Early identification of significant hearing loss is essential to enable timely intervention to safeguard against the effect of hearing loss. Hearing loss can be temporary or permanent but, depending upon the severity, both can have a significant impact on a child’s speech and language development, educational achievement and general development, with a longer-term risk to mental health and quality of life. Hearing screening programmes are undertaken to identify hearing loss and thereby enable active intervention to provide children with access to sound. Timing of the screen has been tried at two points: newborn and school entry. Several countries now have both newborn hearing screening programmes (WHO 2010), and school entry screening programmes (Skar y ski 2012). This makes it possible to identify and address hearing loss in a timely manner and thereby minimise its negative impact on speech and language development, education and general development. In the UK, school entry hearing screening has been in place since the 1950s, with universal newborn hearing screening being introduced between 2002 and 2006. A recent presentation reports that Tests for screening for hearing loss in children about to start school (Protocol).
