The IELTS Speaking test is assessed based on four key criteria that collectively determine the final band score. Understanding these assessment categories in their original English formulation helps candidates better comprehend examiner expectations and refine their preparation strategies accordingly. Each criterion carries equal weight in the overall evaluation.
Fluency and Coherence
This criterion evaluates the smoothness and logical flow of speech. Examiners assess the ability to speak at length without excessive hesitation or self-correction. Coherence refers to how logically ideas are connected and sequenced. High-scoring responses demonstrate natural linking between sentences using appropriate connectors. Speech rate should be consistent, neither too slow nor unnaturally fast. Avoid long pauses and frequent repetition of phrases.
Lexical Resource
This measures vocabulary range and precision. Examiners look for varied word choices beyond basic vocabulary, including idiomatic expressions when appropriate. Words must be used accurately in context with correct collocations. Higher bands require effective paraphrasing when lacking exact vocabulary. Misused words or inappropriate register will lower scores. The focus isn't on complex words but on using vocabulary flexibly to discuss various topics.
Grammatical Range and Accuracy
This assesses sentence structure variety and grammatical correctness. Higher scores demand a mix of simple and complex structures used appropriately. Errors are expected but shouldn't impede communication. Consistent basic mistakes limit scores even with complex structures. Tense consistency and correct word formation are particularly scrutinized. Examiners notice if grammatical errors distort meaning.
Pronunciation
This evaluates speech clarity and comprehensibility. Examiners consider individual sounds, word stress, sentence rhythm and intonation patterns. Accents are acceptable if they don't hinder understanding. Key features include correct word and sentence stress placement, and appropriate intonation to convey meaning. Don't exaggerate pronunciation; aim for natural delivery. Consistent mispronunciation of common words affects scoring.
The IELTS Speaking band descriptors provide detailed performance characteristics for each score level across these four criteria. Official practice materials include sample responses at different band levels for comparison. Regular self-recording and analysis against these standards helps identify improvement areas. Remember, examiners assess your current ability, not your potential, so demonstrate your best English during the test. Consistent practice with these criteria in mind leads to gradual but definite progress in speaking proficiency.
