THE old adage "bad things come in threes" might soon apply to the community preschool system, with the state government set to cut funding to three-year-olds.
Kiama Preschool took part in the "red day of action" on Thursday in support of a rally outside Parliament House, wearing red and adding their hand prints to the banner, "3 year olds matter".
Director Maria Whitcher said the government wanted to target funding at children in the year leading up to school.
"Their rationale is that the children who are three will have two years, so they're not going to qualify for funding, "she said.
"Now they want to increase funding to four-year-olds but they're doing that by taking funding away from three-year-olds."
She said the cost to send a three-year-old to preschool could blow out to $70 a day; fees are currently $32 a day.
"If funding's taken away from three-year-olds, it is neither going to be affordable or accessible to families," she said.
"They have also suggested that some preschools will receive less funding. If this occurs to Kiama Preschool, our fees will have to increase for all ages."
The OECD reported children across the world who access early education have improved cognitive abilities and higher reading abilities at age 15.
Ms Whitcher said the benefits extended even further.
"There's been a long-term study in America that showed people who went to quality early childhood preschools and long daycare had much better outcomes as adults. There was much less early intervention in schools and even longer term, much less incidents of crime," she said.
Parents at the preschool have signed letters to be sent to Education Minister Adrian Piccoli.
