This discussion guide is part of a larger practice guide designed to help state education agencies (SEAs) define measurement goals, select college and career readiness measures and indicators designed to support those goals, and use the data gathered with those measures and indicators to make informed decisions about college and career readiness policies, programs, and interventions. The chapter 1 discussion guide focuses on setting the stage for the rest of the guide by defining the measurement landscape and exploring the SEA role in measurement goals related to college and career readiness and success.
