Dual Language Immersion Specialists

Language is the heart of dual language immersion. That is what makes these programs so special: a student’s language proficiency is the foundation for all other core subjects.

Learners thrive in an environment where they are challenged linguistically in everyday contexts and develop holistic knowledge of real-world language use. Parents enroll their students for the purpose of achieving proficiency in two or more languages.

So why is language proficiency often overlooked? With MEDLI, it’s not.

MORE Effective Dual Language Immersion (MEDLI) is a global initiative with a mission to fulfill the promise of DLI– to create a world where every child is multilingual.

What makes for a high-quality and long-lasting DLI program? Accountability. How do you get accountability? Proficiency-based assessment.

Begin with Proficiency in Mind

The key to building a highly effective dual language immersion program is accountability through language proficiency assessment data and strong instructional practices that build proficiency.

Proficiency through a DLI lens describes the language learners’ needs, both developmentally and cognitively, as they grow through the DLI program.

Language proficiency assessment tools like Avant STAMP provide the accurate and reliable benchmarking needed to:

  • inform curriculum practices.
  • demonstrate learner growth.
  • showcase program efficacy.
  • enable proactive planning for hiring and MORE!

Avant STAMPe is effective in benchmarking as early as K-1.

And, we never delete the data, so you can conduct longitudinal analyses — perfect for DLI programs.
