Actually, first of all it was 8 students with an O, two with an E.
This is out of a class that JKR tells us included approximately 140
students, not 40. Since all the Hogwarts students had to take
Potions in fifth year, that means, if we allow twice as many Es as
Os and twice as many As as Es (which is a reasonable estimate, at
least at the schools where I've taught), that 54 students, or only
slightly more than a third, even passed the OWL.
This I think pretty much definitively ends the discussion of whether
Snape is a good teacher. He is a miserable, poor, absolute failure
as a potions teacher, hands down, end of discussion.

Lisa responds:
The problem I have with this is that it paints Dumbledore a fool. If Snape 
has been teaching at Hogwarts for, what, 16 years now, and has been such a 
horrible teacher, why would Dumbledore have kept him around? Why would the 
Board stand for it?
