Teacher Certification online through Teach Now

Hello,

I work at an international school in Thailand and my husband, who has a degree in Art, would like to get teacher certified. "Teach Now" was recommended to us as a fully online school that awards teacher certification in Washington, D.C., but I am concerned about how it is viewed by international schools, specifically in Europe. Has anyone earned teacher certification from this school and, if so, have you had problems gaining employment?

Please help.

I didn't find the right solution from the Internet.
