You'll find that info on the school district website.

Kindergarten, it has to be offered half day at no charge. Some districts offer full day at no charge, others offer it with a charge, others don't full it at all.

Usually it's a couple grand if it's offered and there's often a lottery for the limited full day spaces.

This article from a couple of years ago would suggest it's a full day however I'd always confirm with the school directly.
