I need to take a TEFL online course- basically to be able to show something.
I am teaching now for a while and business is growing.

After a lot of research, i am still not able to figure out WHICH accreditation really means/ensures anything :

ACTDEC
ASDEC
ASET
ODLQC
OCNW.....
I do understand that those courses are nothing like CELTA or Trinity,but i have no choice so i want to make sure that i will atleast take one of the "better" courses.
I would appriciate some help..in the form of a clear- yes worthwhile or not..

Thanks a million
