ILR Scale

Developed by the Federal Government’s Inter-Agency Language Roundtable from basic descriptions used by the Foreign Service Institute, the ILR scale is the way in which the US Federal Government defines and refers to language ability. With 6 levels, ranging from 0 (No Practical Proficiency) through 5 (Native or Bilingual Proficiency), with ‘plus’ levels at each stage, the scale covers a wide range of abilities.
