NEW YORK – Hillary Rodham Clinton is unveiling a multi-year partnership here Tuesday with Univision, the influential Spanish-language media company, to promote the education, health and well-being of young children.

Too Small to Fail, the early childhood development initiative Clinton began last year, is teaming up with Univision to deliver expert research and commentary across Univision’s television programming. The message campaign, branded in Spanish as “Pequeños y Valiosos” (Young and Valuable), is designed to encourage Hispanic parents to actively engage their children five and younger to develop their language skills.

Clinton, a former secretary of state, will officially mark the new partnership with Univision and nonprofit officials at a Head Start program in East Harlem. The officials, including Univision Communications President and Chief Executive Randy Falco, will preview the first “Pequeños y Valiosos” public service announcement and participate in a roundtable discussion with some parents.

For Clinton, a potential 2016 presidential candidate, the partnership with Univision provides a valuable platform to promote her causes with the country’s fast-growing and politically influential Hispanic community.

Univision reaches nearly all of U.S. Hispanic television households and its audience is on a par with the country’s three major television networks, ABC, CBS and NBC. The company’s programming, which is spread across several networks, includes newscasts, drama series, sports, reality shows and sitcoms.

The partnership marks a major step forward for Too Small to Fail, a project Clinton began in the summer of 2013 through her family’s charitable foundation and Next Generation, a nonprofit group that promotes strategies for the development of young children.

The initiative focuses on closing what researchers call a “word gap,” as many children from lower-income families begin school with smaller vocabularies than their classmates. Since stepping down as secretary of state, Clinton has used her star power to attract public attention to this and other causes and to facilitate partnerships between corporations and nonprofit organizations.

In a video launching Too Small to Fail, Clinton said, “Our country’s future depends on healthy kids and loving families. They’re the building blocks of a strong and prosperous society.”

Early childhood development has been a passion of Clinton’s throughout her adult life. Upon graduation from Yale Law School, Clinton worked for the Children’s Defense Fund. And, as first lady, she published a book on the subject, “It Takes a Village: And Other Lessons Children Teach Us.”
