STANAG 6001 Level Descriptors
A practical Academy summary of the NATO language proficiency framework across Listening, Speaking, Reading and Writing. Use the official NATO and BILC materials for the full descriptors.
How to read this page
01
STANAG 6001 describes proficiency separately in Listening, Speaking, Reading and Writing.
02
An SLP uses four positions in this order: L, S, R, W. For example, SLP 3232 means Listening 3, Speaking 2, Reading 3, Writing 2.
03
The six base proficiency levels are 0, 1, 2, 3, 4 and 5, from No Proficiency to Highly-Articulate Native.
04
A plus level may be used between Levels 0 and 4 when proficiency clearly exceeds a base level but does not fully meet the next base level.
STANAG 6001 is a proficiency framework, not one universal NATO exam
STANAG 6001 provides a common framework for describing and reporting language proficiency. Participating nations retain their own national testing systems, so test format, administration, timing and procedures can differ by country.
This page is a simplified Academy guide. For the authoritative framework, consult the BILC STANAG 6001 reference page and the official NATO language proficiency publication linked there.
