Direct answer

Examiners score Task 1 on four criteria. Task Achievement (TA), Coherence & Cohesion, Lexical Resource, and GRA, with TA driven by overview, accurate data selection, and format fit. Academic Task 1 needs a clear overview of main trends or stages; General Training letters need correct tone, purpose, and bullet coverage. CC rewards logical grouping of data; LR and GRA follow the same bands as Task 2 but with less argument depth required.

Task Achievement on charts and graphs

Examiners scan for overview first, then body paragraphs that support it. See comparison language traps and category overlap trap.

Overview Main trend or stage in one or two sentences

Selection Key figures compared, not every label copied

Accuracy No invented data or wrong units

Four criteria at a glance

Criterion	Examiner focus
TA	Overview + relevant data + format
CC	Logical paragraphing and linking
LR	Topic vocabulary for trends and comparison
GRA	Range and accuracy in descriptions

GT letters vs Academic reports

GT Task 1 TA includes greeting, purpose, bullet points, and closing tone. Academic TA is almost always report format with overview, see Academic vs General evaluation.

TA bands examiners distinguish

Band 6 Task 1

Overview present but mechanical; some data missing or inaccurate.

Band 7+ Task 1

Clear overview plus logical data grouping with few accuracy slips.

Select and compare key data, do not list every number.
GT letters are TA-heavy on tone and bullet coverage.
