This chapter is aimed at professionals in Scotland working with children attending Gaelic Medium Education (GME) presenting with speech, language and communication difficulties (SLCD). This typically includes speech and language therapists (SLTs), teachers, education staff and other related professionals. Space restrictions have in places limited the detail which could be included: we have therefore added a large number of references to enable the reader to explore the evidence in greater depth if they so wish. Given the statistical fact that the majority of SLTs working in Scotland will come from a monolingual English background this chapter is written from that perspective. Similarly, reflecting statistical facts, SLTs are referred to as “she” and children seeing SLTs as “he”.
