Hello, Doan.
Thanks for reaching us through Microsoft Community.
We understand that you want to visualize and download your MOS: Word Certification on Your Dashboard.
Keep in mind that Certificates are available for all Certifications in Your Dashboard except for Microsoft Office Specialist (MOS) and Microsoft Technology Associate (MTA), which should be visualized and downloaded directly from your Exam Provider's site, in this case on Certiport.
If you are having issues visualizing and downloading Certificates from Certiport's site, we recommend you to contact Certiport Costumer Service here.
In the meantime, to provide you with an alternative solution, we have sent you a copy of your Transcript where you can visualize your Exams and Certifications records.
Please let us know if you have any other questions, or if the assistance given solved your request, please indicate “Yes” to the question “Did this solve your issue?” shown below, so other Learners can benefit from this. Your feedback is important to improve our service. In case we do not receive a response, the thread will be concluded within two business days.
Wishing you the best,
