California RDH Law & Ethics Exam Area 1C: Mandated Reporting

Patient confidentiality is a core ethical duty in dental hygiene, but California law draws hard lines where that privacy must yield to public safety. This section covers mandated reporting for child, elder, and dependent-adult abuse, which makes up 6% of the 2025 outline (the exam has 60 questions, 50 scored, in 90 minutes). Because the statutes name dental hygienists directly, the exam expects you to know exactly when your duty triggers, which agencies receive your report, and the strict deadlines you must follow.

At a glance

What the exam expects you to know

The 2025 outline tests your knowledge of mandated reporting across three specific populations. You must understand the statutory signs of abuse, the laws governing your duty, and the exact procedures for filing reports.

T9 — Reporting child abuse and neglect

California defines a "child" as a person under 18 years of age.⁵ The Child Abuse and Neglect Reporting Act (CANRA) defines abuse and neglect in specific categories: physical injury inflicted by other than accidental means, sexual abuse, neglect, willful harming or endangering, and unlawful corporal punishment.⁵ Neglect is further divided into "severe neglect" (such as failure to protect a child from severe malnutrition) and "general neglect" (negligent failure to provide adequate food, clothing, shelter, or medical care).⁵ The statute includes specific carve-outs: a mutual affray (fight) between minors is not child abuse ⁵, a minor's pregnancy alone does not constitute reasonable suspicion of sexual abuse ⁴, and general neglect does not include a parent's economic disadvantage.²

You are personally a mandated reporter. Penal Code § 11165.7(a)(21) lists the "dental hygienist" by name.² Your duty triggers whenever, in your professional capacity, you have knowledge of or observe a child whom you know or reasonably suspect has been the victim of child abuse or neglect.⁴ "Reasonable suspicion" is an objective standard based on your training and experience; it expressly does not require certainty or a specific medical indication.⁴

The filing procedure is a strict two-step process. First, you must make an initial report by telephone "immediately or as soon as is practicably possible." Second, you must prepare and send, fax, or electronically transmit a written followup report within 36 hours of receiving the information.⁴ The report must go to a police or sheriff's department (excluding school district police), a designated county probation department, or the county welfare department.⁵ The reporting duty is individual: when you and another mandated reporter share knowledge, you may agree that one of you files a single team report, but if that person does not report, you must. No supervisor may impede your report, and telling a supervisor is never a substitute for the agency report; internal procedures may only help you report.⁴

T10 — Reporting dependent adult abuse

A "dependent adult" is a person between 18 and 64 years of age who has physical or mental limitations that restrict their ability to carry out normal activities or protect their rights, or any 18-to-64-year-old admitted as an inpatient to a 24-hour health facility.^{3 5} The Elder Abuse and Dependent Adult Civil Protection Act defines abuse to include physical abuse, neglect, abandonment, isolation, abduction, and financial abuse.^{3 5}

Under Welfare & Institutions Code § 15630(a), you are a mandated reporter because the statutory definition of a "health practitioner" (§ 15610.37) expressly includes the dental hygienist.^{3 5} The duty triggers when you observe, have knowledge of, or reasonably suspect physical abuse, abandonment, abduction, isolation, financial abuse, or neglect. It also triggers if the dependent adult tells you they have experienced such behavior.³ These six categories require a mandatory report; reporting other types of emotional mistreatment is voluntary.³

The filing procedure depends on the setting. For abuse occurring in a private dental office, a private home, or a community setting, you must report to the adult protective services agency or the local law enforcement agency. The initial report is made by telephone or through a confidential internet reporting tool immediately or as soon as practicably possible. If the initial report was by telephone, a written report must be sent within two working days.^{3 5}

T11 — Reporting older adult abuse

An "elder" is defined simply as any person residing in California who is 65 years of age or older.^{3 5} Unlike a dependent adult, an elder requires no physical or mental limitation to be protected under the statute. A fully independent 66-year-old is an elder, and reasonable suspicion of their abuse triggers the same mandatory reporting duty.³ The categories of abuse are identical to those for dependent adults.^{3 5}

The reporting laws, triggers, and penalties for elders are the same as for dependent adults. Failing to report is a misdemeanor punishable by up to six months in county jail, a fine of up to $1,000, or both. If the willful failure involves abuse that results in death or great bodily injury, the penalty escalates to up to one year in county jail, a fine of up to $5,000, or both.^{3 5} In exchange for this strict duty, confidentiality laws yield to this compelled disclosure.^{6 5}

When elder or dependent-adult abuse occurs inside a long-term care facility, the filing procedure accelerates. If the abuse was allegedly caused by another resident with physician-diagnosed dementia and there was no serious bodily injury, you must submit a written report within 24 hours to the long-term care ombudsman and local law enforcement.^{3 5} In all other facility instances, you must make a verbal report to local law enforcement immediately or as soon as practically possible, but no longer than two hours. This is followed by written reports within 24 hours to the ombudsman, local law enforcement, and the corresponding state licensing agency.^{3 5}

Common traps

• Telling the dentist and stopping there. Reporting to an employer, supervisor, or coworker is never a substitute for the mandated report. No supervisor may impede your report, and telling a supervisor is never a substitute for the agency report; internal procedures may only help you report.⁴
• Waiting for proof or a diagnosis. Any reasonable suspicion is sufficient. The statutes explicitly state that certainty and specific medical indications are not required.⁴
• Swapping the clocks. Child abuse requires a written followup within 36 hours. Elder and dependent-adult abuse requires a written followup within two working days. Long-term care facility cases use 2-hour verbal and 24-hour written lanes.^{4 3}
• Reporting to the wrong agency. Child reports go to police, sheriff, designated county probation, or county welfare. They do not go to the Dental Hygiene Board of California, nor do they go to a school security department.⁵
• Fearing a confidentiality violation. Medical information is confidential by default, but the Confidentiality of Medical Information Act yields to disclosures compelled by law. Mandated reporters have no civil or criminal liability for required or authorized child-abuse reports (Penal Code §11172), and privilege does not apply to reported information.^{6 5}
• Treating a minor's pregnancy as automatic abuse. A minor's pregnancy does not, in and of itself, constitute a basis for a reasonable suspicion of sexual abuse.⁴

How to study this area

Mandated reporting accounts for 6% of the 2025 outline (the exam has 60 questions, 50 scored, in 90 minutes). While the weight is relatively small, the rules are rigid and highly specific. Do not rely on general workplace compliance training; rely on the exact statutory definitions and timelines in the statutes (Penal Code §§11164 et seq.; WIC §§15610 and 15630).

Focus your study time on distinguishing the three populations and their respective clocks. Create a mental grid: under 18 goes to CANRA (36 hours); 18 to 64 with limitations goes to dependent adult (two working days); 65 and older goes to elder (two working days, or the 2-hour/24-hour facility fast lanes).

1. Memorize the clocks. Know the difference between 36 hours, two working days, and the 2-hour/24-hour facility rules.
2. Know the age brackets. Remember that 65 makes an elder automatically, but an adult under 65 must have a qualifying limitation to be a dependent adult.
3. Remember the individual duty and the team-report exception. The duty is individual. Telling your employer is not a substitute for a report to the proper agency (§11166(i)(3)). If you and another mandated reporter, such as the dentist, jointly know or suspect the abuse, you may agree that one of you files a single team report, but if that person doesn't file, you must.

Questions candidates ask

Do I need to be certain before I file a report?

No. The legal standard is "reasonable suspicion," which is measured by what a reasonable person in your position, drawing on your training and experience, would suspect. The law expressly states that certainty is not required.⁴

Can I just tell my supervising dentist and let them handle it?

The duty is individual. Telling your employer is not a substitute for a report to the proper agency (§11166(i)(3)). If you and another mandated reporter, such as the dentist, jointly know or suspect the abuse, you may agree that one of you files a single team report, but if that person doesn't file, you must.⁴

What happens if I fail to report suspected abuse?

Failing to report is a misdemeanor punishable by up to six months in county jail, a fine of up to $1,000, or both. If the willful failure involves abuse that results in death or great bodily injury, the penalty increases to up to one year in jail, a $5,000 fine, or both.^{4 3}

Does HIPAA or patient confidentiality prevent me from reporting?

No. California's Confidentiality of Medical Information Act (CMIA) and federal privacy rules permit disclosures that are required by law. Furthermore, mandated reporters have no civil or criminal liability for required or authorized child-abuse reports (Penal Code §11172).^{6 7 5}
