The Federated States of Micronesia National Department of Education (FSM NDOE) requested support from the Region 18 Comprehensive Center (R18CC) to build National and State-level knowledge of effective practices in bilingual and multilingual education. This scan offers an overview of evidence-based practices for implementing and evaluating the effectiveness of bilingual and multilingual education programs. The scan assumes that bilingual/multilingual education programs are based on the goals of two-way and immersion programs that may also accommodate heritage learning. It first begins with a brief overview of definitions of major terms utilized through the document, and then moves to discuss the following components of program implementation: (1) Program Planning and Implementation; (2) Educator Quality and Pedagogic Practice; (3) Engaging Families and Communities; (4) Assessment, Accountability, and Evaluation.
