Here's just one example: After almost a year in Head Start (with an average cost of about $ 7,700 in 2005), children were able to name only about two more letters
than their non — Head Start
counterparts, and they did not show any significant gains on much more important measures, such as early math learning, vocabulary, oral comprehension (more indicative of later reading comprehension),
motivation to learn, or social competencies, including the ability to interact with peers and teachers.
