In calculation student attrition, what should be in the "relative attrition — personal" column of the attrition table (Table B)

Q:  Is the relative attrition personal column meant to capture anyone who won't graduate with their class for any reason other than academic? For example, does this include those in a PhD program, or just those who left for a truly personal reason like a change in career goals?

A:  This includes just those who left for a personal reason.
