Characteristics of study sample as reported by study author.
The study was implemented at rural and suburban high schools in the Carroll County and Haralson County school districts, Georgia. Students in the intervention group had daily access to learning activities in the 12 for Life manufacturing facility. All treatment students were enrolled in Carroll County schools and comparison students were enrolled in both Carrol and Haralson County schools. Carroll County Schools has a history of low graduation rates (67.5%), high dropout rates (4.8%), and a high percentage of students who are economically disadvantaged (61%).
All students served were economically disadvantaged, according to a researcher-developed rubric defining financial need. 50% of the high school students in the sample were supporting themselves, responsible for costs of food and shelter with little or no support from parents or guardians.
The i3-funded intervention, 12 for Life, was developed in conjunction with Carroll County School District as a new approach to applied, work-based learning. The 12 for Life program is designed to provide very high-need students with a unique opportunity to hold paid apprenticeships while continuing their education, featuring both a STEM-focused secondary school program and a student-staffed Southwire satellite plant. 12 for Life’s classes and apprenticeships feature low teacher-student (1:10) and supervisor-student (1:12) ratios. The 12 for Life program aims to improve students’ academic performance, behavior, and retention.
Comparison group students received business as usual academic instruction and student support services provided by the high schools they attended. Students were likely exposed to instruction and support services as they had been in the past.
Teachers in the 12 for Life intervention received several elements of support, including access to professional development, professional learning communities, STEM conferences, on-site and online trainings, and access to an engineering maintenance program for classroom technology. Teachers also received curriculum and replication guides and access to a STEM curriculum development specialist.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
