加拿大的学历认证必须由cdgdc直接寄给wes吗

如题~~急求各位,我先在CDGDC做了学历证书和成绩单的认证和翻译,然后报告寄给了自己。但发现在WES的网站上有下面一段话,是不是必须让CDGDC把认证结果直接寄给WES才算数呢??多谢!

Arrange for your degree certificate to be verified and sent directly to WES by the following Ministry of Education-designated verification agency
China Academic Degrees and Graduate Education Development Center (CDGDC)

对,是必须的,做WES认证,学位和成绩单的清华认证报告是需要直接寄给WES的。
