You’re here because you’re ready to support your English Language Learners (ELLs) and engage every student. TESOL Trainers is the right place to start. We’re committed to helping K-12 educators reach students using a model that makes content more accessible, comprehensible, and engaging for all students called the Sheltered Instruction Observation Protocol (SIOP) model.
With Dr. John Kongsvik at the helm, TESOL Trainers offers the #1 experiential SIOP professional development in the USA. Teachers experience real strategies in real-time through model lessons, interactive workshops, and hands-on techniques they can start using immediately. Schools across the country trust TESOL Trainers to provide research-based, practical solutions that set all students up for success.
Whether you’re looking for a one-day introduction or an in-depth, multi-day training, we’ve got an option that fits your school’s needs. Choose from one of our five SIOP programs below to start your school’s journey toward effective, empowered teaching.
This one-day course offers a foundational look at SIOP. Teachers role-play as students, experience a model lesson, and unpack it together to reveal the principles of sheltered instruction. By the end of the day, teachers walk away with a clear understanding of the SIOP framework, plus 10 practical strategies to connect ELLs with content and their peers.

This two-day training dives into the SIOP framework and its classroom applications. Day One covers four key SIOP components—Lesson Preparation, Lesson Delivery, Practice and Application, and Comprehensible Input—through active, model-based learning. On Day Two, we focus on language ownership and provide strategies to help students move from “renting” language to “owning” it, especially in content areas like math and science.
"This two-day course was eye-opening. I left feeling confident and ready to implement SIOP strategies. My students are more engaged, and I’m more effective." – High School Math Teacher

This four-day training, split into Parts 1 and 2, provides a comprehensive understanding of all eight SIOP components. Part 1 covers core elements to help teachers create accessible lessons, while Part 2 focuses on advanced practices, including integrating language domains, fostering metacognition, and building background knowledge. Teachers also learn strategies to reach reluctant learners and increase student engagement.
"Our entire staff did the four-day SIOP training, and the change in our classrooms was profound. The strategies we learned continue to benefit our students every day." – District Administrator

Combining either Part 1 or Part 2 SIOP training with peer coaching, this option helps teachers put their training into practice. Teachers observe each other, provide feedback, and receive ongoing support to apply SIOP strategies with confidence. Peer coaching boosts implementation rates up to 90%, as teachers collaborate to deepen their skills and reinforce best practices.
"The peer coaching made all the difference. Watching my colleagues teach, and receiving their feedback, helped me apply SIOP strategies so much more effectively." – Middle School ELL Specialist
