Is this TESOL course accredited by the nation of Taiwan?

I don't know. Technically, TESOL is internationally accredited, but I do not know if it is in Taiwan. Sorry to be so little help.. 🙁

Yes it is fully accredited internationally. It depends on the school but usually all 120 hours tesol certificates are accepted by most schools or training centers around the world. Some schools and training centers might ask extra certification though.

I am not sure about Taiwan but as far as I know the course is accredited worldwide.

The TESOL program is accredited and accepted worldwide but schools may be particular about what they accept.

Southeast Asia seems to prefer a CELTA or TESOL Trinity so you may want to investigate before applying.

Actually, I've never even needed it when applying for a job here in Taiwan. Although, whoever saw
my resume may have thought it is worth something. So, yes, they will appreciate the certificate in Taiwan,
but I've never seen where it is absolutely necessary to have.

I originally took the online course before I went to work in China.
