“Since 2004, Tennessee has offered state-subsidized prekindergarten, enrolling more than 18,000 of the state’s neediest 4-year-olds. An early evaluation showed that, as you’d expect, youngsters who attended pre-K made substantial gains in math, language and reading. But, startlingly, the gains had evaporated by the end of kindergarten…”
“Have the claims made for early education been overblown? Not necessarily. Consider what’s happening in Boston. A randomized study showed that prekindergartners there gained between four and seven months’ progress in reading and math, and those gains persisted: 27 percent more of Boston’s preschool children scored ‘proficient’ or better on the state’s rigorous third-grade exams.
“What’s the difference between Boston and Tennessee? In a word, quality.”
