IELTS Writing Task 1 question
The charts below show the changes in ownership of electrical appliances and amount of time spent doing housework in households in one country between 1920 and 2019.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Percentage of households with electrical appliances (1920-2019)
Student answer (Band 7.5)
Overall, a clear inverse relationship is evident between appliance ownership and the time spent on chores. As the percentage of households equipped with modern electrical devices surged to near-ubiquity, the total number of hours allocated to weekly housework dramatically declined over the 99-year period.In 1920, the washing machine was the most prevalent appliance, possessed by 40% of households, while vacuum cleaners were owned by 30%. In contrast, refrigerators were practically non-existent at just above 0%. However, refrigerator adoption experienced an exceptionally rapid growth, overtaking the other two appliances by 1940 and hitting 100% saturation by 1980, where it remained stable. Vacuum cleaner ownership also increased steadily, reaching full adoption (100%) by 2000. Conversely, the popularity of washing machines grew more gradually, fluctuating slightly around 1980 before finishing the period at approximately 75% in 2019.The widespread integration of these devices directly impacted household labor. In 1920, families spent an average of 50 hours per week on housework like washing clothes, preparing meals, and cleaning. This figure fell sharply over the next four decades, dropping to 20 hours in 1960. Following this period, the rate of decline slowed down but continued to decrease gradually, ultimately leveling off at just over 10 hours per week by 2019

Task Achievement / Task Response — Band 7.5
The student provides a highly accurate and well-developed response that effectively covers all parts of the task. An insightful overview is presented at the beginning, highlighting the clear inverse relationship between appliance ownership and time spent on housework. Key features of the line graphs, such as the initial 1920 figures, the rapid growth of refrigerators to 100% saturation, and the corresponding sharp drop in weekly chores from 50 to 11 hours, are accurately reported and supported with precise data points. Comparisons between appliances and across time periods are seamlessly integrated. The data is handled with precision, fulfilling all requirements of the Band 8 descriptor for this criterion.
Coherence and Cohesion — Band 7.5
The response is logically organized with a clear overall progression. The essay begins with a strong introductory overview, transitions into appliance ownership trends in the second paragraph, and concludes by analyzing the time spent on housework in the final paragraph. Cohesive devices such as 'In contrast', 'However', 'Conversely', and 'Following this period' are used effectively to guide the reader through the data. Paragraphing is logical and appropriate, ensuring that each distinct set of information is properly grouped. Cohesion is well managed throughout, easily satisfying the requirements for a Band 8 score.
Lexical Resource — Band 7.5
The student demonstrates a wide and flexible lexical resource appropriate for an academic task. Advanced vocabulary items and collocations are used skillfully, such as 'near-ubiquity', 'practically non-existent', 'exceptionally rapid growth', 'saturation', and 'leveling off'. Word choices are precise, and there are virtually no spelling or lexical errors. The vocabulary allows the writer to convey precise meanings and statistical trends fluently and naturally, aligning closely with the descriptors for Band 8.
Grammatical Range and Accuracy — Band 7.5
A wide range of complex grammatical structures is employed with a high degree of accuracy. The student utilizes participial phrases ('possessing by 40%', 'dropping to 20 hours'), subordinate clauses ('As the percentage of households... surged'), and varied sentence openings. The vast majority of sentences are completely error-free, with only very occasional minor slips that do not impede communication. Punctuation and control over tense consistency across historical timelines are maintained expertly. This level of grammatical control fully warrants a Band 8.
