Are you thinking of starting a dual immersion (DI) program in your district or at your site? Research shows it to be one of the most effective programs for all students, including English Learners, as it develops high levels of academic achievement and biliteracy.

Starting a DI program involves many stakeholders and requires collaboration and support in making the decisions, both policy and pedagogical, necessary to create and launch a strong, successful, and sustainable DI program.

We recommend that any district or site wanting to start a new DI program use the Guiding Principles for Dual Language Education, the publication from the Center for Applied Linguistics (CAL) in Washington, D.C, which is based on the research on dual language education. The seven strands in the Guiding Principles provide guidance in building a DI program that will deliver on the promise of the research findings.

We also recommend taking at least one full year for planning to allow adequate time to examine the many options there are for the various aspects and components of DI and to determine the most appropriate ones for your district and site.

In this DI Planning Guide, we draw upon the Guiding Principles for Dual Language Education in providing and explaining the steps in a series of modules for you to consider in order to plan and structure for the launch of a strong, successful, and sustainable DI program.
