A new law that spells out the rights of transgender students in kindergarten through 12th grade is set to take effect in California on Jan. 1. To get ready, school districts are reviewing locker room layouts, scheduling sensitivity training for staff and reconsidering senior portrait dress codes.

But educators also are watching and waiting. The first-of-its-kind statute could end up suspended within days of its launch if a referendum to repeal it qualifies for the November ballot.

To obtain a public vote on the law, a coalition of conservative groups has collected hundreds of thousands of signatures. Counties have until Jan. 8 to verify them through spot-checking.

The secretary of state can approve the referendum, determine that it failed or order a review of every signature.
