Terminology

SLP means Standardized Language Profile — not speech therapy

Updated 2026-08-18 · Independent educational resource

The four-digit code

Independent resource. SLP Command is not affiliated with NATO, BILC, any Ministry of Defence, or any official examining body. National tests implement STANAG 6001 descriptors differently. Always confirm administration details with the authority that runs your sitting.

A Standardized Language Profile is written as four digits, in a fixed order:

People say “I have a 3” when they mean 3333. That shorthand hides the digit that is actually blocking a posting. Read the profile, not the story you tell about it.

Why search results are confusing

On the open web, SLP is dominated by speech-language pathology. STANAG without the number 6001 is dominated by rifle magazines. If you search either word alone you will not find exam preparation.

Useful queries name the standard and the job: STANAG 6001, SLP 3333, examen SLP militar, SLP 2222.

SLP 2222 and SLP 3333

SLP 2 / 2222 is the functional profile most forces treat as the working minimum for many international jobs. SLP 3 / 3333 is the professional profile: implication, hypothesis, argument, and unexpected questions.

The jump is not “more words”. It is a different kind of performance. Training a Level 2 memo until it is polished will not produce a Level 3 report.

Questions

Is SLP the same as speech-language pathology?

No. Outside defence, SLP almost always means speech-language pathology. In STANAG 6001 it means Standardized Language Profile. Always pair the letters with STANAG, military, or the four-digit code.

What order are the four digits?

Listening, Speaking, Reading, Writing. An SLP of 3232 is Level 3 listening, Level 2 speaking, Level 3 reading, Level 2 writing.

Can I average the four digits?

No. STANAG levels are not averages. A 3 in reading does not lift a 2 in writing. The profile reports each skill separately because postings often require a minimum on a specific digit.
