Thousands of four- and five-year-olds across Ontario are going to school full-time for the first time Tuesday.

But critics say the government still hasn't figured out the ABCs of running its ambitious all-day kindergarten program.

About 600 schools are offering full-day kindergarten this fall and Premier Dalton McGuinty has promised it will be available to every child by 2015.

But Annie Kidder, of the group People for Education, says the implementation of the program has left a lot to be desired.

Only 10 to 15 per cent of schools will offer after-hours child care that was a key component of the original plan.

Opposition parties say that's not the only problem.

Conservative critic Elizabeth Witmer says some school boards are siphoning money from other areas in the scramble to fund full-day kindergarten.

NDP critic Rosario Marchese says school boards are worried about the program because they aren't getting enough money from the government to pull it off.
