NEW TWBI/DLI EDUCATOR INSTITUTE

UPDATE - SHIFT TO VIRTUAL

The two-day virtual institute will take place on July 27–28, with live online sessions from 9:00 AM – 12:00 PM (Pacific Time) each day. Participating virtually allows educators and leadership teams from anywhere to join without the need for travel while still engaging in interactive learning and discussion.

Day One focuses on the research, history, and foundational components of Two-Way Bilingual Immersion/Dual Language Immersion (TWBI/DLI) programs. Participants will explore the rationale for bilingual education, effective program models, and the critical elements that contribute to long-term success.

Day Two builds on those foundations by providing teachers and administrators with practical strategies, resources, and expert guidance to support a successful start to the school year. Sessions will focus on instructional best practices, bilingualism and biliteracy, assessment, and planning for implementation.

Throughout the institute, you’ll learn from experienced TWBI/DLI educators who will share proven practices, real-world experiences, and valuable resources to help your team launch or strengthen your program. Whether you’re just beginning your TWBI/DLI journey or looking to refine your existing program, these sessions are designed to provide both the foundational knowledge and practical tools needed for success.

We know that implementing a TWBI/DLI program is a collaborative effort, and the early years are often the most rewarding – and the most challenging. We look forward to learning with you this summer and hope you and your team will join us for this engaging and impactful professional development opportunity.

All attendees must cancel their registration, regardless of whether payment has been submitted or not – if you fail to cancel your registration, you will be required to pay for your conference registration.
