certified是指公证还是鉴定的意思？急！！！

6. if you were conditionally admitted to a study programme: a certified
copy of the document(s) required to fulfil your admission conditions e.g.
a certified copy of a degree/test result (if you have not already submitted
this);
学校行前准备中的一句，那certified是指公证的意思吗？还是指的是只要被有关机构（如学校）鉴定过就可以？大家帮帮忙，如果是要公证的话我就得抓紧了~~

刚收到学校的回复，说只要学校盖章的翻译件就行，楼主可以把帖子删了，谢谢
