I was wondering what does it mean to be a 1st, 2nd, or 3rd degree sex offender. Like what criteria is there for the different degrees?

The number of times committing the act.

1) First Offender.
2) Second Time Offender.
3) Repeat Offender.

The courts take great notice of this.

This gives a good definition of sexual offenses and how they are classified:

It means how dangerous for example 1st degree they don't have to notify the public 2nd is that they have to identify the public and he is moderatly dangerous 3rd is very dangerous and have to notify public as well and they are on restrictions hope this helps :)

What does it means a 4th degree sex offender and how is it address to the public n do they have to register as a sex offender
