Denish needs to elaborate on Pre-K claim

During the debate yesterday, Lt Gov Diane Denish said she planned to continue her push for Pre-K programs; programs which some call "government daycare".

Denish claimed 24% improvements in children who went to Pre-K.

A quick internet search on the effectiveness of Pre-K points to some disagreement on the overall efficacy. In a nutshell, the data seems to indicate short term gains that disappear by the second or third grade, link.

Since the programs are expensive, it behooves us to dig a little deeper; beginning with expecting Denish to offer some elaboration and corroboration of her claim.
