IELTSスピーキング試験では、以下の採点基準（Band Descriptors）したがって、流暢さと一貫性（Fluency and Coherence）、語彙力（Lexical Resource）、文法（Grammatical Range and Accuracy）、発音（Pronunciation）の4項目で評価されます。それぞれ、Band 9からBand 0までの整数値でスコアリングされ、最終的なスピーキングのスコアは、平均値に最も近い0.5単位に切り下げられます。

例えば、Fluency and Coherence: 6、Lexical Resource: 6、Grammatical Range and Accuracy: 7、Pronunciation: 6の場合、平均値は6.25で、最も近い0.5単位に切り下げられるため、最終的なスピーキングのスコアは6.0となります。

Band	Fluency and Coherence	Lexical Resource	Grammatical Range and Accuracy	Pronunciation
9	- speaks fluently with only rare repetition or self-correction; any hesitation is content-related rather than to find words or grammar - speaks coherently with fully appropriate cohesive features - develops topics fully and appropriately	- uses vocabulary with full flexibility and precision in all topics - uses idiomatic language naturally and accurately	- uses a full range of structures naturally and appropriately - produces consistently accurate structures apart from 'slips' characteristic of native speaker speech	- uses a full range of pronunciation features with precision and subtlety - sustains flexible use of features throughout - is effortless to understand
8	- speaks fluently with only occasional repetition or self-correction; hesitation is usually content-related and only rarely to search for language - develops topics coherently and appropriately	- uses a wide vocabulary resource readily and flexibly to convey precise meaning - uses less common and idiomatic vocabulary skilfully, with occasional inaccuracies - uses paraphrase effectively as required	- uses a wide range of structures flexibly - produces a majority of error-free sentences with only very occasional inappropriacies or basic/non-systematic errors	- uses a wide range of pronunciation features - sustains flexible use of features, with only occasional lapses - is easy to understand throughout; L1 accent has minimal effect on intelligibility
7	- speaks at length without noticeable effort or loss of coherence - may demonstrate language-related hesitation at times, or some repetition and/or self-correction - uses a range of connectives and discourse markers with some flexibility	- uses vocabulary resource flexibly to discuss a variety of topics - uses some less common and idiomatic vocabulary and shows some awareness of style and collocation, with some inappropriate choices - uses paraphrase effectively	- uses a range of complex structures with some flexibility - frequently produces error-free sentences, though some grammatical mistakes persist	- shows all the positive features of Band 6 and some, but not all, of the positive features of Band 8
6	- is willing to speak at length, though may lose coherence at times due to occasional repetition, self-correction or hesitation - uses a range of connectives and discourse markers but not always appropriately	- has a wide enough vocabulary to discuss topics at length and make meaning clear in spite of inappropriacies - generally paraphrases successfully	- uses a mix of simple and complex structures, but with limited flexibility - may make frequent mistakes with complex structures, though these rarely cause comprehension problems	- uses a range of pronunciation features with mixed control - shows some effective use of features but this is not sustained - can generally be understood throughout, though mispronunciation of individual words or sounds reduces clarity at times
5	- usually maintains flow of speech but uses repetition, self-correction and/or slow speech to keep going - may over-use certain connectives and discourse markers - produces simple speech fluently, but more complex communication causes fluency problems	- manages to talk about familiar and unfamiliar topics but uses vocabulary with limited flexibility - attempts to use paraphrase but with mixed success	- produces basic sentence forms with reasonable accuracy - uses a limited range of more complex structures, but these usually contain errors and may cause some comprehension problems	- shows all the positive features of Band 4 and some, but not all, of the positive features of Band 6
4	- cannot respond without noticeable pauses and may speak slowly, with frequent repetition and self-correction - links basic sentences but with repetitious use of simple connectives and some breakdowns in coherence	- is able to talk about familiar topics but can only convey basic meaning on unfamiliar topics and makes frequent errors in word choice - rarely attempts paraphrase	- produces basic sentence forms and some correct simple sentences but subordinate structures are rare - errors are frequent and may lead to misunderstanding	- uses a limited range of pronunciation features - attempts to control features but lapses are frequent - mispronunciations are frequent and cause some difficulty for the listener
3	- speaks with long pauses - has limited ability to link simple sentences - gives only simple responses and is frequently unable to convey basic message	- uses simple vocabulary to convey personal information - has insufficient vocabulary for less familiar topics	- attempts basic sentence forms but with limited success, or relies on apparently memorised utterances - makes numerous errors except in memorised expressions	- shows some of the features of Band 2 and some, but not all, of the positive features of Band 4
2	- pauses lengthily before most words - little communication possible	- only produces isolated words or memorised utterances	- cannot produce basic sentence forms	- speech is often unintelligible
1	- no communication possible - no rateable language
0	- does not attend
