A more thorough explanation:

Grading is the process of determining the level of seriousness of a criminal offense. This is usually done by assigning a degree or class to the offense.

For example, a felony may be graded as first degree, second degree, or third degree, depending on the severity of the crime. Similarly, a misdemeanor may be graded as Class A, Class B, or Class C.

For instance, if someone is convicted of first-degree murder, it means that the crime was premeditated and intentional, and the punishment will be more severe than if they were convicted of second-degree murder, which may have been a crime of passion or impulse.

Another example is a Class A misdemeanor, such as assault with a deadly weapon, which is more serious than a Class C misdemeanor, such as disorderly conduct.

Grading helps to ensure that the punishment fits the crime and that similar offenses are treated similarly. It also helps to guide judges and juries in determining appropriate sentences.
