Michael Pound had a nicely done piece in the Beaver County Allegheny Times, which serves communities just west of Pittsburgh, that took a look at both full day kindergarten and the growing public investment in pre-kindergarten. Sounds like full-day and pre-k in the local school districts there meld together well. Elsewhere, of course, those two services are sometimes seen as being in competition for short funds. The recent study of the longterm effectiveness of the Chicago Child Parent Preschool program suggested that full day kindergarten, alone, had little effect if it wasn't paired with pre-k.
