Sex Offender Tier Levels: What You Need to Know
The Michigan Sex Offender Registry divides sex offenders into three different tiers or levels. These levels are called sex offender tiers, and are known as follows:
● Tier I Sex Offenders
● Tier II Sex Offenders
● Tier III Sex Offenders
If you are not familiar with these tiers or levels, here is a simple explanation of each level and how they are used for classifying sex offenders.
The tier classification all started after the Adam Walsh Act was enacted into law. This has become the standard for Michigan state police officers and authorities in classifying sex offenses.
Under the Sex Offender Registration act (SORA), Michigan sex offenses are classified based on the sex crime committed, the age of the people involved, and the likability of the person committing the same type of sex offense again.

Sex Offender Tier Levels
A minor sex offense falls under Tier 1, while the worst or most serious sex crimes fall under Tier 3 (according to SORA). To explain further, here is a list of unlawful sexual conduct crimes that can give you an overview of what classifies registered sex offenders/convicted sex offenders under Tier 1, Tier 2, and Tier 3:
