Problem-solution essays scare students more than they should. You see the word "problem" in the question and your brain freezes up. But here's the truth: these essays follow a predictable structure, and once you understand it, you'll write faster and score higher.
This guide walks you through exactly how to tackle an IELTS Task 2 problem solution essay with real examples and the specific mistakes that cost you band points.
The IELTS examiner wants you to identify a problem and propose one or more solutions. Straightforward. The trap? Treating it like a discussion essay or an argument essay.
You're not debating whether the problem exists. You're not sitting on the fence. You're diagnosing the issue and prescribing fixes. Examiners want to see if you can think critically and structure your ideas clearly.
A real IELTS question might look like this:
"In many countries, plastic waste is a major environmental problem. What are the causes of this, and what solutions can you suggest?"
Notice what they're asking: causes (the problem) and solutions (the answer). You need both. That's the contract.
High-scoring essays almost always follow this format.
This structure gives you roughly 320-400 words. Aim for 400-450 words instead. You'll have room to develop ideas without repeating yourself. IELTS Task 2 essays should be at least 250 words, but Band 7+ responses typically sit between 400 and 500 words.
Your introduction sets the tone. If it's vague, the examiner expects vagueness everywhere. If it's sharp, they lean in.
Weak: "There are many problems in the world today. One of them is plastic waste. This essay will discuss the problem and the solution."
Why weak? It's generic. It could apply to any essay on any topic. The examiner has seen this opener 50 times.
Strong: "Plastic waste has become a significant environmental threat, with single-use packaging contaminating oceans and landfills at unprecedented rates. The causes stem from both consumer habits and inadequate waste management infrastructure. This essay will examine these root causes and propose practical solutions at both individual and governmental levels."
Better because it's specific. You've named the problem, acknowledged its causes, and mapped out what's coming. This demonstrates task response (you understand the assignment) and coherence (your ideas connect).
Quick tip: Don't use "this essay will discuss" more than once. Swap in alternatives: "this essay explores," "the following paragraphs examine," or just state it directly: "The root causes are X, and viable solutions include Y."
You have two options: discuss the problem itself, or discuss its causes. Many questions ask specifically for causes, so read the prompt word-by-word.
Structure it like this: topic sentence that names the problem, two or three supporting sentences that develop the idea, then a linking sentence that points toward solutions.
Strong: "The primary cause of plastic waste accumulation is the global reliance on single-use packaging for convenience and cost-efficiency. Manufacturers favor plastic because it's cheap, lightweight, and durable, which makes products affordable for consumers. Additionally, consumers themselves purchase these goods without considering disposal, creating a cycle where production outpaces recycling capacity. In developing nations particularly, waste management infrastructure cannot handle the volume, leading to landfill overflow and ocean pollution."
Notice the specificity: "single-use packaging," "cheap, lightweight, and durable," "developing nations," "landfill overflow and ocean pollution." These details earn you points under lexical resource (you're using topic vocabulary accurately) and task response (you're actually answering the question, not speaking in generalities).
Weak: "Plastic waste is a big problem. There's too much of it. People use plastic bags and bottles and don't throw them away properly. Companies make a lot of plastic things."
Vague. Repetitive. No progression. This tanks your score on coherence and grammatical range.
This is where you show you can think beyond the problem. Skip vague solutions like "people should be more responsible" or "the government should do something." Be specific. Tell us HOW and WHY.
Strong: "Two practical solutions can mitigate this crisis. First, governments should implement extended producer responsibility (EPR) laws, which require manufacturers to manage the full lifecycle of their packaging, incentivizing them to use less plastic. Second, investment in waste infrastructure is essential; modern sorting facilities and chemical recycling technologies can convert existing plastic waste into raw materials, creating a circular economy. Consumer education campaigns paired with plastic bans on specific items, such as single-use bags, have already shown a 30% reduction in plastic consumption in countries like France and the UK."
See the difference? We moved from "people should be responsible" to "extended producer responsibility laws," "chemical recycling technologies," "circular economy," and specific examples with data. This is Band 7 territory.
Real talk: If you don't know exact statistics, don't invent them. Use phrases like "research suggests," "studies indicate," or "trials have demonstrated." Making up data loses you points. Being honest about what you know gains them.
These three errors appear in roughly 60% of student essays and they directly damage your band score.
Mistake 1: Confusing problem-solution with argument essays. An argument essay asks you to agree or disagree. A problem solution essay doesn't. You're not taking sides; you're solving. Don't write "Some people believe X, but others believe Y." Write "The problem is X. The solution is Y."
Mistake 2: Proposing unrealistic or vague solutions. "Everyone should recycle" isn't a solution. It's a platitude. Real solutions identify who does it, how they do it, and why it works. "Government-funded recycling programs with weekly collection and citizen education" is a solution.
Mistake 3: Spending too much time on the problem and running out of space for solutions. You have 40 minutes. If you've written 200 words on the problem and only 80 on solutions, you've mismanaged badly. Balance both sections roughly equally.
Pro move: Spend the first 3-4 minutes planning. Write a quick outline: Problem (1-2 sentences), Cause 1, Cause 2, Solution 1, Solution 2, Conclusion. This saves you 10 minutes of rambling later.
Coherence and cohesion is worth 25% of your writing score. You can have perfect grammar and vocabulary, but if your ideas don't connect, you'll cap out at Band 6.
Use transition words strategically. Here are connectors that work specifically for problem-solution essays:
Example: "Air pollution in cities stems from vehicle emissions and industrial output. By implementing congestion pricing and transitioning to electric buses, governments can reduce emissions by up to 40%."
See how "by implementing" connects the cause to the solution? That's coherence in action. For more help analyzing your writing structure, try our free essay grading tool, which provides detailed feedback on your task response and coherence.
Example 1: "Many countries are experiencing rapid urbanization. What problems does this cause, and what solutions would you recommend?"
You're asked for multiple problems. Don't list them vaguely. Pick two strong ones: housing shortages and infrastructure strain. Then propose solutions for each. Infrastructure strain can be solved by urban planning and public transit investment. Housing shortages can be addressed through zoning reform and government-subsidized construction.
Example 2: "In many countries, young people are moving away from rural areas to cities. What are the causes of this trend, and what could be done to address it?"
This asks for causes (economic opportunity, lack of services in rural areas) and what could be done (government incentives, rural broadband, job creation). Notice the second part isn't asking for solutions to the problem itself, but actions to reverse the trend. Read the question carefully. If you need more practice, explore common IELTS essay topics to prepare across different problem-solution scenarios.
Critical move: Underline or highlight the action verbs in the question: "What problems?" "What solutions?" "What could be done?" These tell you exactly how many paragraphs you need and what to cover. Miss this and you'll answer the wrong question.
Your conclusion shouldn't recycle your introduction word-for-word. The examiner already knows the problem exists. They want to see you wrap up with confidence and insight.
Weak: "In conclusion, plastic waste is a problem. It is caused by single-use packaging and lack of recycling. The solutions are EPR laws and better waste management infrastructure. This essay discussed the problem and solutions."
This just regurgitates the entire essay in four sentences. No insight. No confidence.
Strong: "While plastic waste remains a complex challenge, the combination of regulatory frameworks like EPR and infrastructure investment provides a viable path forward. Success will depend on the commitment of both governments and consumers to act. Without these coordinated efforts, environmental degradation will accelerate, making immediate action not just beneficial, but essential."
This conclusion restates the solution approach, acknowledges shared responsibility, and elevates the stakes. It feels like an ending, not a repeat.
