雅思新手须知雅思成果单及寄送留意事项

雅思成果单长什么样?

现在的雅思成果单上标注有雅思索试类型，雅思索试中心代码，考试时间，考生准考证号以及考生的个人信息，听说读写及综合雅思成果，最终会有雅思官方的印章，及签名。需要留意的是，在成果后有一个CEFRlevel,关于CEFR，全称是CommonEuropeanFrameworkofReference.CEFR的打分方式有A1,A2,B1,B2,C1,C2.CEFR和IELTS的之间有一个相对的分数参照：

欧洲共同语言参考标准(CEFR)是被国际认可的描述语言力量和水平的标准。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。雅思和CEFRlevel的对比参照如上，雅思索试的内容和评分标准并没有由于CEFRLevel而转变。所以大家完全不用担忧，只需正常的备考即可。CEFRlevel只是不同考试之间的一种转换中介。对于烤鸭们本身的备考并没有任何的影响。无论是入学，还是签证，都还是以单项成果和总成果为主，和以往的用法都全都。
