在CRS打分中，教育中的本科、硕士、博士等打分，很容易理处理，但有一个双学历的分数，Two or more certificates, diplomas, or degrees. One must be for a program of three or more years，很多人不确定是不是适合自己。

下面是对这个问题的澄清：

Certificate是结业证，Diploma是文凭，Degree是学位证书。两个证书都需要通过ECA认证。两个学历证书，其中一个至少是3年制及以上的学习获得的。

另外一个证书，必须是高中后的教育，可以是下面其中的任何一个： 

• Post-Bachelor's Certificate
• Post-undergraduate certificate
• Post-Bachelor's Diploma
• Post-undergraduate diploma
• Graduate Certificate
• Graduate Certificate with a focus in [area of concentration]
• Postgraduate certificate
• Postgraduate Diploma
• Graduate Diploma with a focus in [area of concentration]
• Graduate diploma
• two-year Postgraduate Diploma, specializing in [name of discipline]
• two-year Bachelor’s after degree with a focus in [area of concentration]
• one-year Postgraduate Certificate in [name of discipline]
• Dual Bachelor’s degree (four years) 4年制的双学士
