Ideas for a points plan?? HELP!!

[victoriana]

My chapter uses a points system, and it has been very successful in helping our chapter grow on campus. If a sister falls below 80% attendance for required events, she is put in poor standing. The only things that people can get excused for are emergencies, class and sometimes work/medical appointments. Required events include weekly meetings, occasionally Panhellenic meetings, philanthropy events, recruitment events, rituals, and new member events. It sounds like a lot, but it's typically no more than 2 events per week. We can't include socials or anything we have to pay for as mandatory, but we do our best to encourage attendance at non-required events by making them as fun as possible!
