A funeral is covered under bereavement and would not be counted as a call-out for HR purposes.
Generally speaking, attendance is lumped under performance, and it's difficult to term someone who has issues with attendance only. If it's school which is causing you to have these issues, Target does offer something called intermittent leave, which basically means you can take off when you need to for a specified reason as long as you have documentation. IE: you set up intermittent leave for school, and if you need to call off just get your professor to write you up a note and you give that to your HR, and fax it to hewitt, and you're good to go. Abusing this will get you fired, but if you legitimately have school commitments which cannot be predicted, this is probably the best route for you to go.
