Start with the organisation that asked for it
The right English test is the one accepted by the university, employer or immigration authority you are applying to. IELTS, TOEFL and Cambridge English qualifications are all widely recognised, but requirements differ, so check the organisation's current list of accepted tests and minimum scores before you book anything.
How the main tests differ
IELTS comes in Academic and General Training versions, with the academic form usually needed for study. TOEFL iBT is aimed mainly at academic settings and is widely used by universities in North America. Cambridge English qualifications, such as B2 First and C1 Advanced, target a specific level and do not expire, though some organisations still ask for recent results.
Understanding levels
Many requirements refer to the Common European Framework of Reference for Languages, which runs from A1 for beginners to C2 for highly proficient users. Knowing your approximate level helps you judge which test and target score are realistic.
Practical factors to compare
Look at test centre availability near you, whether a computer-based or at-home option is offered, the cost, and how quickly results arrive. Some candidates prefer a face-to-face speaking test with an examiner, while others are comfortable speaking into a microphone. Also note how long results stay valid for your purpose.
Preparing once you have chosen
Each test has its own task types and timing, so practise with official sample materials for your chosen exam. A tutor who knows the format can identify weak skills, set timed practice and give feedback on writing and speaking, which are the hardest areas to assess on your own.
