Why are Wales's schools falling behind? Welsh schools do not appear to be achieving results as good as those in England - on several measures the gap is widening. The CBI, the employers organisation has called for urgent action; an inspection report says a fifth of Welsh students are functionally illiterate when they get to secondary school in Wales. David Reynolds, professor of educational effectiveness at the University of Southampton and a senior policy adviser to the Welsh education department and Philip Dixon, director of the Association of Teachers and Lecturers in Wales, examine what needs to be done.
