For our learners, a change of school and especially a change from primary to secondary is a very exciting, emotional, and important step. They get to know new teachers and classmates, a new school building and many new subjects. With regard to learning English, a further development in reading, writing, vocabulary and especially grammar takes place. In this contribution, we will look at four very specific and practical fields of action in order to successfully manage the transition from primary to secondary schools for learners of English as a foreign language. These include 1) the cooperation between primary and secondary schools, 2) diagnostic procedures, 3) content awareness, and 4) assessment.
