senior class size = how good a sorority is?

I understand where you're coming from, and I used to think that as well. But the truth is, there's lots of reasons girls drop out other than not liking the sorority or it being a bad sisterhood. Financial is the biggest one. But sometimes other priorities become more important. Or maybe they just aren't into the sorority life as they were when they were freshmen. It happens. I don't think it should reflect badly on a house when a senior class is small.

Now, if we're looking at a house who consistently takes huge pledge classes and has TINY TINY senior classes, then it might be fair to wonder why girls are dropping. But then again, that senior class is about to graduate and the rest of the classes might be a lot different.

So to sum up, no, overall it is not fair to judge a house by the size of their senior class. Each pledge class varies way too much for that to be fair.

Women are sorority members for life, even when they become less active collegians. I agree with post #1, there are many reasons for decreasing individual sorority activity. Taking a semester abroad may widen your personal horizons to the extent that you mature beyond normal collegiate sorority interaction and functions, causing you to ask for sorority alum status.

It is also wise to determine for comparison, thru UA's administrative offices, how many freshmen students actually graduate in 4-5 years. It could be fraternities/sororities have a larger percentage of freshmen new members graduate than the percentage of freshmen the school graduates.

Losing students is one risk a university automatically accounts for when they make their yearly budgets and hire staff.

is there any way to actually tell how many seniors graduate as active sorority members? Some may not post graduation pictures in their letters or talk about their experience as a member on social media or w/e but still are members. I'm not sure if there's any real way to judge how large a graduating class in a sorority is

That pretty much mirrors the overall drop out and transfer rate of college students at large universities from their freshman til senior years. If you tracked all the people who were in your dorm freshman year for the next three years then you'd find pretty similar percentages.
