Salary comparison charts show up on IELTS exams constantly, and most students describe them badly. You'll get a bar chart, line graph, or table showing earnings across job titles, industries, or years, and you've got 20 minutes to write 150+ words. Sound familiar?
Here's the real problem: students either state obvious facts ("Engineer earns more than nurse") or they bury themselves in numbers without any structure. Neither gets you past Band 6. To break through, you need a system that combines accurate data selection, precise comparison language, and clear organization. This post gives you that system, plus real examples showing exactly where students go wrong and how to use an IELTS writing checker to catch mistakes before exam day.
Salary data looks simple on the surface. Numbers are numbers, right? Wrong. The IELTS examiner isn't marking you on math skills. They're marking you on your ability to pick out relevant data, compare trends, and describe patterns in clear, sophisticated English.
Most students make three specific mistakes when describing salary data:
When you fix these three things, your score jumps noticeably. Band 6 writers list facts. Band 7+ writers analyze patterns and use sophisticated comparative structures. Let's look at what that actually looks like.
You've got maybe 8 to 12 key data points to work with in a 150-word response. Don't describe all of them.
Instead, scan for these patterns first:
Let's say you get a bar chart with five professions: surgeon ($250k), lawyer ($180k), teacher ($55k), nurse ($65k), and electrician ($85k).
What do you actually highlight? Not every number. Instead: surgeons earn significantly more than all other professions (there's your biggest gap); teachers earn the least (your minimum point); and skilled trades like electricians fall somewhere between teachers and lawyers (that's your grouping).
Tip: Before you write a single sentence, underline the three biggest story points in the data. That's your skeleton. Everything else is supporting detail.
This is where most students lose marks on Lexical Resource. You can't use "is higher" five times in 150 words and expect a good score on an IELTS essay checker or with a live examiner.
Here's a real comparison:
Weak: "Surgeons earn $250,000. This is higher than lawyers. Lawyers earn $180,000. Teachers earn $55,000, which is lower than nurses who earn $65,000."
This reads like a list. Zero sophistication. You're just repeating data instead of actually comparing anything.
Good: "Surgeons command the highest salaries at approximately $250,000 annually, significantly outearning lawyers by roughly $70,000. In contrast, teachers represent the lowest-paid group, earning just over half the salary of nurses, who themselves earn substantially less than skilled trades workers such as electricians."
See the difference? The strong version uses varied sentence structures, specific comparative verbs (outearning, represent), and proportional language (half the salary, substantially less). You're painting a picture of the data, not just listing facts.
Here are specific phrases to swap in instead of repeating "is higher/lower":
Use these deliberately. If you see a chart with five professions, don't describe them in order. Group them instead: "The top earners, surgeons and lawyers, significantly outpace the remaining three professions, which cluster between $55,000 and $85,000."
If your chart shows salary data across multiple years or decades, examiners expect you to describe change, not just compare static values. This is where many Band 5/6 responses fall short when attempting salary chart corrections.
Look for these trend patterns:
Example: A line graph shows teacher and nurse salaries from 2000 to 2024. In 2000, both earned roughly $35,000. By 2024, nurses earned $65,000 while teachers earned $55,000.
Weak: "In 2000, teachers and nurses earned the same. In 2024, nurses earn more. The nurse salary went up more than the teacher salary."
Good: "Although teachers and nurses started at parity in 2000, a divergence emerged over the subsequent two decades. Nursing salaries rose more steeply, reaching $65,000 by 2024, whereas teaching salaries increased more gradually, reaching only $55,000 in the same year. This widening gap reflects shifting demand in healthcare sectors."
The strong version names the trend (divergence), gives timing (two decades), compares rates of change (steeply vs. gradually), and even hints at why this happened. That's Band 7 thinking.
You've got 150+ words and about 20 minutes. Don't waste time on flowery introductions. Move fast.
Paragraph 1 (1-2 sentences): State what the chart shows and what timeframe or categories it covers. Keep it simple. "The bar chart illustrates annual salaries across five professions in the United States." That's it.
Paragraph 2 (4-6 sentences): Describe the most significant patterns. Highest and lowest earners. Major gaps. Any surprises. This is where you use your varied comparative language from earlier.
Paragraph 3 (2-3 sentences): If there's time-based data, describe the change. If it's static data, add minor detail (where groups cluster, secondary patterns). Keep it tight.
That's it. Examiners mark you on Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. Your job is to select relevant data (Task Response), organize it logically (Coherence & Cohesion), use varied vocabulary (Lexical Resource), and write grammatically correct sentences (Grammatical Range & Accuracy). A three-paragraph structure does all four if you execute it right.
Tip: Write your opening sentence in 15 seconds. It's just context. Your entire Task Response score comes from paragraphs 2 and 3, so spend 80% of your time analyzing and comparing there.
Even students with good comparative language lose marks for careless errors. Here are the ones that tank your band score.
Subject-verb agreement with data: "The salary data shows" (not show). "The group of professionals earns" (not earn). Pick one verb form and stick with it throughout.
Prepositions with comparisons: It's "compared to" or "compared with", never "compared than". "Nurses earn more than teachers" is correct, but "Nurses earn more in comparison to teachers" is awkward and wordy.
Articles with superlatives: Always use "the". "The highest-paid profession" (not "highest-paid profession"). "The lowest earners" (not "lowest earners").
Weak: "The data shows that surgeons earns the most money compared than other jobs."
Good: "The data shows that surgeons earn the most, compared to all other professions."
That second version is tighter, grammatically correct, and uses proper preposition pairing. Small corrections like this add up to actual band score increases.
After you write, ask yourself these five questions in order:
If you answer "no" to any of these, you've found your revision target. Fix it before submitting. Many students find it helpful to paste their response into an IELTS writing correction tool to catch grammar errors they might miss on their own.
Tip: Use a highlighter to mark every instance of your comparison language. If it looks repetitive, you'll see it immediately. Then replace the weaker phrases with ones from the list earlier in this post.
Let's walk through a real scenario. Here's the chart: A bar chart compares median annual salaries in the UK for six professions in 2023: Doctor ($95k), Software Engineer ($75k), Accountant ($65k), Teacher ($38k), Retail Manager ($42k), Construction Worker ($55k).
First, identify the patterns. Doctors earn the most (your outlier). Teachers earn the least. Software engineers and accountants form a mid-tier cluster. Construction workers and retail managers occupy a lower-middle band.
Now write:
"The bar chart compares median salaries across six UK professions in 2023. Doctors command the highest earnings at $95,000 annually, significantly outpacing all other professions. Software engineers and accountants form a distinct mid-tier group, earning between $65,000 and $75,000, which substantially exceeds the lower-paying roles. Teachers represent the lowest-paid group at $38,000, followed by retail managers at $42,000. Construction workers, despite requiring skilled trades training, earn only marginally more at $55,000. The data reveals a considerable salary hierarchy, with medical professionals earning more than double the income of teachers."
What makes this work? Specific vocabulary (command, outpacing, form a distinct group, represent). Clear grouping (not six separate sentences). Proportional comparison (more than double). No fluff. It flows logically and compares multiple values in sophisticated ways.
