The wide-eyed kids who troop off for their first day of kindergarten in a few weeks could be the last group of B.C. five-year-olds to attend school for only half a day.

The provincial government is considering offering full-day kindergarten in time for the 2009 school year, with the program expanding on an optional basis to four- and three-year-olds by 2012.

The government first floated the idea last February in its throne speech and Friday is the deadline for public input into the idea.

A final report to the government is due by the end of the year, but Education Minister Shirley Bond could barely contain her enthusiasm for the idea on Thursday.

Bond said the idea fits with the government's education goals and is the logical next step in supporting families.

A cost estimate for the plan hasn't been done, but a former B.C. deputy education minister said when he looked into it almost 10 years ago, he found it would cost at least $95 million.

Charles Ungerleider, who is now an education researcher, said the investment would pay off in the long run with higher graduation rates and lower crime rates.

The Ontario government has promised to offer all-day kindergarten for four- and five-year-olds by 2010, and it is already in place in some school districts.
