The League's College and Careers Transition Initiative (CCTI) engaged high schools, community colleges, and businesses in a process to improve career and technical education systems, programs, strategies, and outcomes. This monograph reports on examples of these systems changes that resulted from CCTI participation: expanded use of career pathways; improved academic instruction; improved CTE instruction; measures to improve college readiness; high school-college partnerships and articulation; education-business partnerships; advising and student success initiatives; and data-driven decision making. Each of these systems changes influenced the educational opportunities available to a wide range of students.
