English Language Development Curriculum

Overcome the Roadblocks Impeding English Learner Progress

Why has progress stalled for some English learners, even after many years of study? The key to unlocking English language proficiency requires understanding how language works and functions in our daily lives. Unfortunately, most literacy resources only offer minimal support in building language skills.

Language Tree Online is different. Our English language development (ELD) programs are fully aligned with the latest English language proficiency standards to keep the focus on language acquisition and development. They feature:

Sheltered Instructional Strategies

Video, image, and audio support help make new concepts easier to grasp and keep learners engaged.

Culturally Relevant Pedagogy

Stories reflect meaningful aspects of English learners' identities and daily lives.

Age-Appropriate and Leveled Content

Targeted levels specifically for middle and high school English learners

Use our hybrid ELD/ESOL curriculum as a supplemental resource or as the instructional foundation for designated ELD time, English Language Arts, or extended learning opportunities. Language Tree Online can typically be purchased using Title III, Title I, or ESSER funding.



For recently arrived students with any degree of language proficiency, our Newcomers module provides acculturation support to build confidence in a new school environment. For English language learners with limited transferable language skills, we offer functional vocabulary builders and highly scaffolded language lessons aligned with the standards.

ELD Level 1

Beginning and Emerging

ELD Level 1 is an English language development program for beginner ELLs in the secondary grades. Our ELD curriculum addresses all four domains of language. Standards-based assessments, online lessons with oral practice, teacher-led instructional routines, and built-in intervention resources work together to accelerate English language acquisition.

The Language Tree Online program has been such an amazing resource for both myself and my students. There were multiple options when it came to learning. Students were able to work independently at their own pace. I was also able to easily check on student progress through the program.

This is a great program. I adapt the extension activities to make assignments and projects for my students. There is a lot of granular skills that I would overlook if not for Language Tree Online.


The best thing I like about the program is that they're explaining things really well, easy to understand.

Flexible Instruction

As the teacher, you are the pilot and our program is the co-pilot! Use our program as often as you like to support your instruction. Our program can be used for both in-class and remote learning. Students can learn and practice anywhere using any connected device.


Language Assessments

Standards-based formative assessments identify specific language gaps, so you know where to focus instructional time. Summative assessments taken after program completion show learning growth and help indicate which skills still need to be developed.

The Vocabulary Builder section of American School Culture was very helpful.  It provided new terms applicable to the video subject content of the chapter and helped my students listen more actively when reviewing the video content a second time.”  Stacy Lica, EL Coach Jordan high school.
