This brief report offers analysis of ACT and SAT results from 2008 to 2013 in the Southern Regional Education Board (SREB) region. The brief focuses on the increase in test participation rates and points to policies that SREB states initiated that affected these rates. Five SREB states currently require 100 percent student participation on the ACT. Others include ACT results as part of their school accountability system. This report will explore these changes in SREB state policies and the effects they have on participation and scores in these states. In addition, it will inform policy-makers on how other SREB states use college admission testing. The following are appended: (1) Attainment of College and Career Readiness On the ACT College Readiness Benchmarks, 2013; and (2) Achievement Gaps on the ACT and SAT by Race and Ethnicity, 2008 to 2013.
