Dayna Straehley writes in The Press Enterprise:

A comprehensive approach to skills is needed because fragmented approaches don’t work [Heckman] said.
And national policy debates have ignored what he said are two essential ideas:

1. Parents matter a lot, not only in supporting their kids in school but also getting them ready for school, and

2. Success in life depends on a lot more than your scores on standardized tests.

Those soft skills – like character, self-control, perseverance, being able to plan tasks and set goals, and getting along with others – that lead to success should begin well before kindergarten.

Want numbers?

The rate of return on investment in early childhood education is 7 percent to 10 percent per annum, not counting improved health, which is another benefit that Heckman said he hopes to quantify in the next six months.
