Evidence of Language Proficiency Required

For many languages, including English, specific assessments exist and provide a valid and reliable means of measuring students' language performance. The evidence needs to evaluate students' use of the language, not knowledge about the language. We recommend that schools help students maintain a portfolio of their language performance, such as the LinguaFolio®, tracking improvement and progress toward the level required for the Seal of Biliteracy. One element of such a portfolio is assessment measures that are outside the assessments for a specific course. We recommend that states may determine the process for assessing students to meet the requirements of the Seal of Biliteracy in cases where assessments of specific languages may not be available.


We recommend demonstrating proficiency in English by meeting language arts requirements for high school graduation or demonstrating proficiency on a validated test of proficiency for English learners. Assessments in English may include one or more of the following as determined by the state:

  • State assessments of English language arts as required for all learners
  • State assessments of English language development for English learners
  • Other assessments identified by the state as appropriate for demonstrating English proficiency equivalent to meeting high school graduation requirements.

Other Languages:

We recommend demonstrating proficiency in the language other than English by demonstrating proficiency on a validated test of proficiency as determined by the state. States will determine the assessments that are acceptable for purposes of demonstrating proficiency in a language other than English. Examples include:

  • Advanced Placement Exam
  • International Baccalaureate Exam
  • Oral Proficiency Interview, Reading Proficiency Test, or Writing Proficiency Test
  • Standards-based Measurement of Proficiency (STAMP4S)
  • ACTFL Assessment of Performance toward Proficiency in Languages (AAPPL)
  • Tribal language assessments
  • Signed Language Proficiency Interview (SLPI) for American Sign Language
  • ACTFL Latin Interpretive Reading Exam (ALIRA)
  • LAS Links Español | Data Recognition Corporation (DRC)
  • Other assessments correlated to the required minimum level of language proficiency.
