The chart below shows the sleep patterns of people in five different occupations according to a Canadian study.
Sample Response
The diagram outlines the sleep patternspattern of students, truck drivers, mothers, business executives and doctors overin a typical day. Generally speaking, students and business executives have a steady sleep pattern, whilesteady sleep pattern while others sleep in a scattered fashion. The chart showsIt is explicitly observed that students usually sleep for eight hourssleep 8 hours a day, from 11.00 pm to 7.00 am, without any interruption and their sleep duration is longer than that of peopletheir duration of rest is higher than people from other professions. Business executives have a continuous sleepnap schedule but they sleep only 6 hours, from 11 p.m. to 5 a.m.from 11 pm to 5 pm. Truck drivers seem tolike have the most sporadic sleep schedule and they sleep for six hours a daythey sleep 6 hours a day in separate periodsin a scattered way in the early morning and the eveningevening time. A similar sleep patternrest agenda could be observed for full-time mothers who sleep for eight hourstake rest 8 hours a day but at three different times of the day. They are usually awake at midnightmid-night as do the truck drivers. Finally, doctors sleep only 5 hours a day, the shortest duration among the five groupsthe least among the given categories, and they sleep from late at night until early morninglate night till early morning with the exception of 3–4 a.m.exception of 3-4 in the morning when they remain awake.
Why this response received Band 6.0
The response's strongest feature is its comprehensive occupation-by-occupation coverage and a useful overview contrasting continuous with scattered sleep patterns. Its main limitation is accuracy: students are presented as sleeping longer than every other group despite mothers also receiving eight hours, and the executive schedule ends at 5 pm rather than 5 am. The priority is to verify every duration and time label against the chart before describing comparisons.
IELTS Writing Criteria Scores
Task Achievement
The response gives a clear overview and addresses all five occupations, but a few significant timing and comparative claims are inaccurate.
Check each sleeping interval and total carefully, especially the executive end time and the equal eight-hour totals for students and mothers.
Coherence and Cohesion
The report progresses logically from the overview through each occupation, although presenting everything in one paragraph reduces structural clarity.
Separate the overview from two grouped detail paragraphs, contrasting regular sleepers with those whose sleep is interrupted.
Lexical Resource
Vocabulary shows useful range for describing regularity and duration, but several collocations are unnatural, including "rest agenda" and "take rest."
Prefer precise chart terms such as "sleep schedule," "sleep for eight hours," and "interrupted sleep periods."
Grammatical Range and Accuracy
A range of sentence structures communicates the comparisons clearly overall, but recurring construction and comparison errors reduce control.
Correct patterns such as "seem to have" and compare durations with those of other groups rather than with the people themselves.
