The Interagency Language Roundtable scale is a set of descriptions of abilities to communicate in a language. It is the standard grading scale for language proficiency in the Federal service. It was originally developed by the Interagency Language Roundtable (ILR), which included representation by United States Foreign Service Institute, the predecessor of the National Foreign Affairs Training Center (NFATC). It grades people's language proficiency on a scale of 0-5. The designation 0+, 1+, 2+, 3+, or 4+ is assigned when proficiency substantially exceeds one skill level and does not fully meet the criteria for the next level. This totals 11 possible grades. Grades may be assigned separately for different skills such as reading, speaking, listening, writing, translation, audio translation, interpretation, and intercultural communication. For some of these skills, the level may be seen abbreviated, for example S-1 for Speaking Level 1.
- 1 ILR Level 0 – No proficiency
- 2 ILR Level 1 – Elementary proficiency
- 3 ILR Level 2 – Limited working proficiency
- 4 ILR Level 3 – Professional working proficiency
- 5 ILR Level 4 – Full professional proficiency
- 6 ILR Level 5 – Native or bilingual proficiency
- 7 Equivalence with the European language proficiency scale CEFR

ILR Level 0 – No proficiency
The baseline level of the scale is no proficiency, rated 0. The following describes the traits of an ILR Level 0 individual:
- oral production limited to occasional, isolated words
- may be able to ask questions or make statements with reasonable accuracy only with memorized utterances or formulae
- unable to read connected prose but may be able to read numbers, isolated words and phrases, personal and place names, street signs, office and shop designations
- understanding limited to occasional isolated words or memorized utterances in areas of immediate needs.
- may be able to produce symbols in an alphabetic or syllabic writing system or 50 of the most common characters
ILR Level 1 – Elementary proficiency
Elementary proficiency is rated 1 on the scale. The following describes the traits of an ILR Level 1 individual:
- can fulfill travelling needs and conduct themselves in a polite manner
- able to use questions and answers for simple topics within a limited level of experience
- able to understand basic questions and speech, which allows for guides, such as slower speech or repetition, to aid understanding
- has only a vocabulary large enough to communicate the most basic of needs; also makes frequent punctuation and grammatical mistakes in writing of the language
- speech is normally very laborious.
- The majority of individuals classified as Level 1 are able to perform most basic functions using the language. This includes buying goods, reading the time, ordering simple meals and asking for minimal directions.
ILR Level 2 – Limited working proficiency
Limited working proficiency is rated 2 on the scale. A person at this level is described as follows:
- able to satisfy routine social demands and limited work requirements
- can handle with confidence most basic social situations including introductions and casual conversations about current events, work, family, and autobiographical information
- can handle limited work requirements, needing help in handling any complications or difficulties; can get the gist of most conversations on non-technical subjects (i.e. topics which require no specialized knowledge), and has a speaking vocabulary sufficient to respond simply with some circumlocutions
- has an accent which, though often quite faulty, is intelligible
- can usually handle elementary constructions quite accurately but does not have thorough or confident control of the grammar.
ILR Level 3 – Professional working proficiency
Professional working proficiency is rated 3 on the scale. Level 3 is what is usually used to measure how many people in the world know a given language. A person at this level is described as follows:
- able to speak the language with sufficient structural accuracy and vocabulary to participate effectively in most conversations on practical, social, and professional topics
- can discuss particular interests and special fields of competence with reasonable ease
- has comprehension which is quite complete for a normal rate of speech
- has a general vocabulary which is broad enough that he or she rarely has to grope for a word
- has an accent which may be obviously foreign; has a good control of grammar; and whose errors virtually never interfere with understanding and rarely disturb the native speaker.
ILR Level 4 – Full professional proficiency
Full professional proficiency is rated 4 on the scale. A person at this level is described as follows:
- able to use the language fluently and accurately on all levels and as normally pertinent to professional needs.
- can understand and participate in any conversations within the range of own personal and professional experience with a high degree of fluency and precision of vocabulary
- would rarely be taken for a native speaker, but can respond appropriately even in unfamiliar grounds or situations
- makes only quite rare and minute errors of pronunciation and grammar
- can handle informal interpreting of the language.
ILR Level 5 – Native or bilingual proficiency
Native or bilingual proficiency is rated 5 on the scale. A person at this level is described as follows:
- has a speaking proficiency equivalent to that of an educated native speaker
- has complete fluency in the language, such that speech on all levels is fully accepted by educated native speakers in all of its features, including breadth of vocabulary and idiom, colloquialisms, and pertinent cultural references.
