About Language Tree Online

All students should have the opportunity to reach their full academic potential. Yet, many multilingual learners struggle with attaining the language proficiency needed to fully grasp subject matter content. This language barrier is what holds back even the most motivated students.

Curriculum development is led by David Noyes, a National Board-certified ELD educator with over 30 years of classroom experience. David deeply understands the challenges of teaching English to older students from highly diverse cultural and educational backgrounds. However, he could not find any tools that met the needs for newcomers and long-term English learners (LTELs) in the secondary grades.

This led David to partner with Language Tree to come out with the first standards-aligned ELD program that meets middle and high school English learners at their unique levels.



Our mission is to eliminate the language barrier to educational equity. We equip educators with the resources, tools, and training they need to deliver high-quality and meaningful English language development instruction to their multilingual learners.



David Noyes

Curriculum Lead

David leads curriculum development for Language Tree Online. He is a National Board-certified ELD educator with over 28 years of teaching experience and was named an Outstanding Educator of English Learners. As a result of his deep understanding of English language development standards, David was chosen to be an evaluator for the new English Language Proficiency Assessment of California (ELPAC).

David firmly believes that “language is the driver”, which means that building a solid foundation in language (rather than just focusing on vocabulary or content) is critical. This philosophy is infused throughout our course content.

David is also an award-winning curriculum writer, having developed K-5 curricula in the areas of Language Arts and English Language Development for Long Beach Unified School District and McGraw-Hill. David is a frequent presenter at industry conferences, including the California Association of Bilingual Education (CABE) conference.
