CAL SIOP and Sheltered Instruction

The Sheltered Instruction Observation Protocol (SIOP) Model is an instructional model for lesson design and delivery. It is based on and validated by research, and it has proven effective in addressing the academic needs of English learners in the United States and around the world.

The SIOP Model comprises eight interrelated components: lesson preparation, building background, comprehensible input, strategies, interaction, practice/application, lesson delivery, and review/assessment. Using instructional strategies connected to each component, teachers design and deliver lessons addressing English learners’ academic and linguistic needs.

As the number of English learners increases in schools across the United States, educators seek effective ways to help them succeed in the classroom. Research shows that when teachers implement the SIOP Model, the academic performance of English learners improves. Teachers report that SIOP-based teaching benefits all students, not only those learning English as an additional language.
