Washington state uses the term "Assault" for all criminal charges involving use of force or even threats of force. Washington classifies Assault charges by degree - 1st degree being the highest/most serious, 4th degree being the lowest. All assault/physical harm offenses are set out in RCW 9A.36. Washington state does not specifically use the term "Aggravated Assault," although there are factors that could be added on to the assault charge that could be termed "aggravating factors" (such as use of a deadly weapon during the assault). These aggravating factors can be used to enhance the sentence of a person who is convicted. There is no Washington state criminal law for the crime of "Battery."
