Common waiver component for several Kansas districts.

Common Core & Smarter Balance emphasis on college/career readiness.

Availability of College Readiness Benchmarks in ACT series assessments.

Scaled scores in each subject area demonstrated to be associated with a 50% chance of getting a “B” or higher, or a 75% chance of getting a “C” or higher, in a credit-bearing freshman college course.

How do these benchmarks compare with KCA performance?
