Los Angeles Unified has launched an online survey of some 170,000 parents in an effort to get as much input as possible about its proposed homework policy and other curriculum-related issues, officials said Monday.

The link to the survey will be sent to parents who have registered their email with LAUSD and also can be accessed on the computers located at the district's 500 parent centers. It is also available on the home page of the Office of Curriculum, Instruction and School Support at www.lausd.net. (The shortcut is http://bit.ly/AjMMj6.)

Results of the online poll will be anonymous and will be used by Los Angeles Unified officials and the school board to shape and decide district policies.

The survey includes questions about how much routine homework should count toward a student's academic grade, and how much homework should be assigned for various grade levels.
