Who benefits from SIOP instruction?

As the number of English learners increases in schools across the United States, educators are seeking effective ways to help them succeed in K-12 ESL, content area, and bilingual classrooms. Research shows that when teachers fully implement the SIOP Model, English learners' academic performance improves. Learn about the SIOP Model research base.

In addition, teachers report that SIOP-based teaching benefits all students, not just those who are learning English as an additional language.

SIOP instruction also benefits students learning content through another language. CAL has conducted research on adapting the SIOP Model for use in two-way immersion (dual language) programs.

Helping Educators Work Effectively with English Language Learners

The SIOP Model* is a research-based and validated model of sheltered instruction. Professional development in the SIOP Model helps teachers plan and deliver lessons that allow English learners to acquire academic knowledge as they develop English language proficiency.

The Sheltered Instruction Observation Protocol (SIOP) Model was developed to facilitate high quality instruction for ELs in content area teaching. It is used in hundreds of schools across the U.S. as well as in several other countries.

A system that provides a concrete structure to plan and implement sheltered instruction in the content areas.
