MARKING AND ASSESSMENT

EACH TASK IS ASSESSED INDEPENDENTLY. THE ASSESSMENT OF TASK 2 CARRIES MORE WEIGHT IN MARKING THAN TASK 1.

Responses are assessed by certificated IELTS examiners. All IELTS examiners hold relevant teaching qualifications and are recruited as examiners by the test centers and approved by the British Council or IDP: IELTS Australia.

Scores are reported in whole and half bands. Detailed performance descriptors have been developed which describe written performance at the nine IELTS bands. These are available on the How IELTS is scored page. They apply to both IELTS Academic and IELTS General Training versions and are based on the following criteria.

Task 1 responses are assessed on:

• Task achievement
• Coherence and cohesion
• Lexical resource
• Grammatical range and accuracy.

Task 2 responses are assessed on:

• Task response
• Coherence and cohesion
• Lexical resource
• Grammatical range and accuracy.

PERFORMANCE DESCRIPTORS

Task 1

Task achievement
This assesses how appropriately, accurately and relevantly the response fulfills the requirements set out in the task, using the minimum of 150 words. Academic Writing Task 1 is a writing task, which has a defined input and a largely predictable output. It is basically an information-transfer task that relates narrowly to the factual content of an input diagram and not to speculative explanations that lie outside the given data.

Coherence and cohesion
This is concerns overall clarity and fluency: how the response organises and links information, ideas and language. Coherence refers to the linking of ideas through logical sequencing. Cohesion refers to the varied and appropriate use of cohesive devices (for example, logical connectors, pronouns and conjunctions) to assist in making the conceptual and referential relationships between and within sentences clear.

Lexical resource
This refers to the range of vocabulary used and its accuracy and appropriacy in terms of the specific task.

Grammatical range and accuracy
This refers to the range and accurate use of grammar as manifested in their sentence writing.

Task 2

Task response 
In both IELTS Academic and IELTS General Training versions, Task 2 requires test takers to formulate and develop a position in relation to a given prompt in the form of a question or statement. Ideas should be supported by evidence, and examples may be drawn from the test takers’ own experience. Responses must be at least 250 words in length. Scripts under the required minimum word limit will be penalised.

Coherence and cohesion
This assesses the overall clarity and fluency of the message: how the response organises and links information, ideas and language. Coherence refers to the linking of ideas through logical sequencing. Cohesion refers to the varied and appropriate use of cohesive devices (for example, logical connectors, pronouns and conjunctions) to assist in making the conceptual and referential relationships between and within sentences clear.

Lexical resource 
This criterion refers to the range of vocabulary used and its accuracy and appropriacy in terms of the specific task.

Grammatical range and accuracy
This assesses the range and accurate use of grammar, as manifested in their test takers’ writing at sentence level.
