Band	Description
9	Full flexibility and precise use are evident within the scope of the task. A wide range of vocabulary is used accurately and appropriately with very natural and sophisticated control of lexical features. Minor errors in spelling and word formation are extremely rare and have minimal impact on communication.
8	A wide resource is fluently and flexibly used to convey precise meanings within the scope of the task. There is a skillful use of uncommon and/or idiomatic items when appropriate, despite occasional inaccuracies in word choice and collocation. Occasional errors in spelling and/or word formation may occur, but have minimal impact on communication.
7	The resource is sufficient to allow some flexibility and precision. There is some ability to use less common and/or idiomatic items. An awareness of style and collocation is evident, though inappropriacies occur. There are only a few errors in spelling and/or word formation, and they do not detract from overall clarity.
6	The resource is generally adequate and appropriate for the task. The meaning is generally clear in spite of a rather restricted range or a lack of precision in word choice. If the writer is a risk-taker, there will be a wider range of vocabulary used but higher degrees of inaccuracy or inappropriacy. There are some errors in spelling and/or word formation, but these do not impede communication.
5	The resource is limited but minimally adequate for the task. Simple vocabulary may be used accurately but the range does not permit much variation in expression. There may be frequent lapses in the appropriacy of word choice, and a lack of flexibility is apparent in frequent simplifications and/or repetitions. Errors in spelling and/or word formation may be noticeable and may cause some difficulty for the reader.
4	The resource is limited and inadequate for or unrelated to the task. Vocabulary is basic and may be used repetitively. There may be inappropriate use of lexical chunks (e.g. memorized phrases, formulaic language and/or language from the input material). Inappropriate word choice and/or errors in word formation and/or in spelling may impede meaning.
3	The resource is inadequate (which may be due to the response being significantly underlength). Possible over-dependence on input material or memorized language. Control of word choice and/or spelling is very limited, and errors predominate. These errors may severely impede meaning.
2	The resource is extremely limited with few recognisable strings, apart from memorized phrases. There is no apparent control of word formation and/or spelling.
1	No resource is apparent, except for a few isolated words.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://api-docs.speechace.com/guides-on-common-topics/interpreting-writing-scores/vocabulary-bands.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
