IELTS (International English Language Testing System) is one of the most widely recognized and used English language tests worldwide. By taking the IELTS exam, candidates can obtain an internationally recognized language proficiency certificate, demonstrating their basic communication skills required for studying, working, and living in an English-speaking environment. So, what level of proficiency is needed to obtain an IELTS certificate?

Firstly, the IELTS exam consists of four sections: Listening, Reading, Writing, and Speaking. Each section is scored from 0 to 9, with a total score of 36. To obtain an IELTS certificate, candidates need to achieve a minimum overall band score of 6.5, with no score lower than 6 in each section.

对于不同的学术或移民目的，考生需要达到不同的成绩要求。一般来说，大学本科和研究生课程对雅思成绩的要求较高，常常需要达到总分7分或以上。移民申请方面，各国的要求也不尽相同。有些国家可能要求总分6分，而有些国家则要求总分7分以上。

Different academic or immigration purposes have different score requirements. Generally, undergraduate and postgraduate programs have higher IELTS score requirements, often requiring an overall band score of 7 or above. Regarding immigration applications, requirements vary from country to country. Some countries may require a total band score of 6, while others may require a total band score of 7 or higher.

雅思证书的获得对考生具备一定的英语能力至关重要。在准备雅思考试时，考生可以参加培训班、自主学习或使用在线资源来提高听说读写等各项技能。此外，多做模拟试题和参加模拟考试也是提高考试技巧和熟悉考试流程的有效方法。

Obtaining an IELTS certificate is crucial for candidates to demonstrate their English language proficiency. When preparing for the IELTS exam, candidates can join training courses, study independently, or use online resources to improve their listening, speaking, reading, and writing skills. Additionally, practicing with sample test questions and participating in mock exams are effective ways to enhance exam skills and become familiar with the test format.

值得一提的是，雅思证书的有效期为两年。如果过了两年没有再次参加雅思考试并获得新的成绩，原有的雅思成绩将失效。因此，对于那些计划在未来几年内使用雅思证书的考生，定期参加考试以保持成绩的有效性非常重要。

In English:

It is worth mentioning that an IELTS certificate is valid for two years. If more than two years have passed without retaking the IELTS exam and obtaining a new score, the previous IELTS score will expire. Therefore, it is essential for candidates who plan to use their IELTS certificate in the coming years to regularly take the exam to maintain the validity of their scores.

总之，雅思考试是世界各地许多学术和移民机构广泛接受的英语语言测试。通过取得一定的分数，考生可以获得国际认可的雅思证书，进而证明自己具备适应英语环境的基本沟通能力。对于那些希望出国留学、工作或移民的人来说，雅思证书无疑是提高竞争力和实现目标的关键。
