Other Proficiency Scales
STANAG Scale – Used by the military in Europe, the STANAG 6001 (Standardization Agreement) is an international military standard created by the North Atlantic Treaty Organization (NATO) allowing comparisons of language ability in different countries who may cooperate in military operations. The scale consists of a set of descriptors with proficiency skills broken down into six levels from No Practical Proficiency through Excellent (Native/Bilingual).
ACTFL/LTI assessments provide valid, reliable ACTFL, ILR, or CEFR ratings, depending upon client requirements. Testers are trained and certified separately on each scale, avoiding the pitfalls inherent in attempts to build simple crosswalks equating proficiency across the scales.
