“That’s where professors Stephanie Jones and Nonie Lesaux at the Harvard Graduate School of Education come in.

“They’re launching a study, ‘The Saul Zaentz Early Education Initiative’.

“They’re gathering information from 5,000 families in Massachusetts with three and four-year-old children and plan to follow them over the next five years – all of the information will be confidential.

“‘It’s a ground-breaking study that will influence conversations and policies around early education in the U.S. with the goal of doing better with all children and their families,’ said Lesaux.

“Nationwide, preschool is expensive and the quality can be uneven.

“‘The challenge, actually, is only two in 10 experiences are high quality so only two in 10 children have access to a high quality early education experience,’ said Jones.”
