Maryland Career Clusters are a resource for high schools as they reorganize into smaller learning communities. Instruction is organized around career themes, providing more students the opportunity to explore career choices while still in high school and enroll in pathway programs that enable them to successfully transition from high school to postsecondary education. Similarly, community colleges are adapting career clusters as a means of organizing degree programs to ease the transition of students from high school and provide focused programs of study. Because learning is a lifelong process, Maryland educators have taken steps to ensure that high school students can readily transition to two-year colleges, four-year colleges, or other postsecondary education to reach their goals. Through articulated Tech Prep and CTE pathway programs, students take a sequence of courses beginning in high school and continuing at two- or four-year colleges without repeating material already mastered. This document provides an overview, along with a guide to Maryland's 10 Career Clusters.
