Three questions about future assessments

Since we believe students need to reach the standards for eleventh and twelfth,  do we need to plan  on assessing literacy and mathematics  in those years?

Since we're also planning a board exam that can identify tenth graders as ready for college, will that exam test for ability to work at the twelfth grade level?

Since the whole point is to equip students for success in college and career, how will we close the loop and check that our assessment results really do correlate with success in those two arenas?

I'm confident there's hard work underway on all those issues, and I don't expect all the answers to be ripe for sharing yet.  Still, I'm noticing that working consistently for readiness is going to come with lots of challenges beyond drafting and adopting the standards.
