CAE / CPE

Among Cambridge English Qualifications, C1 Advanced (formerly CAE) and C2 Proficiency (formerly CPE) are academic English certificates for advanced learners. They are accepted by many universities and employers in the UK and Europe, and the results are valid for life (unlike IELTS or TOEFL, which expire after two years). The exams use the Cambridge English Scale (approximately 160–230), corresponding to CEFR levels C1/C2. For Chinese test takers, these certificates are like a one-time 'English proficiency stamp': high difficulty, long preparation time, but once you achieve C1/C2, the result is permanently valid and highly regarded. They suit students with a solid English foundation who plan to study or work in Europe long-term and want a score that never expires. Note that some US institutions and immigration programs do not directly accept them, so always verify before applying.
