After lying dormant for a year, a bill to overhaul the state’s teacher evaluation law will resurface Monday, subject to continuing negotiations over its cost and some disagreements over its content.

AB 5’s prospects have improved with the support of the California Teachers Association. CTA expressed reservations a year ago, but the bill’s author, Assemblymember Felipe Fuentes, a Democrat from the San Fernando Valley, agreed last summer to a few key changes, so now the union favors it, CTA lobbyist Patricia Rucker said this week. One amendment would require training administrators to do uniform and knowledgeable evaluations.

The bill, which would require that all districts evaluate every teacher based on a set of attributes and practices outlined in the bill, is similar to an evaluation framework that the union adopted earlier this year, Rucker said. AB 5, she said, “is a clear and good policy document.”
