In several schools visited during the review, specialised teachers, sometimes called coaches or impact coaches, had less teaching responsibilities and more time devoted to working with individual teachers on their teaching practice. This practice was largely voluntary and teachers experiencing this type of work expressed very positive feelings regarding their experiences. Pedagogues are trained in supporting all stages of human development from birth to old age and can be specialised in early childhood education and care, leisure and youth education (Skolejritidsordning og Fritidshjem, SFO), or other areas of particular interest in the school system. Depending on the context in which they work, they might be compared to recreational instructors, play workers or social workers.
