🧠 “Tense is not just grammar—it’s a signal to the examiner that you understand time and context in data.”

One of the most overlooked but crucial elements in Academic Task 1 is tense accuracy. The wrong tense can confuse the reader or misrepresent the data, which affects both your Task Achievement and Grammatical Range & Accuracy scores.

🔍 Why Tense Matters

IELTS examiners assess how well you accurately describe visual information, and part of that means respecting the timeframe provided in the graph or chart.

Failing to use the correct tense:

❌ Makes your description inaccurate
❌ Confuses the examiner about the timeline
❌ Can reduce your band score in grammar and coherence

🕵️‍♂️ How to Choose the Right Tense

Data Type	Use This Tense
📅 Past time data (e.g., 1990–2020)	Past simple: “Sales increased”, “Population grew”
📈 General facts/trends	Present simple: “Water boils at 100°C”, “The sun rises in the east”
📊 No date provided (but refers to a completed situation)	Present simple or past depending on logic
🔮 Future projections (e.g., 2025 forecast)	Future: “It is expected that…”, “will rise”

📘 Examples by Context

🗓️ Example 1: Past Data

The number of tourists increased from 1 million in 2000 to 3 million in 2010.

✔️ Past Simple is used because the action occurred in a specific, completed timeframe.

🌍 Example 2: General Facts

The pie chart shows that most people prefer email over other communication methods.

✔️ Present Simple fits here because no date is given and it reflects a current preference.

🔮 Example 3: Predictions

The population of urban areas is expected to double by 2030.

✔️ A future construction shows you’re describing a forecast.

🧠 Common Mistake to Avoid

❌ The number of students increased in 2030.

🔁 This mixes past simple with a future year. It’s inaccurate.

✅ The number of students is expected to increase in 2030.

✔️ Now it’s grammatically correct and context-appropriate.

📝 Pro Tip: Use Passive Voice for Future Predictions

The use of smartphones is predicted to rise dramatically.

Passive forms like “is predicted to…”, “is expected to…”, and “is likely to…” are perfect for neutral, academic tone.

🧩 Checklist Before You Write

✅ Look at the timeline — what years are shown?
✅ Ask: Is this past, present, or future data?
✅ Choose your tense before writing your overview and details.
✅ Maintain tense consistency within paragraphs.

📌 Quick Practice: Which Tense?

Question:
A line graph shows birth rates in Canada and the UK from 1970 to 2020.

Write the correct version:

❌ The birth rate rises sharply in Canada between 1980 and 1990.

✅ The birth rate rose sharply in Canada between 1980 and 1990.

🎯 Why? → The action is completed in the past = past simple needed.
