欧洲共同语言参考标准（The Common European Framework of Reference for Languages，简称CEFR）是被国际认可的描述语言能力和水平的标准。在欧洲，CEFR被广泛接受，并且越来越多的运用到欧洲以外的世界范围内。EF SET英语测试是现在世界上唯一一套针对所有CEFR英语水平等级（从A1到C2六个级别）设计的试题，可以精确判断出测试者的英文能力属于哪个CEFR级别。托福和雅思一般只能判断B2及以上，而不是所有的英语程度。

The Common European Framework of Reference for Languages (CEF or CEFR) was put together by the Council of Europe as a way of standardising the levels of language exams in different regions. It is very widely used internationally and all important exams are mapped to the CEFR.
