pref night rushee # (which may or may not take into account drop outs after the pref parties) divided by #of chapters = quota
Pref invite #s depends on your retention rate. The retention rate is the chapter's avg retention for pref night for the last three years. (This equation is used for every night.)
quota/retention rate= #of girls invited to pref
This is where I have to point out that quota fluctuates until this night.
So as an example:
The night before pref all the chapters are sitting down to make pref invite lists. A total of 200 rushees are left. There are 5 chapters.
quota
200/5=40
Sorority A has a retention rate of 90%. They're the house everyone wants to be in.
40/.90=44.4444 let's just call it 45
So Soroity A can invite 45 girls to pref.
Sorority B has a retention of 60%.
40/.60=66.6666 We'll call it 67
Soroity B can invite 67 girls to pref.
And so on and so on.
But this is where the whole quota may or may not take into account post pref drop outs becomes a problem.
If after pref 50 girls drop out of rush that would make quota = 30. Now considering Sorority A's retention ratio is so high; what are the chances that they are gonna lose 15 rushees? Pretty darn slim! So then you get Sorority A with a massive rush class compared to the rest of the chapters. And it makes the rest of the chapters look weak. If Sorority a has 40 rushees the avg pledge class for the four other chapters will be 27. So
Sorority A's class is 50% BIGGER than Sorority B-E
The way it's supposed to work!
