Mayor Antonio Villaraigosa is scheduled to be in Sacramento today to share his position on teacher evaluations with a group of educational policymakers.

Villaraigosa will give the keynote address at the Education Trust-West summit titled, "Innovations in Teacher Evaluation: A Forum to Showcase Promising Practices and Discuss Implications for State Policy."

Villaraigosa will call for basing teacher evaluations on multiple measures, including in-class observation, feedback from fellow teachers, parents and students and "student growth over time," an aide said.

Villaraigosa is scheduled to return to Southern California in time to deliver welcoming remarks at NBC News Education Nation Job One Panel at the Pacific Design Center in West Hollywood tonight.

Although the mayor of Los Angeles has no formal role in education, Villaraigosa has made education one of his priorities since taking office in 2005.

Villaraigosa operates the Partnership for Los Angeles Schools, an independent educational nonprofit group that operates 21 schools in partnership with the Los Angeles Unified School District.

The trip will be Villaraigosa's fifth in 22 days.

He was in Chicago April 28-29 for the National Summit on City Design; in Washington, D.C. May 3-4 for meetings on education and transportation; in Sacramento May 11 to meet with legislative leaders of both parties to discuss education funding; and in Chicago Saturday through Monday

for Rahm Emanuel's inauguration as mayor.
