academic Scores or by an assessment organization referenced on the site.

Assessment statistics are presented within the definitions and technical frameworks of the organizations that produced them. Scores from different assessments, populations, grades, subjects or cycles may not be directly comparable.

Visitors are responsible for considering relevant methodological notes, statistical uncertainty and source qualifications before relying on a comparison or derived conclusion.

Content on US Academic Scores is provided for informational purposes and does not constitute educational, legal, financial, policy or other professional advice.

Assessment results should not be used as the sole basis for decisions concerning an individual student, teacher, school, district, state or education system.

Visitors requiring an authoritative interpretation of an assessment methodology, dataset or official result should consult the organization responsible for that assessment.

Assessment data and technical documentation may be revised by their original publishers. Website content may also change as new assessment cycles, corrected datasets or additional source material become available.

No guarantee is made that every page, chart, table, external link or interactive feature will remain continuously available or completely free from error.

If information shown on US Academic Scores conflicts with the current official source, the official source should be treated as authoritative.

Interactive charts, sortable tables, search tools and downloadable data features are provided to make published information easier to explore. These tools do not change the meaning or statistical status of the underlying data.

Technical issues, browser settings, JavaScript restrictions, network failures or third-party service interruptions may temporarily affect interactive functionality.

Where an HTML data table accompanies a chart, the table should be used to confirm exact displayed values.

US Academic Scores links to external organizations, reports, databases and technical resources for reference and source verification.

External websites operate independently and may change their content, addresses, availability, policies or terms without notice. US Academic Scores does not control or assume responsibility for material hosted on independent external websites.

A link to an external website does not imply endorsement of every statement, product, service or policy available on that website.

Names such as PISA, TIMSS, PIRLS, NAEP, ICILS, OECD, NCES, IEA and the Nation’s Report Card may appear for identification, description and source attribution.

Ownership of third-party names, trademarks, logos and related intellectual property remains with the respective rights holders. Their appearance on the website does not imply sponsorship, affiliation or endorsement unless expressly stated by the rights holder.

Original website text, organization, design elements, custom code, visual presentation and other original material are protected to the extent provided by applicable intellectual property law.

Publicly available government data and third-party assessment materials retain the legal status and usage conditions established by their respective publishers. Inclusion of such information on US Academic Scores does not transfer ownership of the underlying source material.

Substantial reproduction of original website content, automated republication of complete pages or redistribution designed to substitute for the website may require permission unless permitted by applicable law.

Reasonable automated access by search engines and other legitimate indexing services may be permitted subject to technical controls made available through the website.

Automated requests must not place an excessive burden on website infrastructure, circumvent access controls, interfere with normal visitor access or be used for abusive scraping activity.

Technical measures may be used to limit or block automated activity that threatens security, availability or normal website operation.

Messages submitted through a contact form or email must not contain unlawful material, malicious code, harassment, impersonation or content intended to interfere with website operation.

Requests relating to corrections, copyright, privacy or other legal matters should contain enough information to identify the relevant page, material or issue.

The website may use third-party services for advertising, analytics, hosting, security or other technical functions. Those services may operate under separate terms and privacy policies.

Advertisements, when present, are separate from the education assessment content of the website. The appearance of an advertisement does not constitute endorsement of the advertiser, product or service.

To the extent permitted by applicable law, US Academic Scores is not liable for losses or damages arising solely from reliance on website content, temporary unavailability, technical errors, external websites or changes made by third-party data providers.

Visitors remain responsible for verifying information with authoritative sources when accuracy is material to a decision, publication, research project or professional use.

To the extent permitted by applicable law, a visitor may be responsible for claims, losses or expenses resulting from unlawful use of the website, violation of these Terms & Conditions or infringement of the rights of another person or organization.

Pages, datasets, features, navigation structures and technical functionality may be modified, replaced or discontinued as the website develops or as underlying assessment data changes.

Older URLs or data presentations may be redirected or replaced when a newer page provides the current version of substantially the same information.

These Terms & Conditions may be revised to reflect changes in website functionality, applicable requirements or operating practices. Continued use of the website after a revised version is published is subject to the version available at the time of use.

If any provision of these Terms & Conditions is found to be invalid or unenforceable under applicable law, the remaining provisions continue to apply to the extent legally permitted.
