Could all-day kindergarten become a casualty of the state budget crisis?

Posted: Updated:

PHOENIX -- An Arizona state senator says it's time to take at hard look at all-day kindergarten, a program that's just three years old.

Sen. John Huppenthal made the comment during a forum on education funding. Pointing to second-graders' test scores, he says all-day kindergarten has not given students a significant boost since its implementation in 2006.

State Superintendent Tom Horne disagrees.
