The Sheltered Instruction Observation Protocol (SIOP) Model is a research-based and validated instructional model for lesson design and delivery that has proven effective in addressing the academic needs of English learners throughout the United States and around the world.

The SIOP Model consists of eight interrelated components: lesson preparation, building background, comprehensible input, strategies, interaction, practice/application, lesson delivery, and review/assessment. Using instructional strategies connected to each of these components, teachers are able to design and deliver lessons that address the academic and linguistic needs of English learners.

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

Professional Development Services

CAL’s experienced SIOP team works closely with schools, districts, and states to plan, implement, and support instruction using the SIOP Model. Informed by CAL’s ongoing research, CAL offers a suite of professional development offerings that can be tailored to fit your needs and context.

CAL SIOP offers professional development services specifically tailored to grade level and content areas to help educators understand how the SIOP Model’s components can be successfully implemented for their students. Our PD services can help early childhood educators incorporate instructional routines that promote more peer to peer interaction; Career and Technical Education teachers identify academic language specific to content areas such as visual arts, computer programming, and mechanics; and science teachers create instructional activities that provide English learners with opportunities to apply both science content and language knowledge.
