The Schools Council Project on Statistical Education, working in England and Wales and based at the University of Sheffield, was the first national project in the world to look specifically at the statistical education needs of all pupils in the 11-16 age range and to develop teaching materials to meet these needs. In this paper I have tried to show some of the many things anyone developing new teaching materials has to take into account. I have indicated how they affected the teaching material of the Schools Council Project on Statistical Education and the approach taken by the project team. I hope that this will help any of you who have to develop teaching material in your own countries to identify the areas of concern and produce relevant material for you pupils.
