IELTS Writing Task 1 Band Descriptors & Nine-Band Scale Notes

IELTS Nine-Band Scale Overview

  • The IELTS scale is divided into 99 whole bands (with possible half-band scores, e.g. 7.0,  7.5,  8.57.0,\;7.5,\;8.5) that describe a candidate’s overall competence in English.
  • Band descriptors (general definitions):
    • 9 – Expert user
    • Fully operational command of language
    • Appropriate, accurate, fluent; complete understanding
    • 8 – Very good user
    • Fully operational command with only occasional, unsystematic inaccuracies/inappropriacies
    • Misunderstandings possible only in unfamiliar situations
    • Handles complex, detailed argumentation well
    • 7 – Good user
    • Operational command, though occasional inaccuracies, inappropriacies, misunderstandings
    • Generally handles complex language well; understands detailed reasoning
    • 6 – Competent user
    • Generally effective command despite some inaccuracies/inappropriacies
    • Can use and understand fairly complex language, especially in familiar situations
    • 5 – Modest user
    • Partial command; copes with overall meaning in most situations, though many mistakes
    • Able to handle basic communication in own field
    • 4 – Limited user
    • Basic competence limited to familiar situations
    • Frequent problems in understanding/expression; unable to use complex language
    • 3 – Extremely limited user
    • Conveys/understands only general meaning in very familiar situations
    • Frequent breakdowns in communication
    • 2 – Intermittent user
    • No real communication except most basic info with isolated words or formulae
    • Great difficulty understanding spoken/written English
    • 1 – Non-user
    • Essentially no ability beyond a few isolated words
    • 0 – Did not attempt
    • No assessable information provided (absent, uses another language, or totally memorised answer)

Writing Task 1 – Band Descriptor Framework

  • Four equally-weighted criteria, each graded 0–90\text{–}9:
    1. Task Achievement (TA)
    2. Coherence & Cohesion (CC)
    3. Lexical Resource (LR)
    4. Grammatical Range & Accuracy (GRA)
  • A script must fully match the positive features at a level to be awarded that band.
  • WHITE (negative) statements in the official tables highlight weaknesses that limit the rating.

1 Task Achievement (TA)

Band 9
  • All task requirements fully and appropriately satisfied
  • Extremely rare lapses in content
Band 8
  • Covers all requirements appropriately, relevantly, sufficiently
  • Academic: Key features skilfully selected, clearly presented, highlighted, illustrated
  • GT: All bullet points clearly presented and appropriately illustrated/extended
  • Only occasional omissions/lapses
Band 7
  • Requirements covered; content relevant & accurate (few omissions/lapses)
  • Format appropriate
  • Academic:
    • Selected key features covered & clearly highlighted (could be more fully/appropriately illustrated or extended)
    • Clear overview; data categorised; main trends/differences identified
  • GT:
    • All bullets covered & clearly highlighted (could be more fully/appropriately illustrated or extended)
    • Clear purpose; tone consistent & appropriate (minimal lapses)
Band 6
  • Response focuses on task; appropriate format
  • Academic:
    • Selected key features covered & adequately highlighted
    • Relevant overview attempted
    • Information selected & supported using figures/data
  • GT:
    • All bullets covered & adequately highlighted
    • Purpose generally clear with minor tone inconsistency
  • Some irrelevant/inaccurate info in details or examples
  • Some details missing/excessive; further extension/illustration needed
Band 5
  • Generally addresses task; format may be inappropriate in places
  • Academic: Key features not adequately covered; recounting mainly mechanical; may lack supporting data
  • GT: All bullets presented but one or more not adequately covered; purpose may be unclear at times; tone variable/inappropriate
  • Tendency to focus on detail without the bigger picture
  • Inclusion of irrelevant/inaccurate material detracts from TA; limited detail when extending/illustrating points
Band 4
  • Attempt to address task
  • Academic: Few key features selected
  • GT: Not all bullets presented; purpose not clearly explained/confused; tone may be inappropriate; format may be wrong
  • Presented features may be irrelevant, repetitive, inaccurate, inappropriate
Band 3
  • Does not address task requirements (possible data/diagram/situation misunderstanding)
  • Presented features largely irrelevant
  • Limited info, used repetitively
Band 2
  • Content barely relates to task
Band 1
  • ≤20\le 20 words: Band 1
  • Content wholly unrelated; any copied rubric discounted
Band 0

  • Range of cohesive devices (incl. reference & substitution) used flexibly, though some inaccuracy or over/under-use
Band 6
  • Information/ideas generally arranged coherently; clear overall progression
  • Cohesive devices used to good effect, but cohesion within/between sentences may be faulty/mechanical (misuse, overuse, omission)
  • Reference/substitution may lack flexibility or clarity, causing repetition/errors
Band 5
  • Organisation evident but not wholly logical; may lack overall progression, yet an underlying coherence present
  • Ideas related but sentences not fluently linked
  • Limited/overuse of cohesive devices with inaccuracy
  • Writing repetitive owing to inadequate/inaccurate reference/substitution
Band 4
  • Information/ideas evident but not arranged coherently; no clear progression

  • Some basic cohesive devices used, often inaccurate/repetitive
  • Inaccurate/lacking substitution or referencing
Band 3
  • No apparent logical organisation

Band 5
  • Resource limited but minimally adequate

  • Mix of simple & complex sentences; limited flexibility
  • Complex structures less accurate than simple ones
  • Grammar/punctuation errors occur, rarely impeding communication
Band 5
  • Limited, repetitive range of structures
  • Complex sentences attempted but faulty; greatest accuracy in simple forms
  • Frequent grammatical errors causing some reader difficulty
  • Punctuation may be faulty
Band 4
  • Very limited range; subordinate clauses rare; simple sentences dominate
  • Some accurate structures, but frequent errors may impede meaning
  • Punctuation often faulty/inadequate
Band 3
  • Sentence forms attempted, but grammar/punctuation errors predominate (except memorised or copied phrases)
  • Meaning mostly blocked; length may be insufficient for evidence of control
Band 2
  • Little/no evidence of sentence forms (except memorised phrases)
Band 1
  • ≤20\le 20 words; no rateable language
Band 0
  • No attempt / non-English / memorised

Practical & Ethical Considerations

  • Memorisation: Any answer proven to be totally memorised = Band 0.
  • Copied rubric is discounted from the word count.
  • Assessors must match positive features and note limiting (white-text) features.
  • Script length
  • Half-bands are awarded in the overall score by averaging the four criteria, e.g. 7+6+6+64= 6.25→6.5\frac{7+6+6+6}{4}=\,6.25\rightarrow6.5 (rounded up to nearest 0.50.5).

Inter-criterion Connections & Strategy Tips

  • High TA often correlates with strong CC (clear overview/ logical organisation).
  • LR & GRA often interact: risk-taking with vocabulary/complex grammar can raise potential band but also increase error frequency—balance precision and accuracy.
  • Tone (particularly in General Training letters) affects both TA (purpose) and LR (appropriacy of lexis).
  • Excessive detail without overview (Academic) limits TA and CC.
  • Over-reliance on fixed phrases can lower LR and potentially mark script as memorised (ethics risk).

Revision Checklist for Candidates

  • Fulfil every bullet/key feature; provide clear overview/purpose.
  • Organise ideas into logical paragraphs; use varied cohesive devices.
  • Employ precise vocabulary; avoid repetition; check spelling/word formation.
  • Use a range of sentence structures; proof-read for grammar/punctuation errors.
  • Stay within the required word length (≥150150 words for Task 1) but avoid unnecessary padding.
  • Maintain appropriate formal/informal tone according to task type.
