(NFATC). It consists of descriptions of five levels of language proficiency, and is the standard grading scale for language proficiency in the Federal service.

ILR Level 1 - Elementary proficiency

This is the first and essential level of the scale, often called S-1 or Level 1. 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
The majority of individuals classified as S-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 the second level in the scale. This level is sometimes referred to as S-2 or level 2. 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 the third level in the scale. This level is sometimes referred to as S-3 or Level 3. S-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 a is the fourth level in the scale. This level is sometimes referred to as S-4 or level 4. A person at this level is described as follows:

able to use the language fluently and accurately on all levels 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 situations
makes only quite rare and unpatterned errors of pronunciation and grammar
can handle informal interpreting from and into the language.

ILR Level 5 - Native or bilingual proficiency

Native or bilingual proficiency is the fifth level in the scale. This level is sometimes referred to as S-5 or level 5. 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.
