ILR (Interagency Language Roundtable)

The Interagency Language Roundtable (ILR) is a U.S. government organization that provides guidelines and standards for language proficiency assessment and training. The ILR scale, also known as the ILR proficiency scale, is widely used to measure language proficiency levels in federal agencies. The scale ranges from Level 0 (No Proficiency) to Level 5 (Native or Bilingual Proficiency). In language education, the ILR standards help guide curriculum development, assessment, and training programs to ensure that learners achieve the desired levels of proficiency for their professional or personal needs.
