Officials of two education groups plan to train 50 teachers to instruct their colleagues on Louisiana’s new educator evaluations and changing curriculum.

The training will be done by the Associated Professional Educators of Louisiana, or A+PEL, and Stand for Children, a non-profit advocacy group.

The two organizations will identify, train and deploy teachers — they are called instructional all-stars — to serve as coaches while the changes are implemented.

Under new state rules, half of the annual evaluation for many teachers will be linked to the growth of student achievement.

The other half will be tied to traditional classroom observations by principals and others.

In addition, the state is ushering in a more rigorous curriculum for public schools that most states have adopted.
