10 IELTS Spelling Mistakes Candidates Make, and How to Fix Them Fast

Most IELTS candidates who miss their target band blame grammar, ideas or nerves. Spelling rarely makes the list, because it feels too small to matter. Yet it touches three of the four papers. In Listening and Reading, a misspelled answer scores exactly what a blank does. In Writing, spelling sits inside Lexical Resource, which is a quarter of the mark for each task.
The good news is that spelling mistakes in IELTS are not random. The same ten kinds turn up again and again, in candidates from every country and at every level, and each one has a fix you can start today. This guide goes through them one by one: what the mistake looks like, why it happens, and a short drill that removes it. At the end there is a two-week plan that puts the drills together.
Everything here is checked against the official IELTS materials as they stand in 2026, including the public Writing band descriptors (last revised in May 2023) and the published score tables.
How spelling is actually marked
Listening and Reading. Each paper has 40 questions worth one mark each. For any answer you write in words, the spelling has to be right. The marker compares your answer with the key, and "accomodation" does not match "accommodation". There is no half mark for being close.
The margins are thin. The official IELTS score tables give, as a rough guide, 30 correct answers for band 7 in Listening and Academic Reading, and 35 for band 8. The exact numbers shift slightly from one test version to the next. Even so, two or three spelling slips on answers you understood perfectly can be the whole distance between two half bands.
Writing. The examiner scores each task on four equally weighted criteria, and Task 2 counts twice as much as Task 1. Spelling belongs to Lexical Resource. The public descriptors are worth reading in the original, because they are more forgiving and more precise than most prep material suggests. At band 7, "there are only a few errors in spelling and/or word formation and they do not detract from overall clarity". At band 6, "there are some errors in spelling and/or word formation, but these do not impede communication". At band 5, errors "may be noticeable and may cause some difficulty for the reader".
So the question is never simply how many mistakes you made. It is whether the examiner notices them and whether they get in the way.
Speaking. Spelling is not assessed at all.
Mistake 1: Misspelling the words every essay needs
Open a band 6 Task 2 script and you will usually find the same small set of casualties: goverment, enviroment, developement, oppurtunity, technolagy. These are not rare words. They are the working vocabulary of IELTS topics, and because they appear several times in one essay, a single wrong habit becomes three or four visible errors.
Most of them go wrong in the same place: the unstressed middle, where a vowel collapses into a vague "uh" and a consonant disappears in fast speech. People say "guv-ment" and "en-vy-ment", and the hand writes what the ear heard.
The fix is to learn them through their parts. Government is govern plus ment, so the n cannot vanish. Environment is environ plus ment. Development is develop plus ment, with no e after the p. Once you see the base word inside, the spelling stops being a guess.
Drill (five minutes). Choose eight topic words you know you will need. Say each one aloud, cover it, write it from memory, then check it letter by letter. Write one sentence that uses two of them. Repeat on three days in the same week, and only move a word off the list when you have written it correctly on two separate days.
Mistake 2: Mixing British and American spelling
IELTS accepts both British and American spelling. Colour and color, centre and center, organise and organize are all correct. You gain nothing by switching to British forms because the test has British roots, and you do not need to.
The real risk is mixing the two. An essay that says organise in one paragraph and organization in the next looks less controlled, and a hybrid inside a single word, such as colur, is simply wrong in both systems. The official materials do not name a penalty for switching, but consistency costs nothing, so make it a habit.
Pick the system you already use most. Write it at the top of your practice notebook. Then learn the handful of pairs that come up constantly in IELTS topics: behaviour/behavior, labour/labor, programme/program, travelled/traveled, analyse/analyze, defence/defense. Our complete guide to British and American spelling has the full set in one place.
Drill. After every practice essay, spend one minute scanning only for those pairs. Nothing else. Within a few weeks the scan finds nothing.
Mistake 3: Losing Listening marks on easy nouns
This is the most painful mistake on the list. You hear "the price includes accommodation", you know the answer, and you write accomodation. Understood perfectly, marked wrong.
The words that do this are nearly always ordinary nouns from forms, bookings, timetables and maps: accommodation, library, Wednesday, February, restaurant, equipment, environment, schedule, souvenir, questionnaire. Because they feel easy, candidates never practice them, and because they look familiar, the error survives the final check.
Each one has a single trap. Accommodation has two c's and two m's. Library has an r after the b that many speakers swallow. Wednesday keeps a d that nobody pronounces. Find the trap, name it out loud, and the word becomes safe. For the full picture of how Listening answers are marked, including word limits and plurals, see how one wrong letter costs you the mark in IELTS Listening.
Drill. Ask someone to read you ten of these words, or use a recording, and write each one as you would on the answer sheet. Check immediately. For every miss, write only the tricky part twice, then the whole word once. Hearing and then writing is the skill the test uses, so it is the skill to practice.
Mistake 4: Dropping or adding double letters
Sucess, adress, recomend, begining, ocured, comittee. Double letters cause more IELTS spelling errors than almost any other single pattern, and they are especially likely at speed.
Some doubles follow a reliable rule. When a verb ends in one vowel plus one consonant and the final syllable is stressed, you double before adding -ing or -ed: begin, beginning; occur, occurred; prefer, preferred. When the stress falls earlier, you usually do not: visit, visited; develop, developed. British spelling doubles a final l regardless of stress, which is why travelled and cancelled are British while traveled and canceled are American.
Other doubles come from prefixes. Accommodate, address, occur and commit all carry an old Latin prefix whose last letter was absorbed by the consonant after it. You do not need the history, only the habit of noticing that these words start with a doubled letter.
Drill. Learn doubles in families rather than alone: success, successful, successfully; occur, occurred, occurrence; recommend, recommended, recommendation. Write each family from memory, then check.
Mistake 5: Guessing the "shun" ending
Educasion, decission, discusion, politicion. The ending sounds the same in all of these, so sound alone cannot tell you which spelling to use. The word it comes from usually can.
A verb ending in -ate or -ct takes -tion: educate, education; protect, protection. A verb ending in d or de takes -sion: decide, decision; extend, extension. A verb ending in ss takes -ssion: discuss, discussion. A verb ending in mit also takes -ssion: permit, permission; admit, admission. And a person whose job comes from a word ending in -ic takes -cian: music, musician; politics, politician; electric, electrician.
There are exceptions, but these defaults are right far more often than a guess. Our guide to tion, sion and cian goes further.
Drill. Make a two-column table with ten verbs on the left and the nouns covered on the right. Fill in the nouns from memory, check, and write a Task 2 sentence using three of them.
Mistake 6: Numbers, dates and prices in Listening
Many Listening answers are data: a phone number, a price, a date, a time, a postcode. Candidates hear correctly and still lose the mark, for two reasons.
The first is a listening problem that looks like a spelling problem. Thirteen and thirty, fifteen and fifty sound close in fast speech. The clue is stress: the teen numbers are stressed at the end (thir-TEEN) and the tens at the start (THIR-ty).
The second is spelling proper. If you write numbers in words, forty has no u, ninth has no e, and twelfth keeps its f. The safest habit is to write numbers as digits wherever the instructions allow, which avoids those traps completely. For dates, choose one clear, standard form, such as 23 March, and use it every time. February and Wednesday are two of the most misspelled words on any Listening paper.
Our guide to spelling numbers, dates and addresses covers the whole category, including the letter names that trip people up when a speaker spells out a surname.
Drill. Once a week, have someone read you ten short lines full of dates, prices and phone numbers. Write only the answers, exactly as you would on the sheet, then check every character.
Mistake 7: Copying from the Reading passage carelessly
In many Reading question types, the answer is printed in the passage and you copy it. People still lose marks, by writing enviroment when the text says environment, dropping a plural s, or adding a word that breaks the limit.
This happens because the eye moves faster than the hand. You recognize the word, assume you know it, and write your own version instead of the one on the page.
Turn copying into a deliberate two-step. First, put your pen tip under the exact phrase and copy it letter by letter. Then compare your answer with the passage and ask three questions: is a letter missing, has a plural changed, is any word over the limit? Hyphenated words such as check-in count as one word under the official rules. The whole check takes a few seconds per answer.
Drill. Take a short passage, write ten gap-fill questions for yourself, and answer them in five minutes. Then compare letter by letter. Most people are surprised by how many slips they find the first time.
Mistake 8: Reaching for words you cannot spell
Many candidates have heard that band 7 requires "advanced vocabulary", so they fill their essays with ubiquitous, detrimental and exacerbate, and misspell half of them. The descriptors describe exactly this candidate at band 6: "If the writer is a risk-taker, there will be a wider range of vocabulary used but higher degrees of inaccuracy or inappropriacy."
What band 7 asks for is "some ability to use less common and/or idiomatic items" and "an awareness of style and collocation". Natural, precise phrases such as a significant impact on, widely available or reduce traffic congestion do that job, and you can spell them.
Build a trusted word bank. A word earns its place only when you can spell it correctly from memory on three separate days. Until then, keep practicing it, but use a safer word in your essays. The most useful words to add come from the Academic Word List, because they turn up in every topic.
Drill. Take an old essay, circle every word you misspelled or hesitated over, and rewrite each sentence with a word you are sure of. Then add the circled words to your practice list, not your essay list.
Mistake 9: Keeping no record of your own errors
Look back over a month of practice and you will usually find the same ten or twenty words wrong again and again. The problem is not that you do not know them. It is that every correction was a one-off: you saw the right version, thought "I must remember that", and moved on.
Keep an error log. A notebook, a spreadsheet or a note on your phone is enough. For each word, write the correct spelling, the version you wrote, and the trap in a few words ("two m's", "no e after p"). After every practice test, add the three to ten most important misses.
A log turns a vague sense of being bad at spelling into a short, specific list. That list is worth more than any published list of words candidates misspell, because it is yours.
Drill. Five minutes after each practice test: collect the errors, name each trap, write each word correctly once, and schedule a review for tomorrow and for next week.
Mistake 10: Cramming the week before
The last-week cram feels productive. You copy the same fifty words again and again the night before the test, and on the day you still write enviroment.
Memory research explains why. Practice spread across days beats the same amount of practice in one sitting; Cepeda, Pashler and colleagues reviewed hundreds of experiments in 2006 and found the effect again and again. Trying to recall a word also beats looking at it again. In Roediger and Karpicke's 2006 study, students who tested themselves remembered much more a week later than students who simply reread. Cramming uses neither advantage.
The fix is ten minutes a day, starting as early as you can. Review a few words from your log, write each from memory, check, and correct. Tools that schedule the reviews for you make this easier. Spelling.School is one: you hear each word, type it, see exactly which letters went wrong, and the word comes back for review with spaced repetition.
A two-week plan
If your test is close, this plan puts the drills in order. It takes about fifteen minutes a day on top of your normal preparation.
In the first week, work on Writing. On day one, make your list of topic words and do the Mistake 1 drill. On day two, choose British or American and write your list of pairs. On day three, do the double-letter families; on day four, the "shun" table. On day five, go through old essays and start your error log. On day six, rewrite one old essay with safer vocabulary. On day seven, write a timed Task 2 with spell-check off and count your spelling errors.
In the second week, work on Listening and Reading. Days eight and nine are dictation, first of easy nouns and then of numbers and dates. Day ten is careful copying from a Reading passage. Days eleven and twelve are full practice sections followed by the five-minute log routine. Day thirteen is a full timed rehearsal. On day fourteen, compare today's essay with day seven's and see which errors have gone.
Every day, begin with a five-minute review of your log. That is the part that makes the rest stick.
What to do next
Start the error log today. Go through your last two practice essays and your last Listening test, write down every misspelled word with its trap, and review that list for ten minutes tomorrow. If you want a wider view of where your weak spots are, try this twenty-minute self-audit.
If you would rather have the scheduling done for you, Spelling.School's short adaptive warm-up and 14-day trial of everything are a simple place to begin, and the pricing page shows what the free plan includes. Either way, the work is the same: a small number of words, recalled from memory, a little every day.
Questions people ask
Will one or two spelling mistakes lower my IELTS Writing band?
Usually not. The public band descriptors allow "only a few errors in spelling and/or word formation" at band 7, as long as they do not detract from overall clarity, and occasional errors even at band 8. What pulls a score down is a pattern: the same common word misspelled several times, or errors frequent enough that the reader keeps noticing them.
Does IELTS accept American spelling?
Yes. IELTS accepts both British and American spelling in Listening, Reading and Writing, wherever you take the test. The safe habit is to use one system consistently, for example always organize and color, or always organise and colour. Choose the one you already know best rather than switching shortly before the test.
Is a misspelled answer in IELTS Listening marked wrong?
Yes. Listening and Reading answers are marked against a key, and a misspelled word does not match it, even if you clearly understood the recording. Each correct answer is worth one mark out of 40, so a few spelling errors can move your band by half a point. Plurals and word limits are marked just as strictly.
Can I write my IELTS Listening and Reading answers in capital letters?
Yes, capital letters are accepted, and many candidates find them easier to read on a paper answer sheet. If you use capitals, write the whole answer in capitals so that nothing is ambiguous. Writing in capitals does not change the spelling rules, so every letter still has to be right.
Is there a spell-checker in computer-delivered IELTS?
No. The computer-delivered test has no spell-checker or autocorrect, so you have to catch your own errors exactly as you would on paper. It is worth writing your practice essays with spell-check turned off, so that you find out which words you really get wrong.
Does spelling count in IELTS Speaking?
No. The Speaking test is assessed only on what the examiner hears: fluency and coherence, vocabulary, grammar and pronunciation. Spelling never comes into it. Learning a word's spelling and pronunciation together still helps, because it tends to make both more accurate.
How long does it take to fix IELTS spelling mistakes?
For a short list of your own problem words, a few weeks of daily practice is usually enough to make them reliable. Ten minutes a day, spread across several weeks, works far better than a long session the week before the test. Start with the words that appear most often in your own practice essays and Listening answers.
