Meet our DELTA team
Akcent International House is a Platinum Cambridge exam centre that has offered the DELTA courses for nearly 30 years. Our courses have launched hundreds of ELT teaching careers.
Jaime Lilley, CELTA/DELTA Tutor, Head of Teacher Training has been teaching since 2005 years, and training since 2009. 
She is a CELTA and DELTA tutor, and has been the head of Akcent's Teacher Training Centre since 2021. She maintains a lively teaching practice of adults, exam preparation, ESP students, and very young learners (4-6 years). She favours a responsive, learner-driven, humanistic, and democratic approach in the classroom.
In her non-teaching time, she publishes a poetry journal and enjoys the arts.
Adam Řehák, Teacher Training Centre Administrator, is your go-to person for questions
concerning CELTA and DELTA courses. He will guide you through the registration process and handle your accommodation, if requested. He works as the administrative support of Teacher Training Centre and provides communication with candidates or anyone else in need of assistance. As an anthropology graduate he is happy to meet people of various backgrounds and will be glad to help you as a guide for Czechia as a whole.
Betty Polišenská CELTA/DELTA Tutor has been training teachers on CELTA courses since 2001 and became a DELTA tutor in 2009. Over the years, she has trained teachers in many contexts across 
Europe, Africa and Asia. These days she trains teachers mainly online: she thinks it is a great way to make learning accessible, practical and autonomous. Her professional interests are task-based, purposeful and learner-driven learning, use of L1 and translation and implicit learning. Outside work, she enjoys being outdoors with her rough collie.
