This report provides a portrait of dual-credit participation rates and trends between the 2011-12 and 2014-15 school years. Dual-credit participation by demographic characteristics such as race/ethnicity, gender, and socioeconomic status is explored throughout each of the five briefs contained within this report. Each report brief also includes questions to consider--which promote a deeper exploration of the data--as well as next steps that can help educators and stakeholders overcome barriers to expanding dual credit. The report briefs can be read individually or together as a longer report with five content sections. The five briefs address the following questions: Who participated in dual-credit courses? What were the characteristics of districts with students who participated in dual-credit courses? In which dual-credit course competency areas were districts most likely to have participated? What were the pass rates of students who participated in dual-credit courses? To what degree did the state meet its goal of 30 percent?
