2. There is a two-week grace period, per UIL, for incompletes. Not for failing grades. If you had a kid fail, they're out after 6 weeks + grace. If they had an I, they have two weeks to get the work in - again, provided your district adopted that policy.
In my district, the six weeks date, grade check, and lose/regain dates are unchanged from before the UIL ruling. We are not going with a two week grace here, which really stinks - my already tiny band is going to be down to barely a dozen players by tomorrow if they don't get their acts together. Luckily my district ruled that no one's failing (since we're on a 9 weeks grading cycle) - you either have a passing grade or an incomplete, but then they didn't accept the two week grace period.. argh.
