Child Discipline Laws in Washington State: Limits, CPS, and Charges

Washington lets parents and guardians use physical force to discipline a child, but only when that force is “reasonable and moderate.” That standard comes from RCW 9A.16.100, and child discipline laws in Washington state treat anything beyond it as assault.¹ The statute lists specific acts that are presumed unlawful, and crossing that line can trigger a CPS investigation, felony charges, or both.

What “Reasonable and Moderate” Actually Means

RCW 9A.16.100 creates a legal defense for a parent or guardian who uses physical force to restrain or correct a child. Without that defense, deliberate physical contact that causes pain would qualify as assault.¹

Whether force was reasonable and moderate is decided on objective circumstances: the child’s age, size, and physical or mental condition, and where on the body any injury occurred.¹ A swat that could be moderate for a twelve-year-old may be unreasonable for a toddler. The force also has to serve a corrective purpose. Hitting a child out of frustration or anger, rather than to correct behavior, falls outside the defense no matter how light it is.

Acts That Are Presumed Unlawful

The statute names specific acts that are presumed unreasonable when used on a child:¹

Throwing, kicking, burning, or cutting a child
Striking with a closed fist
Shaking a child under age three
Interfering with breathing
Threatening with a deadly weapon
Any act likely to cause, and that does cause, bodily harm greater than brief pain or minor temporary marks

The last item is the catch-all and the one that matters most in practice. If discipline leaves bruises, welts, cuts, or any mark that doesn’t fade quickly, courts will presume it was unreasonable. The list is illustrative, not exhaustive; an act not on it can still be found unreasonable based on the circumstances.

Using an object to strike a child isn’t singled out by name, but it’s a serious risk factor. Belts, switches, and similar implements are far more likely to leave marks beyond brief redness, which pushes the act into the presumptively unreasonable column. Open-hand spanking that leaves no lasting marks has the strongest chance of falling within the defense, and even that depends on the child’s age, size, and where the contact lands.

Babysitters, Relatives, and Other Non-Parents

A babysitter, relative, or other non-parent caregiver has no independent authority to physically discipline a child. Under RCW 9A.16.100, a non-parent may use reasonable and moderate force only if the child’s parent or guardian authorized it in advance.¹ Without that prior authorization, any use of force by a caregiver is unlawful. Even with it, the same standard and the same presumptions of unreasonableness apply.

Schools, Childcare, and Foster Care

The parental privilege does not follow a child into institutional care. Washington bans corporal punishment in all public schools, and no district employee or contractor may inflict physical pain on a student as discipline.² Staff may use reasonable physical force only to maintain order or prevent a student from harming themselves, other students, staff, or property.

Licensed childcare providers face stricter rules still. State regulations prohibit corporal punishment of any kind, including spanking, along with verbal abuse, shaming, threats, and any discipline designed to cause fear or humiliation. Withholding food, forcing food, or restricting bathroom access as punishment is also forbidden.

Foster care follows the same principle. DCYF rules prohibit physical punishment, cursing, threats, intimidation, and any discipline that interferes with a child’s basic needs.³

What Happens if Discipline Crosses the Line

CPS Investigation

When discipline is reported as possible abuse, Child Protective Services can open a civil investigation. Caseworkers can interview a child at school, daycare, or anywhere else suitable, without parental permission or advance notice. If a report alleges immediate danger, CPS must begin investigating within 24 hours. The agency has up to 90 days from the date of the report to finish.⁴

If CPS concludes abuse occurred, it issues a “founded” finding and can put a safety plan in place, which may restrict a parent’s contact with the child. In more serious cases, CPS can file a dependency petition asking a judge to take jurisdiction over the child’s welfare. That can lead to foster placement while the parent completes services such as parenting classes or counseling.

Teachers, doctors, nurses, counselors, law enforcement, childcare workers, clergy, and DCYF employees are among Washington’s mandatory reporters, and they must report suspected abuse or neglect within 48 hours of having reasonable cause.⁵

Criminal Charges

Unlawful discipline can also draw criminal charges, on a track separate from CPS. Washington’s assault-of-a-child statutes apply when the accused is 18 or older and the victim is under 13:

Assault of a child in the third degree, a Class C felony, carries up to five years in prison and a $10,000 fine.⁶⁷
Assault of a child in the second degree, a Class B felony, applies when someone intentionally assaults a child under 13 and causes harm beyond brief pain or minor marks, combined with a prior pattern of assaultive behavior or pain equivalent to torture. It carries up to 10 years and a $20,000 fine.⁸⁷
Assault of a child in the first degree, a Class A felony, covers intentional assaults on a child under 13 that recklessly cause great bodily harm, or a pattern of conduct resulting in substantial bodily harm or pain equivalent to torture. It carries up to life in prison and a $50,000 fine.⁹⁷

These child-specific charges require the victim to be under 13. When the child is 13 or older, prosecutors can still bring standard assault charges, but without the child-specific enhancements or their steeper penalties.

Your Rights if You Are Investigated

If a dependency petition is filed, you have the right to a lawyer. If you can’t afford one, the court appoints one at no cost once you request it. You can attend every hearing, hear the evidence against you, present your own evidence, and question witnesses. The judge must decide based solely on what’s presented.¹⁰ You are also entitled to view and copy the records DCYF plans to use, at no cost. If you skip a hearing, the judge will proceed without your input.

A criminal case runs on its own track alongside the CPS case, and statements made in either process can be used in the other. Talking to a lawyer before making detailed statements to a caseworker or an officer is one of the more consequential choices a parent in this position can make.
