Parents and educators renewed efforts Friday to bring full-day pre-kindergarten to all of Long Island's school districts.

"If they had a full day, it's consistent," says Leah Tozer, whose daughter went through a half-day program at Lido Beach Elementary School. "They're in one place. They're comfortable. They're learning. They're socializing. It's a nice base for them before getting into kindergarten."

A News 12-Newsday investigation found that across the island, only 25 districts offer full-day pre-K. At least 50 others have half-day programs. Eleven districts offer a combination of the two.

One of the biggest obstacles to full-day pre-K is funding, according to officials.

In Long Beach, the state covers around a third of the cost of the district's pre-K program. Taxpayers shoulder the rest of the burden.

Tax activist Pat Friedman says taxpayers are already struggling to pay high school taxes in the area.

Officials say full-day pre-K would be more affordable if Long Island districts got a fair share of state aid.

"We have high-needs families, but we're considered an average wealth district and therefore don't qualify under the full-day funding formula that has been established by the state," says David Weiss, the superintendent of Long Beach schools.
