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.
