Setting

The study took place in 12 early colleges, which are schools located on college campuses that combine high school and college experiences. These schools were located in urban and rural settings in North Carolina.

Study sample

The researchers randomly assigned 952 students to the intervention group and 735 students to the comparison group. A total of 1,687 students who applied to an early college high school in grade 9 were included in the study, with smaller sample sizes for some outcome measures. Approximately 41% were male, 3% had a disability or impairment. Sixty percent of students were White, 27% were Black, 3% reported two or more races, 1% were Asian, 1% were American Indian or Alaska Native, and 8% reported another race or did not report their race. Eight percent were Hispanic or Latino. Forty-one percent of the students were the first in their family to go to college. The percentage of students who were eligible for free and reduced price lunch were not reported.

Intervention Group

Students in the intervention group were offered admission to one of 12 early college high schools located on college campuses. The goal of the early college high school program is to prepare high school students for college. The program focuses on students who are underrepresented in college, such as low-income students or those who are the first in their family to go to college. Students can earn a high school diploma and receive college credit over the course of a four- to five-year program. The program prepares students academically by offering honor-level college preparatory high school curricula and opportunities to enroll in college courses at the partner college starting in 9th grade. Early college high schools are designed to teach students critical thinking, extensive writing, cooperative work, and ongoing class discussion skills, as well as other skills to prepare for college. Early college high schools also support students to navigate the college admissions process. In addition, students are provided coaching through the college application and enrollment process, including applying for financial aid. In this study, 92% of students who were offered admission to an early college high school attended the school.

Comparison Group

Students in the comparison group attended other non-early college high schools as usual. These students applied to an early college high school but were not selected by lottery to attend the program.

Support for implementation

The authors do not provide details about support for implementation of the early college high school program.

Setting

This study took place in North Carolina among 12 early college programs located in urban and rural settings.

Study sample

The analytic sample included 952 students in the intervention group and 735 in the comparison group. These 1,687 students applied to 12 early college programs between the 2005-06 school year and the 2008-09 school year. About 51% of students were eligible for free or reduced-price lunch, and 3% had a disability. Sixty percent identified as White, 27% as Black, and 9% as Hispanic or Latino. Less than half were male (41%). The average age was 15.4 years at the time of the lottery.

Intervention Group

Students in the intervention group were offered admission to one of 12 early college programs in North Carolina. Early college programs combine elements of high school and college, offering students an opportunity to earn both a high school diploma and receive college credit over the course of a 4 to 5-year program. These programs are offered as small schools located on college campuses, primarily in community college settings. As students progress in early college, they gradually take more courses for college credit while also fulfilling high school graduation requirements. During their experience, students may earn enough college credit to receive an Associate's degree or complete the first 2 years of a 4-year degree program. In addition to more challenging academics, early college programs teach skills pertaining to good study habits and time management to help students successfully navigate college.

Comparison Group

Students in the comparison condition applied to an early college program but were not selected by lottery to attend the program. These students received business-as-usual high school education, which most likely would have been enrollment at a traditional high school in their school district.

Support for implementation

The authors do not describe additional details about implementation of the early college program.
