letter of experience
i am not a teacher
which is correct to write
this is to certify that Mrs. ..............
has worked with us as english teacher or worked as English teacher during the period May 1,2008 to ................
First of all, i'm not a teacher (so excuse me if I'm making a mistake), but i love English.... so let's see...
I'd say: "This is to certify that Mrs. ..... has worked with us as AN English teacher during the period MAY 2008 onwards"
"This is to certify that Mrs. ...... has worked IN OUR ORGANIZATION/UNIVERSITY/SCHOOL as AN English teacher during the period MAY 2008-MAY 2009" (for example) "to" is OK too.
I'm looking for some language partners to improve our skills together talking by skype, my name there is blancogini, i'll be waiting for your call !
