The PTE Describe Image Process question can look difficult when the diagram contains several stages, arrows, labels, or connected steps. However, there is no need to explain every small detail. A clear structure, suitable linking words, and accurate process vocabulary can make the response much easier to organise.

In this task, the main goal of PTE Describe Image Process is to explain what the image shows in a clear and logical order. Instead of memorising a long answer, focus on identifying the beginning, the main stages, and the final result.

This guide explains how to describe a PTE process diagram with simple templates, useful vocabulary, and sample answers.

A process diagram shows how something happens from one stage to another. It may describe a natural process, a manufacturing system, a recycling method, a production cycle, or the movement of a product or material.

Types of PTE Describe Image Process Diagrams

Before writing, examine the diagram carefully and identify the type of process.

1. Life Cycle Process

A life cycle describes a natural or biological process that usually repeats continuously.

ExampleL The life cycle of a butterfly.

2. Linear Process

A linear process shows a series of stages from beginning to end.

Stage 1 → Stage 2 → Stage 3 → Stage 4 → Final Stage

3. Recycling Process

A recycling process explains how a material is collected, processed, and used again.

Collection → Sorting → Processing → Production → Reuse

4. Cyclical Process

A cyclical process shows stages that repeat continuously, with the final stage eventually returning to the beginning.
