In the absence of any supporting context (which might have been helpful here, by the way ) I would take it to mean a letter certifying that a student has successfully completed his or her English course, yes.
What will be said in that letter (I assume) is going to be like .... This is to certify that Baby_V has been studying English for one semester at ...... (Language School's name), given on (date).
I don't know exactly what will be said in that letter as I'm asking the school to issue the letter for me to apply for a program. It will be like evidence to guarantee that I have really been studying English.
I see now
I'd be inclined to call that a certificate: the wording is much the same as appears on the certificates I get every year from the university for my Italian course. Although it may not have gold-plated writing and an official seal, the purpose is the same - it certifies officially that you completed the course as stated.
I assume your Italian must be very good! Hahaha. Thanks, DonnyB.
I didn't know English native speakers would call it "certificate" as it is just a paper without an official seal. However, I totally agree with you that the wording is much the same as appears on certificates.
Let's finish this thread up (just to confirm that we are on the same page ), is it what we call "English course certificate"?
