ILR scale - Wikipedia
en.wikipedia.org › wiki › ILR_scaleThe scale grades people's language proficiency on a scale of 0–5. The designation 0+, 1+, 2+, 3+, or 4+ is assigned when proficiency substantially exceeds one skill level but does not fully meet the criteria for the next level. Thus the scale totals 11 possible grades. Grades may be assigned separately for different skills such as reading, speaking, listening, writing, translation, audio translation, interpretation, and intercultural communication.
