An international English certificate proves your level to universities, employers and immigration authorities. But with so many exams available, which one should you take? Here's a simple guide.

IELTS

IELTS tests listening, reading, writing and speaking, and gives you a band score from 1 to 9. IELTS Academic is widely used for university applications; IELTS General Training is often used for work and migration. Results are generally accepted for two years.

Cambridge English

Cambridge English Qualifications are level-based exams, such as B2 First, C1 Advanced and C2 Proficiency. They show your level on the CEFR scale and the certificate does not expire. They are popular with employers, schools and many universities, especially in Europe.

TOEFL

TOEFL iBT is an academic English test that is widely accepted by universities, particularly in North America. It tests all four skills and is taken on a computer.

Trinity College London

Trinity exams, such as the GESE (spoken English) and ISE (integrated skills) qualifications, are popular in many countries and assess practical communication skills.
