TESOL Trainers Inc

SIOP® Training That Changes How Teachers Teach

Experiential K-12 professional development built on the SIOP® model. Your teachers experience every strategy as learners before they use it with students. Not a lecture. Not a webinar. The kind of training that makes teachers say, 'This is the best PD I've ever had.'

I'm Dr. John Kongsvik, and for 25 years I've been training K-12 teachers to reach English Learners and every student in their classrooms. I do it using the SIOP® model the most widely researched framework for sheltered instruction in education - and I teach it the way I want your teachers to teach: experientially, interactively, and with zero percent sit-and-get.
Schools across the country choose TESOL Trainers because our training is different. Teachers don't sit and listen. They participate in real model lessons, experience strategies firsthand, and leave with practical techniques they can use Monday morning. That's not a tagline. That's what happens in every session I deliver.

Whether you need a one-day SIOP® introduction, a four-day deep dive through the English Learner Institute or a multi-year partnership with iCOACH peer coaching , we'll design a program that fits your school and transforms your teaching.

What is SIOP?
SIOP stands for Sheltered Instruction Observation Protocol. It is a research-based instructional framework with 8 components and 30 features designed to make academic content accessible for English Learners while benefiting all students. Developed by Jana Echevarría, MaryEllen Vogt, and Deborah Short, SIOP gives teachers a clear system for planning, teaching, and reflecting on lessons that integrate content and language development. It is the most widely used sheltered instruction model in K-12 education in the United States.
What is sheltered instruction?
Sheltered instruction is an approach to teaching that makes academic content accessible to English Learners while they are developing English proficiency. Rather than simplifying the content, sheltered instruction uses strategies like visual supports, vocabulary instruction, cooperative learning, and scaffolding to help students access grade-level material. The SIOP model is the most recognized framework for implementing sheltered instruction in K-12 classrooms.
Is SIOP only for English Learners?
No. While SIOP was originally designed to support English Learners, the strategies it provides benefit every student in the classroom. Clear objectives, scaffolded instruction, vocabulary support, meaningful interaction, and ongoing assessment are effective teaching practices for all learners. Many schools implement SIOP schoolwide because it raises the quality of instruction across the board.
What are the 8 components of SIOP?
The eight SIOP components are: Lesson Preparation, Building Background, Comprehensible Input, Strategies, Interaction, Practice and Application, Lesson Delivery, and Review and Assessment. Each component contains specific features that guide teachers in designing and delivering effective instruction for English Learners and all students. Together, the 8 components cover every aspect of a lesson from planning through assessment.
What professional development does TESOL Trainers offer?
TESOL Trainers provides experiential, interactive professional development for K-12 educators on SIOP, TESOL strategies, scaffolding, student engagement, academic vocabulary, active listening, peer coaching, and more. Our flagship program is the English Learner Institute (ELI), a fully remote, live training built on the SIOP framework. We also offer customized onsite and virtual training for individual schools and districts. All of our PD is hands-on and interactive — never sit-and-get.
How is TESOL Trainers' professional development different from other PD providers?
Three things set us apart. First, our training is 100% experiential: Dr. Kongsvik teaches the training the way he wants teachers to teach, so participants experience every strategy firsthand as learners. Second, participants are engaged 100% of the time — there are no lectures, no passive listening, and no sitting while one person presents. Third, every strategy we teach is practical and classroom-ready. Teachers can implement what they learn the very next day.
Does TESOL Trainers provide training both onsite and online?
Yes. We provide K-12 professional development both onsite at your school or district and remotely via Zoom. We also offer hybrid formats where part of the training is delivered onsite and part virtually. Our remote training has been rated 5 stars by over 1,500 educators, and participants consistently say it feels as engaging as in-person PD.
Can TESOL Trainers customize training for our school or district?
Absolutely. We tailor-make our professional development to meet the specific needs of your institution. Whether you need a one-day SIOP overview, a multi-day institute, targeted training on a specific component like engagement or scaffolding, or a long-term partnership with peer coaching, we can design a program that fits. Many of our longest-running clients have been with us for five or more years.
Does TESOL Trainers offer peer coaching?
Yes. We offer iCOACH, our structured peer coaching program that dramatically increases the transfer of training into classroom practice. Research shows that training alone leads to about 10% implementation. When peer coaching is added, implementation rates jump to 90% or higher. iCOACH pairs teachers to observe each other, provide descriptive feedback, and support each other in applying new strategies. It is available as an add-on to any of our SIOP training programs.
Do participants receive certificates?
Yes. All participants who successfully complete our training sessions receive a certificate that states the type of training attended and the total contact hours. These certificates can be used toward professional development requirements in most states and districts.
Does TESOL Trainers work with schools internationally?
Yes. In addition to working with K-12 schools across the United States, Dr. John Kongsvik and his team have provided professional development to educational institutions in Asia, Africa, South America, and beyond. We offer both virtual and onsite international training.

Remote K-12 PD Same experiential training, delivered live on Zoom. Feels face-to-face.

There are hundreds of PD providers in education. Here's what makes TESOL Trainers different:
I teach SIOP® using SIOP®. Participants don't hear about model lessons. They're IN a model lesson from the moment we start. Every strategy I teach, I model live. That's not theory - it's practice.

Teachers are engaged 100% of the time. In my training, there's no sitting and listening while someone clicks through slides. Teachers are active participants from start to finish - pair sharing, cooperative learning, sentence starters, hands-on activities.
Every strategy is classroom-ready. No adaptation needed. No extra prep time. The techniques teachers learn in my training can be used the very next day, in any subject, at any grade level.

iCOACH makes it stick. Most PD has a 10% implementation rate. Add our iCOACH peer coaching program and that number jumps to 90%.
