Preschool teachers and reading study

Study: Preschool teachers benefit from mentorship, data
Knowing more about their students' pre-reading skills helps teachers even if they haven't received formal education training, according to a University of Texas study of 158 preschools in four states. Mentor programs and a handheld computer that provided feedback greatly improved students' learning, regardless of whether a preschool teacher was certified or formally trained.
