Protects public by ensuring those classified as social workers meet national educational standards
SACRAMENTO – Assembly Bill 252, jointly authored by Assemblymember Mariko Yamada (D-Davis) and Assemblymember Susan Eggman (D-Stockton) - both professional social workers - passed the Assembly Business, Professions, and Consumer Protection Committee Tuesday with strong bipartisan support.

“Today, there are still public and private agencies that classify employees as social workers who have not completed the coursework, supervised field instruction and ethical training required by a social work education,” Assemblymember Yamada stated. “With the growing complexity of service needs in our state, AB 252 seeks to protect consumers of social work services and the integrity of the profession, which is now 115 years old.”

Assemblymember Yamada Introduces the Home Care Services Act of 2013

“California is aging, and is already home to the largest population of dependent adults in the nation,” Yamada said. “There should be clear standards for training and background checks for agency-based caregivers who wish to serve this vulnerable population.”
Assemblymembers Yamada and Eggman Introduce Social Work Title Protection Bill
Protects public by ensuring those classified as social workers meet educational standards
SACRAMENTO – Assemblymember Mariko Yamada (D-Davis) and Assemblymember Susan Eggman (D-Stockton) introduced AB 252 today to ensure that individuals who are classified as social workers have earned a degree in social work at an accredited college or university.
“Social work is both a calling and a profession,” Yamada said. “The title ‘social worker’ presumes a high standard of education, a solid grounding in professional ethics, and rigorous real-world training. A consumer has the right to assume that a person with the title meets a high standard of competency and integrity, which cannot be guaranteed when services are provided without a social work degree.”
Employers use the title “social worker” inconsistently to describe many types of workers with varying experience and training. This misrepresentation can be harmful to vulnerable citizens who believe they are receiving care and services delivered by a qualified social worker who can use his or her professional judgment in life-threatening situations, including protecting the elderly from abuse and neglect and intervening in situations posing a serious danger to children.
“The title ‘social worker’ invokes the shared history, training, ethics and practices of a 115-year-old profession,” said Assemblymember Eggman. “We need to ensure that anyone who uses the title meets those well-established standards. This is about truth in advertising.”
AB 252 will require employers to assign the title of “social worker” only to individuals who hold a degree in social work from a school accredited by the Commission on Accreditation of the Council on Social Work Education (CSWE). Individuals will be prohibited from identifying as a social worker without the appropriate educational qualifications.
CSWE accreditation ensures that all who graduate with a social work degree have had coursework grounded in professional ethics, best practices and cultural diversity supplemented by at least 400 hours of supervised field instruction. Additionally, social worker conduct is bound by a Code of Ethics.
Legislation protecting the professional title “social worker” has already been enacted in 37 other states.

"She raised neither a gun nor her voice, yet ignited the 20th Century Civil Rights Movement through her courageous act of peaceful defiance. As we begin statewide observances of Black History Month, I am honored to join Assemblymember Holly Mitchell in commemorating the 100th Birthday of Rosa Parks."

Yamada Responds to State of the State
SACRAMENTO – Assemblymember Mariko Yamada (D-Davis) responded to Governor Jerry Brown’s State of the State address today:
“After years of heart-wrenching budget cuts, California is poised to stage a real recovery. I share the Governor’s ‘less is more’ vision; we cannot squander this moment in our state’s history. Working together for the common good, we should address comprehensive—not piecemeal—reform, reviewing “penny-wise, pound-foolish” program reductions that will ultimately cost the State more money.”
