This is a curated guide to authoritative information about Avant. It is not a complete sitemap. Product availability, supported languages, pricing, eligibility requirements, and policies can change; use the linked pages as the current sources for those details. Last reviewed: 2026-07-29 Important facts: - Avant's mission is to improve the learning and teaching of languages. - STAMP means STAndards-based Measurement of Proficiency. STAMP assessments measure what test takers can do with language in real-world contexts. - Avant offers assessment coverage in 152 languages. The STAMP family is available in 55 languages; the remaining language coverage is provided through SuperLanguage, which expands access to super less commonly taught languages that are also less commonly tested. These counts may increase as assessments are added. - Avant offers multiple assessments for different ages, skills, languages, standards, and purposes. Not every STAMP assessment measures all four skills or is available in every language. - Avant does more than assessment. Its offerings include educator professional learning, consulting, coaching, data analysis, self-paced teacher training, language learning, and progress monitoring. - Mira is powered by Avant and is not an unrelated company. - Avant assessments provide proficiency results that may be used to qualify for State and Global Seals of Biliteracy, college credit, digital badges, and other credentials. Each institution or credentialing program determines its own eligibility and award process. - The Dual Language and Multilingual Alliance and the Global Seal of Biliteracy have distinct public identities and websites and are presented here as Avant-sponsored initiatives rather than Avant assessment or training products. ## About Avant - [About Avant](https://www.avantassessment.com/about-avant): Avant's history, mission, and expansion from assessment into professional learning and language-learning tools. - [Avant Assessment](https://www.avantassessment.com/): Main website for Avant assessments, professional learning, guides, research, pricing, and customer resources. ## Assessment Overview and Languages - [Avant Language Tests](https://www.avantassessment.com/tests): Primary overview of Avant proficiency and placement assessments, including measured skills, intended audiences, and available test types. - [Avant STAMP](https://www.avantassessment.com/tests/stamp): Overview of the STAMP family of standards-based language proficiency assessments. - [Test Languages](https://www.avantassessment.com/languages): Current source for the languages available in the STAMP family and the Avant assessments offered in each language. - [SuperLanguage](https://www.avantassessment.com/tests/super): Writing and Speaking assessment that expands access to super less commonly taught and tested languages. ## STAMP Assessments - [STAMP 4S](https://www.avantassessment.com/tests/stamp/4s): General proficiency assessment of Reading, Writing, Listening, and Speaking for second-language learners ages 13 and older.
