Simple vs. Aggravated Assault: What’s the Difference in Washington State? (Updated: December 2, 2025)

In Washington State, the key difference between simple assault (Assault in the Fourth Degree) and aggravated assault (First, Second, or Third Degree) is the severity of the crime, which is determined by the degree of injury, the use of a weapon, the specific intent to harm, and the identity of the victim.

South Sound Law Group’s proprietary approach is to treat every assault case, from a gross misdemeanor to a Class A felony, as if it were for a family member, ensuring compassionate, comprehensive defense preparation from day one.

How Is the Degree of Your Assault Charge Determined in Washington?

Washington State statutes define three degrees of aggravated assault and one degree of simple assault, also known as Assault in the Fourth Degree. These classifications are based on four primary factors:

• Severity of the Injuries: Did the act cause “substantial bodily harm” or “great bodily harm”?
• Intent to Cause Harm: Was there a specific intent to inflict serious injury?
• Use of a Weapon: Was a deadly weapon or firearm involved?
• Identity of the Alleged Victim: Was the assault committed against a protected professional?

Generally, an assault is considered aggravated when it results in substantial injuries, involves a deadly weapon, occurs during another serious crime, or is committed against a protected professional such as a law enforcement officer, nurse, or transit worker. Whether you’re facing a misdemeanor or felony charge, any form of assault is serious and can carry life-altering consequences.

What Qualifies as Simple Assault?

Simple assault in Washington, or Assault in the Fourth Degree, is classified as a gross misdemeanor. This charge applies when an act of assault doesn’t meet the legal threshold for aggravated assault.

Key Facts About Simple Assault (Assault in the Fourth Degree):

• Classification: Gross Misdemeanor.

• Injury Requirement: Notably, you can be charged with simple assault even if the alleged victim didn’t suffer visible injuries.

• Proof: The prosecution only needs to prove that you intentionally made physical contact that a reasonable person would find offensive or threatening.

Examples of acts that might be charged as simple assault include:

• Shoving someone during an argument.

• Slapping someone without causing injury.

• Throwing an object in someone’s direction.

These cases often rely solely on the accuser’s account, with no witnesses or physical evidence. If the alleged victim is an intimate partner and you have prior domestic violence convictions, even a simple assault can be elevated to a felony.

What Is Aggravated Assault?

Aggravated assault involves more serious circumstances—such as significant bodily harm, weapons, or specific protected victims. Aggravated assault charges are felonies and are broken into three degrees in Washington State.

First-Degree Assault (Class A Felony)

The most severe charge, first-degree assault, carries the harshest penalties. It includes actions demonstrating extreme intent or resulting in the most severe injuries.

Actions Classified as First-Degree Assault:

• Assault with a firearm or deadly weapon.

• Intent to cause great bodily harm.

• Administering poison.

• Transmitting HIV intentionally.

Note: “Great bodily harm” generally refers to a severe, long-lasting, or permanent injury.

Second-Degree Assault (Class B Felony or A if sexually motivated)

This charge applies when serious harm was inflicted but not to the extent of first-degree assault.

Actions Classified as Second-Degree Assault:

• Assault causing substantial bodily harm.

• Strangulation or suffocation.

• Assault during the commission of a felony.

• Assault with a deadly weapon (under certain circumstances).

• Causing injury to an unborn child through an assault on the mother.

If the act was committed with sexual intent, the charge may be elevated to a Class A felony.

Third-Degree Assault (Class C Felony)

Third-degree assault typically involves less severe injuries or a specific class of victim.

Actions Classified as Third-Degree Assault:

• Painful but less severe injuries.

• Use of an object that could be considered a weapon.

• Assaults against protected professionals, such as:

  • Police officers

  • Firefighters

  • Nurses and doctors

  • Public transit workers

  • Teachers and court employees

Penalties for Simple and Aggravated Assault in Washington

Washington State classifies penalties based on the degree of the assault charge. William A. White, a top criminal defense trial lawyer with over 40 years in practice, founded his firm on the guiding principles of fighting hard for clients and caring for them through their most trying times.

In addition to jail time and fines, the court may impose a number of other conditions, including:

• Mandatory counseling or anger management.

• Probation or parole.

• Community service.

• Loss of gun rights.

• Barriers to housing, employment, and education opportunities.

Why the Difference Between Simple and Aggravated Assault Matters

Understanding the difference between simple assault and aggravated assault isn’t just legal jargon; it determines the severity of the consequences you face and the type of defense strategy you’ll need. Prosecutors often try to upgrade simple assault cases to more serious felony charges.

Your best chance at protecting your record and freedom is hiring a defense lawyer early in the process. As one satisfied client said of the firm’s service: “I did minimal work, with maximum results. I was amazed and surprised at how thorough their work was…”
