IELTS Writing Task 1 question
The parents of your Australian friend Chris have invited you to a surprise birthday party for him/her. Write a letter to Chris's parents. In your letter:
- say why you think Chris will enjoy the surprise party
- explain why you won't be able to attend the party
- give details of a plan to see Chris at a different time
You do NOT need to write any addresses.
Begin your letter as follows:
Dear Mr and Mrs Collins,
Student answer (Band 7.5)
Dear Mr. and Mrs. Collins,
I hope you are both doing well. Thank you very much for inviting me to Chris's surprise birthday party. I am sure he will be delighted by this wonderful celebration because he always enjoys spending quality time with his family and close friends. He will also appreciate the effort and love everyone has put into arranging it.
Unfortunately. I will not be able to attend the party because I have an important family commitment on that day which I cannot cancel. I am truly sorry for missing such a meaningful occasion, and I would appreciate it if you could pass my best wishes to Chris.
However, I would love to meet Chris at another time. I am planning to visit him next weekend, and we can go out for dinner, or spend some time together. I will also bring a small birthday gift for him and celebrate with him personally.
Please give Chris my warm regards and wish him a very happy birthday.
Yours sincerely,
Alex James

Task Achievement / Task Response — Band 7.5
You have fully addressed all three bullet points in the prompt. You clearly explained why Chris would enjoy the party, provided a plausible reason for your absence, and offered a concrete plan to meet him later. The tone is consistently appropriate for a letter to a friend's parents, maintaining a polite and warm register throughout. The ideas are well-developed and the purpose of the letter is clear from the beginning. You have successfully met all the requirements of the task.
Coherence and Cohesion — Band 7.5
The letter is logically organized with a clear progression of ideas. Each paragraph focuses on a specific point from the prompt, which makes the structure easy to follow. You have used appropriate cohesive devices such as 'However', 'Unfortunately', and 'because' to link your thoughts effectively. The paragraphing is logical and contributes to the overall clarity of the message. The flow between the apology and the alternative plan is smooth and natural.
Lexical Resource — Band 7.0
You demonstrate a good range of vocabulary that is well-suited to the context of a personal letter. Phrases like 'delighted by this wonderful celebration', 'meaningful occasion', and 'quality time' are used accurately and naturally. While the vocabulary is sufficient and appropriate, incorporating a few more sophisticated collocations or idiomatic expressions could elevate the response further. There are no spelling or word-choice errors, and the language used is precise and conveys your meaning clearly.
Grammatical Range and Accuracy — Band 7.5
Your grammar is generally very accurate, with a good mix of simple and complex sentence structures. For example, 'I am sure he will be delighted... because he always enjoys...' shows good control over subordinate clauses. There is one minor punctuation error where a period is used instead of a comma after 'Unfortunately', but this is a minor slip that does not impede communication. The majority of your sentences are error-free, and your control over tense and subject-verb agreement is consistent throughout the letter.
