SLP1 (standardized language proficiency)

SLP1 stands for standardized language proficiency. This is the expansion given in NATO's glossary of acronyms and abbreviations, and the entry cross-references STANAG 6001, the NATO standard associated with language proficiency levels and standardized language profiles.

The term comes from NATO terminology and language-standardization usage. It is distinct from SLP, which NATO uses for a standardized language profile. In NATO procurement documents, a person's language level is usually written as a four-digit profile, such as SLP 3333. Bid teams who see these profiles in a solicitation need to know what the digits cover and how they are used.

How NATO's glossary defines SLP1

The NATO abbreviations glossary (AAP-15) expands SLP1 as "standardized language proficiency" and points the reader to STANAG 6001. The glossary is published through the NATO archives, and you can read the entry in the AAP-15 glossary of NATO acronyms and abbreviations.

NATO also maintains NATOTerm, its official terminology database. It is maintained by the NATO Terminology Office within the NATO Standardization Office. It is the place to check NATO's own wording for a term.

STANAG 6001 and the four-digit SLP profile

STANAG 6001 is the NATO standard for describing language proficiency in levels. NATO procurement material applies it by giving each person a four-digit profile. The digits cover four skills: listening, speaking, reading and writing. A profile of SLP 3333 therefore sets a level of 3 in each of the four skills. The NATO Allied Command Transformation document IFIB-ACT-SACT-25-01 Part E, amendment 2 describes SLP 3333 under STANAG 6001 in exactly these terms.

The digits identify proficiency levels across the skills. They are not part of the abbreviation SLP1. NATO procurement material has used other profiles as well, including SLP 4444, as shown in IFIB-ACT-SACT-23-01 amendment 2.

SLP1 compared with SLP

The two abbreviations should not be treated as interchangeable. SLP1 is glossed as standardized language proficiency. SLP is glossed as standardized language profile. When a solicitation writes a four-digit figure after SLP, it is stating a profile made up of one level for each language skill.

Where a solicitation uses either abbreviation, check how the document itself defines it and which skills and levels it requires. The NATO archives also hold an early draft of the standard, listed as the first draft of the STANAG 6001 language proficiency levels.

What SLP requirements mean for a supplier bidding on Canadian public contracts

NATO procurement documents use SLP 3333 as a required or equivalent English-proficiency level for proposed personnel. One example is IFIB-ACT-SACT-23-01 Part E, amendment 1. A supplier responding to a NATO-issued bid should expect to show that named staff meet the stated profile in all four skills.

For Canadian solicitations, rely on the language requirement wording and definitions in the solicitation you are bidding on. Each buyer sets its own terms. Before submitting, confirm the following:

• Which abbreviation the document uses, SLP1 or SLP.
• Which skills it covers and what level it sets for each.
• Which proposed personnel the requirement applies to.
• What evidence of proficiency the document asks you to provide.
