Helping Educators Work Effectively with English Language Learners
As the number of English learners increases in schools across the United States, educators are seeking effective ways to help them acquire the knowledge and skills they need to succeed in the classroom and beyond.
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.
Learn more about the SIOP Model.
CAL participated in the development of the SIOP Model and continues to conduct SIOP research. Our experienced SIOP team of educators and
researchers provides professional development services on the SIOP Model through workshops, site visits, coaching sessions, and technical assistance. CAL's SIOP team designs and provides high-quality services that address the particular needs of districts and schools.
