So much documentation to get to Korea.  It just seems like an endless supply of records, tests, confirmations, etc, etc, etc...
On top of it all, getting documents stamped or certified just adds more layers of "stuff" you need to do to get to Korea.

Apostilles are a way to certify the authenticity of foreign documentation.  You will need to get an apostille for diplomas and criminal record checks (CRC) so you can receive your visa to teach in South Korea.

Someone who was watching one of my videos asked me about the process for getting an apostille for your college diploma.  It would've been helpful for me when I was applying to have a video to reference.  So, I decided to make a short clip about the process (while desk warming during mid-terms).
I hope it's helpful.
