Each of the four criteria is scored on a scale from 0 to 9. The scores from each criterion are averaged to calculate the final score for Writing Task 1. For example, if a candidate scores 7 for Task Achievement, 8 for Coherence and Cohesion, 6 for Lexical Resource, and 7 for Grammatical Range and Accuracy, the final score would be calculated as follows:

Final Score = 7 + 8 + 6 + 7 = 28 / 4 = 7

In conclusion, candidates must focus on all four criteria to achieve a high score in IELTS Writing Task 1 for General Training. By addressing the task fully, organizing their writing coherently, using a varied vocabulary accurately, and employing a range of grammatical structures, candidates can enhance their performance and improve their chances of achieving their desired band score.
