You're staring at your letter. It feels good. But is it actually Band 8, or are you fooling yourself?
Here's the thing: most students can't evaluate their own work fairly. You either think everything you write is brilliant, or you tear it apart for no reason. Neither helps. This IELTS letter evaluation checklist fixes that. It's built on the actual IELTS band descriptors, not random internet advice. By the end of this post, you'll know exactly what examiners are looking for, and you'll have a real system to check your letters before you submit them.
You probably read your letter once, check for spelling mistakes, and call it done. That's not evaluation. That's hope.
IELTS examiners read differently than you do. They're checking four specific things: Task Response (did you answer what was asked?), Coherence and Cohesion (does it flow logically?), Lexical Resource (how varied is your vocabulary?), and Grammatical Range and Accuracy (how complex and correct is your grammar?). Each gets a score from Band 5 to Band 9. Your final mark is the average of these four scores. If you're only checking spelling, you're missing 75% of what matters.
Band 8 letters aren't just correct. They're sophisticated, strategic, and natural-sounding. They show range. They show control. Most students write Band 6 letters and wonder why they don't jump to Band 8. The answer: they never knew what to look for.
Let me be blunt. If you fail Task Response, your other scores don't save you. You could have perfect grammar and still get Band 6 overall if you didn't fully address the prompt.
IELTS letters come in three types: complain, request information, or explain a situation. Each needs specific content. An exam question might say: "Write a letter to your landlord. You've had problems with noise from the neighbours. Ask them to help you resolve this." That's a complaint letter that requires action from the recipient.
Band 8 Task Response looks like this: you cover all bullet points with full detail, you extend ideas beyond the bullet points naturally, and you show awareness of purpose (your tone matches the situation). You're not just ticking boxes. You're writing like a real person in that situation would write.
Weak (Band 5-6): "I am writing to tell you about the noise. The neighbours make noise at night. This is a problem. Please help me."
Strong (Band 8): "I am writing to bring to your attention a recurring issue that has significantly affected my quality of life. Over the past three weeks, my neighbours in Flat 4B have been playing loud music and hosting gatherings that typically last until well past midnight. This has disrupted my sleep schedule and impacted my ability to work from home effectively. I would appreciate it if you could contact them directly and remind them of the noise restrictions outlined in our lease agreement."
Notice the difference? The Band 8 version gives specific examples (Flat 4B, three weeks, midnight), explains the impact (sleep disruption, work problems), and makes a clear, reasonable request (contact them, remind them). It's not vague. It's specific enough that the landlord could actually take action.
Tip: For every bullet point, write down the main idea you'll cover. Then write down at least one specific detail or example you'll add. That detail often pushes you from Band 6 to Band 7.
A Band 8 letter reads smoothly. You move from one idea to the next logically, and you use linking words that feel natural, not forced.
This is where most students mess up. They use too many linkers, or they use them wrong. "I went to the shop. Furthermore, I bought milk. Moreover, I also purchased bread." That's Band 5. It's choppy and repetitive.
Band 8 uses linkers sparingly and strategically. It also uses other cohesion techniques: pronoun reference, lexical cohesion (repeating or substituting key words), and paragraph structure.
Here's what you're evaluating:
Weak: "I attended your training programme. The programme was helpful. The programme taught me many skills. I recommend this programme to others."
Strong: "I attended your training programme last month. It was incredibly valuable, particularly the sections on project management and team communication. I would recommend it to anyone in my organisation."
The Band 8 version doesn't repeat "programme". It uses "it" and then just mentions the organisation. It reads like actual English. The weak version sounds like someone learning the language, not someone fluent in it.
Band 8 vocabulary isn't just fancy words thrown in randomly. It's precise, appropriate, and varied.
The examiners ask: Do you use topic-specific vocabulary? Do you use less common words correctly? Can you express the same idea different ways? Do you avoid repeating common words?
In a complaint letter, Band 8 writers use: persistent issue, recurring problem, disruptive behaviour, impact my ability to, warrant immediate attention, resolve this matter. They don't use: bad, annoying, make me sad, please help.
Weak: "I am very angry about what happened. The staff were rude to me. This is not good. I want you to do something about it."
Strong: "I am deeply disappointed by the unprofessional conduct displayed by your staff. Their dismissive attitude was entirely unwarranted and undermined the service I expected. I trust you will address this matter promptly to prevent future occurrences."
The strong version uses: disappointed (more sophisticated than angry), unprofessional conduct (specific), dismissive attitude (precise), undermined (showed the consequences), and occurrences (formal, singular noun replacing "this happening again").
Here's your evaluation question: If I crossed out the main content words (nouns, verbs, adjectives), could someone tell my topic from the vocabulary alone? If not, you're using too much basic vocabulary. Aim for 15-20% of your vocabulary to be less common but completely appropriate. That's Band 8 range.
Tip: Highlight every verb, adjective, and adverb in your letter. Ask yourself: could I use a more specific or sophisticated word here? Can I replace a phrasal verb (like "look up") with a single word (like "investigate")? That simple habit lifts your vocabulary band by half a point.
Band 8 grammar isn't about avoiding mistakes. It's about using a variety of structures correctly, especially complex ones.
Examiners count errors per 100 words. Band 8 allows maybe 2-3 minor errors across a 150-word letter. Zero errors is actually suspicious. It often means you're playing it safe with simple structures.
Band 8 range means you use: complex sentences with dependent clauses, passive voice appropriately, mixed tenses (past, present, future as needed), a variety of sentence types. You're not writing five sentences that all follow "Subject + Verb + Object".
Weak: "I received your email. I read it. It was about the job. I want to apply for it. I have the skills. I have experience. I think I am right for it."
Strong: "Thank you for informing me of the vacancy. Having reviewed the job description, I believe my background in project management and proven track record in delivering results make me an ideal candidate. I would welcome the opportunity to discuss how my expertise aligns with your organisation's needs."
The weak version uses seven simple sentences. Each follows the same pattern. The strong version uses: a dependent clause (Having reviewed...), passive construction (make me), and complex noun phrases (proven track record, my expertise). It's varied. It's sophisticated. It shows grammatical control.
Your evaluation checklist for grammar:
Tip: After writing your letter, rewrite the first sentence using a dependent clause or more complex structure. Then do the same for the last sentence. That small change often pushes two sentences from Band 6 to Band 7 grammatically.
Use this after you write. Be honest with yourself. This is how to evaluate IELTS letters systematically.
Task Response
Coherence and Cohesion
Lexical Resource
Grammatical Range and Accuracy
You think you're at Band 8. You're actually at Band 7. Here's why.
Mistake 1: Overusing linking words. You learned "furthermore", "moreover", "in addition" and you use them constantly. Stop. Band 8 writers use linkers strategically, not obsessively. A 150-word letter should have 4-5 linkers maximum.
Mistake 2: Using fancy vocabulary incorrectly. You look up synonyms and pick the most sophisticated word without checking if it fits the context. "This situation has precipitated my decision to write" sounds impressive but feels weird in a casual request letter. Use sophisticated vocabulary accurately, not just impressively.
Mistake 3: Playing it too safe with grammar. You use only simple sentences because you're afraid of errors. But Band 8 requires grammatical range. Risk it. Use complex structures. Make the occasional error. An error with complexity beats perfect simplicity every time.
Mistake 4: Missing tone shifts. You're polite throughout a complaint letter. Band 8 complaint letters are polite but firm. There's a difference. You should show that you're disappointed or that this is serious, not just nicely asking for help. If you're unsure about tone, check out our guide on letter tone for specific examples of where tone matters most.
Don't evaluate all four criteria at once. You'll miss things. Do it in this order. The whole process takes 25 minutes and it's worth every second.
Step 1 (5 minutes): Read your letter once without marking anything. Just get a feel for it. Does it sound natural and fluent?
Step 2 (5 minutes): Check Task Response. Did you answer the question? Highlight the parts where you address each bullet point. Did you add specifics? If not, add them now.
Step 3 (5 minutes): Check Coherence and Cohesion. Mark your paragraph breaks. Do they make sense? Mark your linkers. Are there too many or too few? Are your ideas connected logically?
Step 4 (5 minutes): Check Lexical Resource. Highlight every adjective and verb. Ask yourself: could any of these be more specific or sophisticated? Replace 2-3 of them with stronger alternatives.
Step 5 (5 minutes): Check Grammatical Range and Accuracy. Mark every sentence starting with "I". If you have more than three, rewrite some to vary your sentence openings. Check tenses. Count errors.
You'll catch problems before an examiner sees your work. That's the entire point.

Check My Letter FreeLet's put this IELTS task 1 letter checker to work. Here's a sample complaint letter. Use the checklist and see if you'd give it Band 8.
Sample Letter:
Dear Manager,
I'm writing because I had a bad experience at your restaurant last Saturday. I booked a table for six people at 7 PM. When we arrived, the staff told us there was no table ready. We waited 45 minutes. This was very frustrating because we had made a reservation in advance.
During our meal, the food was cold. The waiter didn't apologise or offer to replace it. We were very disappointed with the service. The prices were expensive but the quality wasn't good.
I would like you to explain why this happened. I would also like a refund. If you don't respond, I'll leave a negative review online.
Yours truly,
John
Now evaluate it yourself using the checklist. Don't scroll yet. Seriously, try it.
...
Here's my evaluation.
Task Response (Band 6): The letter addresses the complaint and requests action, but it lacks specifics. Which restaurant? Where? "Bad experience" is vague. "Very frustrated" and "very disappointed" are repeated emotions without examples. A Band 8 letter would mention what the waiter's name was, what dish was cold, why 45 minutes mattered (missing a show, important dinner). It would also avoid threats like "I'll leave a negative review". That sounds aggressive, not professional.
Coherence and Cohesion (Band 6): The letter has three paragraphs, which is good. But the ideas jump around. Paragraph 1 is about the wait. Paragraph 2 combines cold food and service. Paragraph 3 combines demands and threats. A Band 8 letter would have clearer flow: what happened (paragraph 1), impact (paragraph 2), and what you want (paragraph 3). Also, "this was very frustrating because we had made a reservation" is stated twice. That's repetition without purpose.
Lexical Resource (Band 5): The vocabulary is basic. "Bad", "very frustrated", "very disappointed", "didn't apologise", "quality wasn't good" are Band 5-6 words. There's no topic-specific vocabulary for a restaurant complaint. A Band 8 letter would use: substandard service, inadequate facilities, unacceptable delays, compromise my dining experience, warrant compensation. Also, "didn't apologise" should be "failed to apologise" or "made no attempt to remedy the situation".
Grammatical Range and Accuracy (Band 6): The grammar is correct, but every sentence is simple. "I booked. We arrived. The staff told us. We waited." It's all Subject-Verb-Object. There's one complex sentence ("because we had made a reservation"), but that's it. A Band 8 letter would have dependent clauses, passive voice, varied sentence openers. Example: "Having made a reservation well in advance, I was astonished to find no table prepared upon our arrival" is much stronger than "I booked a table. When we arrived, the staff told us there was no table ready."
Overall: Band 6. It answers the question but with basic language, simple structure, and vague details.
This is the gap between Band 6 and Band 8. Now you know what to look for in your own letters.
The sample letter above has another problem: it doesn't feel professional. The writer threatens a negative review. They sound angry, not disappointed. Band 8 complaint letters show dissatisfaction without aggression. You're firm but respectful. Understanding complaint letter tone is actually a separate skill that affects both your Task Response and your Coherence score.
A Band 8 complaint letter says: "I trusted you and you let me down. Here's why and what I'd like you to do about it." It doesn't say: "Your service was terrible and if you don't fix it I'll destroy your reputation."
Print this checklist. Write a letter. Evaluate it using the five-step process. Be honest about where you fall short. Then rewrite those sections and evaluate again. Use our IELTS writing checker to get detailed feedback on all four scoring criteria. That's how you actually move from Band 6 to Band 8.
