The risk appears to be very low, even if it is not possible to supervise the children continuously. One, now quite old study[1] found that in the 20 years from 1958 - 1977 484 children died of poisoning in the UK. Only three involved plants, and non yew. The authors argue that "Plants are the most overrated poisons of childhood". Interestingly, they also suggest that laburnum is often cited as the most poisonous plant, yet though I've several times come across worries about yew in schools, I've never heard concerns being expressed about laburnum. There are many, many poisonous plants and most go unnoticed. I suspect that the fame of yew as poisonous is ill deserved, and concerns often centre around the belief that the red berries look attractive to children. Most of the literature on yew poisoning is about horses or cattle eating foliage, and even those few case studies of human poisoning I can find tend to be caused by foliage. The flesh of the berries isn't actually poisonous, although the seed inside is.
