CARSON CITY, Nev. (AP) — Implementing full-day kindergarten is a priority for Democrats in the Nevada Legislature, but the ambitious proposal comes with an as yet undetermined price tag or funding.

On Monday, the Senate and Assembly education committees hold a joint hearing on SB182, a measure that would require full-day kindergarten statewide. The bill would also lower to 5 from 7 the age at which a child must attend school.

Some early estimates put the cost at around $60 million.

Republican Gov. Brian Sandoval’s $6.5 billion general fund budget proposal includes $20 million to expand full-day kindergarten to more at-risk schools. But Democrats argue the effort doesn’t go far enough.

Besides the cost, some critics argue school districts lack classrooms and other resources to accommodate an influx of kindergarteners.
