A world-famous study by researchers Betty Hart and Todd Risley (1995) found that some children heard thirty million fewer words by their 3rd birthdays than others. The children who heard more words were better prepared when they entered school. These same kids, when followed into third grade, had bigger vocabularies, were stronger readers, and got higher test scores. The bottom line: the kids who started out ahead, stayed ahead; the kids who started out behind, stayed behind. This disparity in learning is referred to as the achievement gap.
We believe those thirty million words are key to closing the achievement gap and giving children the best start in life. That’s why we created the Thirty Million Words™ Initiative. We want to get the words out!
