REL Pacific at McREL, one of 10 Regional Educational Laboratories (RELs) funded by the U.S. Department of Education's Institute of Education Sciences (IES), serves educators in American Samoa, the Commonwealth of the Northern Mariana Islands, the Federated States of Micronesia (Chuuk, Kosrae, Pohnpei, and Yap), Guam, Hawai'i, the Republic of the Marshall Islands, and the Republic of Palau. REL Pacific is committed to providing educators with resources that support the development of a deep and cohesive body of knowledge in priority topic areas. Like REL Pacific, other RELs across the United States and in Puerto Rico and the Virgin Islands have developed studies that address these topics. In this Research Digest, the reader will find information on the purpose and design of several REL studies that focus on engaging families and communities in education, ensuring college and career readiness, optimizing data systems, and strengthening teacher effectiveness.
