or OET.
I will make the comparisons here and then you can decide.
- IELTS is recognized all over the world to gain entry into any institute or profession in an english speaking country.Students as well as professionals can take this test.OET is recognized only in Australia/Newzealand and is a test only for medical practitioners.
- The exam registration fees is five times cheaper for IELTS than OET.
- Both IELTS and OET test 4 skills in English--Reading,Writing,Listening,Speaking.Candidates are marked in each of these skills.The IELTS test is conducted at 2 levels--Academic and General--theAcademic level,is slightly more difficult than the General level.IELTS candidates receive scores from a bandwidth of 1-9 with 1 being the lowest level of proficiency.OET candidates receive their evaluation in the form of grades from A-E with E being the lowest level of proficiency.
- IELTS test papers are on gneral topics and require good knowledge of English grammar and vocabulary.In OET, the Reading and Listening tests are health related and the writing and speaking test are profession related.That is , dentists will get dentistry related topics,physiotherapists will get physiotherapy topics,etc.Here too, grammar,syntax and spellings are evaluated.
- The IELTS writing test has two parts to it--an essay and analysis of some given statistical data.The OET writing test asks the candidate to write a referral letter of 200 words,related to the diagnosis of a patient's problems.This ,as I mentioned earlier is profession related.
- The speaking test in IELTS is a conversation between neutral person and the candidate.Later, the candidate has to speak for at leat 5 minutes on a particular topic.In OET the candidate will have to play the role of a doctor and speak and diagnose a patient's problems.The patient's role will be played by someone neutral.The speaking test in both IELTS and OET will be recorded and later evaluated by two examiners.
- If a candidate fails in even one section of the IELTS and does not get the required average to pass,he/she will have to re-register and retake the entire test,ie all the skills.In the OET however,the candidate has to retake a test only in the skill where he/she has failed.
- Medical professionals and students require a bandwidth of 7 in the General category as average in IELTS in any country.Most Australian and New Zealand Medical Councils accept a B grade average in the OET.
Check the accepted scores in any Institute/country before you prepare for the test.If you are not proficient in English take adequate coaching before you appear for the test
