The series has been developed around age-appropriate, cross-curricular topics that develop students' critical thinking and examination techniques. It follows cm integrated skills approach with each of the skills brought together at the end of each unit. The Boost! Speaking component is dedicated to some key people who have been instrumental in helping me grow as an EFL professional namely Cordon Lewis, Jake Kimball and Andrew Wright. I'd also like to thank the many colleagues who enjoyed discussing YL. and leenager educational issues with through Korea TESOL and the IATEFL Young I-earners and Teenagers Special Interest Group.
