Welcome to The TEFL Lab! 

We're passionate about designing curricula, tools, and resources that help English teachers maximize their impact in the classroom and minimize their prep.  

 Meet the Founders!


Jacqueline Sedore 

As a former TEFL certification instructor and academic coordinator, Jacqueline’s experience in teacher training and EFL teaching is a key piece of the work The TEFL Lab is doing to empower teachers in the EFL classroom and beyond. Having lived in Spanish-speaking Chile, Jacqueline not only worked as an EFL teacher and mentor, but became a second language student herself and she applies this knowledge and experience to the lessons and training programs we design and provide for teachers around the world.



Rachel Laycook 

With over 12 years of experience in the classroom, Rachel’s work as an EFL teacher and learner experience manager combine with her background in education and linguistics research to form an essential part of The TEFL Lab’s mission: to support and improve the quality of EFL instruction around the world.  As a bilingual adult learner and teacher of adults, she understands the unique challenges and opportunities to be addressed through content and instruction in the EFL classroom.


We share our expertise through The TEFL Lab lessons and teacher tools but we also strive to inspire and guide your teaching through our blog posts.
