The Job Mix Formula (JMF) website has been developed in compliance with Section D of the California Government Code 11135. Code 11135 requires that all electronic and information technology developed or purchased by the State of California Government is accessible to people with disabilities. There are various types of physical disabilities that impact user interaction on the web. Vision loss, hearing loss, limited manual dexterity, and cognitive disabilities are examples, with each having different means by which to access electronic information effectively. Our goal is to provide a good web experience for all visitors.

We are constantly updating our content and striving to make it accessible. If you have any questions or suggestions, please contact the JMF Administrator.
