Maybe we need some better way of checking ages. I know that analyses of teeth are not sufficiently reliable but I'd have thought that some sort of system could be developed which includes physical measurrs such as teeth, facial hair, stage of puberty; and this could be coupled with assessments/estimates made by teachers/youth workers and be by other children. As a teacher I can usually make a pretty good estimate of ages which are normally right to within a year- the only exception being bearded students, usually of Pakistani or North African heritage, who sometime seem to be significanly older than their Home Office age and I do sometimes find myself checking whether at 14 they drive a car or are have children. Maybe a panel could be set up and an average be calculated. From my involvement in junior football i was also aware of some under 13s with dubious documentation who could easily have passed for 17
