Therefore, there is limited evidence so far on what professional development programmes really work for more effective teaching in diverse classrooms. The National Agency offers various programmes within eight different themes, one of which is newly arrived and multilingual children and students' learning. For instance, some of the courses within this theme are on the study and vocational guidance for newly arrived students as well as language and knowledge development within subject instruction for new arrivals. Another example of continuous professional development offered for teachers is A Boost for Teachers (Lararlyftet).
