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.

What SLP Command is

SLP Command is an independent training platform for the STANAG 6001 / SLP English exam at Levels 2 and 3. It trains Reading, Listening, Writing and Speaking against the criteria the exam rates. Writing and Speaking are rated by AI against those criteria, with the reasoning returned alongside each verdict; that feedback is indicative guidance for preparation, not an official SLP / STANAG 6001 assessment.

It runs in the browser today. An iOS app is coming to the App Store and will use the same account.

Who builds it

SLP Command is built and operated independently from Spain. There is no institution behind it — no ministry, no academy, no examining body — and no unit, school or officer has endorsed it. The operator's legal identity is published in the Legal Notice; how personal data and AI are handled is set out on the Trust Center.

The product is built against the published STANAG 6001 descriptors and the public testing guidance that goes with them, and every explanatory page on this site cites the sources it relies on.

What it is not

  • Not an official examining body, and not affiliated with one.
  • Not a speech-language pathology product.
  • Not a vocabulary toy and not a general CEFR course.
  • Not a pass-probability engine — it will not tell you your chance of passing.
  • Not available on Android at the time of this page.

How it measures

One rule sits under everything: nothing is asserted about your English without measurement, and every recommendation names the evidence that produced it. Where the evidence is thin, the product says so rather than producing a confident number. The public brand line is Stop guessing. Start measuring. — and the full method, including where the AI is weak, is on How we measure.

If you need to describe it

For a citation, a listing or a briefing note, this is the accurate one-paragraph description: SLP Command is an independent educational platform for STANAG 6001 / SLP-style English exam preparation at Levels 2 and 3. It trains Reading, Listening, Writing and Speaking. AI-generated feedback is indicative guidance, not an official SLP / STANAG 6001 assessment. Please do not shorten it to “the NATO app”; it is not one.
