Dzeytoun:
 >>Lots  of people opine that Snape gets good results in terms 
of his  students' performance.  I think this is largely speculation.  
I did  an admittedly fast review of canon last night and could find 
no  references in which it was indicated that Snape got good 
performance  out of his students, that they generally did well on 
OWLS, that  people regarded him as making students learn, etc.  
All the  references I could find - and I may well have missed 
some - speak to  his own personal expertise at potions, NOT to 
how much his students  learn, etc. <<

OOP ch 12 US 252

"...I advise all of you to concentrate your efforts upon maintaining 
the high-pass level I have come to expect from my O.W.L. 
students." 

Oblique confirmation that Snape's expectations are not 
unjustified comes from Tonks and McGonagall. Tonks had a 
hard time qualifiying as an Auror  --evidently despite Snape's 
strictness about admission to NEWT potions, there's no 
shortage of candidates and the Auror office can afford to be 
selective. They haven't taken anyone on in the last three years, 
McGonagall says, so they must be fully staffed.
