I realise entry levels have to be set, but I feel past experience should be considered. Some teachers at my children's school have come straght from university, with little or no hands-on experience. Other teachers who have been in teaching for many years, have no degree and have limited exposure to computing.
Perhaps an entrance exam could be a way to select teachers with years of experience, but no degree. Other professions use this approach.
