@Animandel - Sure we want decent people as preschool teachers, but you are taking the concept too far if you expect preschool teachers to meet the same requirements as teachers who teach school-aged kids.
I know a young girl who works with preschoolers at the local church preschool program. She is great with the children and they love her. If she had to have a college degree then she would not be doing the job. I see preschool teachers more as teacher's aides rather than teachers in the traditional sense.
