Overview
In IELTS Academic Writing Task 1, you may be presented with a process diagram that visually explains how something works, is produced, or changes over time.
This process can either be natural(like the life cycle of a butterfly), or it can be man-made(the manufacturing of bricks).
Your main task is to describe each stage shown in the diagram accurately, following the correct sequence, and to explain how the different stages are connected to each other.
It is important to maintain a clear, logical flow of information so that the reader can easily understand how the process progresses from beginning to end.

Sample Question
✅Key Characteristics:
- You need to describe each step in the process in the correct order.
- You must write at least 150 words, and complete the task in about 20 minutes.
- Start with an introduction — rewrite the question using your own words.
- Then write an overview — give a simple summary of what the process shows – general process or final result(e.g., what is being made or what natural cycle is shown).
- Use sequence words to show the order: First, Next, Then, After that, Finally.
- For man-made processes, use the passive voice (e.g., The materials are mixed, The bricks are baked).
- For natural processes, use the active voice (e.g., Water evaporates, Rain falls).
- Mention all the stages — do not skip any, even if they seem small.
- Use clear and formal language — do not give personal opinions or reasons.
- Use linking words to show how one step leads to another (e.g., as a result, following this).
- Diagrams may include arrows, labels, or cycles, so describe them carefully.
- The writing must be purely descriptive, focusing on what is shown, not on why it happens or how it could be improved.

⭐️ Important Tips :
- Understand the diagram clearly before writing — follow the arrows or flow carefully.
- Always check the title and labels in the diagram. If there’s no time reference, use present simple.
- You are usually describing a process that is regular, repeated, or always true. So, you should normally use the present simple tense.
- Spend 2–3 minutes planning before writing.
- Describe each step in order — do not skip or mix steps.
- Follow the sequence exactly as shown in the diagram.
- Use linking words to connect stages smoothly.
- Do not include personal opinions or unnecessary details.
- Follow the sequence exactly as shown — do not skip or rearrange steps.
- Use passive voice when describing actions (e.g., “The water is collected.”).
- Use linking words: Initially, Then, After that, Subsequently, Finally.
- Be formal and factual — no opinions or reasons.
- Focus on key stages, not tiny details.
- Keep sentences clear and organized.
- Check grammar and spelling before finishing.
