The SIOP Model

The research-based SIOP Model* of sheltered instruction has proven effective with English language learners (ELLs) throughout the United States. The SIOP Model is organized around the following eight components essential for making content comprehensible for ELLs:

  • Lesson preparation

  • Building background

  • Comprehensible input

  • Strategies

  • Interaction

  • Practice/Application

  • Lesson delivery

  • Review & Assessment

Teachers trained in the SIOP Model learn to plan and implement lessons organized around these components, which address the distinct academic and language needs of their students.

Visit the CAL SIOP website to learn more about the SIOP Model.

Professional Development on the SIOP Model

Teachers participating in SIOP Model professional development learn to plan and implement lessons organized around the eight components of the SIOP Model. These lessons help students develop their academic English skills while they are learning grade level content. Professional development includes a variety of activities, such as demonstration, analysis of video teaching sequences, small group tasks, and creation of instructional activities. Learn more about professional development using the SIOP Model.

To discuss SIOP Model professional development activities for your school or school system, please contact the SIOP team via email or 202-362-0700.

*The SIOP Model was developed by researchers at California State University, Long Beach (Jana Echevarria and Mary Ellen Vogt), and the Center for Applied Linguistics (Deborah J. Short) under the auspices of the Center for Research on Education, Diversity & Excellence (CREDE), a national research center funded by the U.S. Department of Education from 1996 through 2003.
