A teenager charged with the same crime can face dramatically different consequences depending on where they live.
In one state, a young person accused of a serious offense may be sent to a juvenile facility focused on treatment and rehabilitation. In another, they could face adult criminal proceedings, a permanent record and the possibility of an adult prison sentence.
This year, more than half a dozen states, including Colorado, Hawaii, Kansas, Maryland, Mississippi, Missouri and Utah, have passed new laws reshaping their juvenile legal systems. While some have adopted measures designed to divert more young people from incarceration, others have sought to impose stiffer penalties and expand prosecutors' authority to pursue adult charges.
The opposite tacks underscore an increasingly fractured approach to juvenile justice nationwide.
The new laws also come as states grapple with how to respond to serious crimes committed by children while weighing decades of research suggesting adolescents are more capable of rehabilitation than adults.
Videos of youth-involved assaults, carjackings and large gatherings sometimes called "teen takeovers" frequently spread online, fueling renewed debate over whether tougher punishments or expanded diversion programs are the better path to improving public safety.
In Hawaii, for example, a new law signed in June by Democratic Gov. Josh Green requires judges to consider a child's history of trauma before deciding whether to transfer a juvenile case to adult court. The law, which took effect immediately upon Green's signature, also prohibits minors who are victims of sex trafficking or sexual assault from being prosecuted as adults for crimes committed as a result of their exploitation.
Research suggests that incarcerating children and teens in adult prisons, where they may face lengthy sentences and restrictive conditions, can increase the risk of reoffending.
"It wasn't a question of whether kids had been traumatized, but actually how many traumas they'd experienced," said Sara Thomas, a research assistant professor of psychiatry and behavioral sciences at Northwestern University, referring to research that found young people held at the Cook County Juvenile Temporary Detention Center in Chicago had experienced a median of six traumatic events.
Colorado Democratic Gov. Jared Polis signed into law in March a measure that, when it takes effect in August, will overhaul parts of the state's youthful offender system by requiring trauma-informed care, individualized treatment plans, therapy and reentry-focused programming.
A new law in Minnesota, which also takes effect in August, will raise the minimum age at which a child can enter the juvenile justice system for an offense from 10 to 13. The change stems from legislation passed in 2024.
Once it takes effect, Minnesota will become one of only three states with a minimum age of delinquency set at 13, joining Maryland and New Hampshire, according to the National Youth Justice Network, an advocacy and research organization.
Other states are moving in the opposite direction, giving prosecutors and courts more authority to pursue adult penalties in serious cases and arguing that violent offenses require stronger consequences, regardless of a defendant's age.
In Missouri, a new law will give prosecutors more authority to seek adult charges against young people. Previously, only a juvenile officer or court could request a hearing to transfer a case to adult court. The law also narrows the offenses eligible for adult prosecution to Class A and Class B felonies, such as homicide, first-degree burglary and certain sex offenses, while requiring juvenile records and fingerprints to be added to the state's criminal history database.
"Missouri must address the revolving door for repeat violent offenders –– and that includes juveniles," Republican Gov. Mike Kehoe said in a news release.
Mississippi also expanded the circumstances under which young people can face adult charges. A new law effective this month requires 13-year-olds to automatically be tried in adult court for most violent crimes committed while possessing a firearm, even if the firearm was not used. The law prohibits children younger than 13 from being held responsible in adult court for misdemeanors or felonies, though parents or guardians may face civil liability.
A CHANGING LANDSCAPE
Beginning in the 1990s, amid concerns over violent youth crime, many states expanded laws that allowed more juveniles to be prosecuted as adults.
But as juvenile crime declined over the following decades and research on adolescent brain development grew, many states began reconsidering those policies. Research suggests that the parts of the brain involved in impulse control, decision making and evaluating long-term consequences continue developing into early adulthood.
Maryland Gov. Wes Moore signed the Youth Charging Reform Act into law in May 2026, altering how the state handles juvenile jurisdiction, detention, and confinement. The law, which goes into effect in October, limits when children younger than 13 can be charged with crimes and establishes new reporting metrics to track youth outcomes.
The new law preserves automatic adult court jurisdiction for teens 16 and older accused of offenses punishable by life imprisonment, including homicide and rape. Judges will retain the authority to transfer 14- and 15-year-olds accused of those same life-punishable offenses to adult court under the state's existing transfer procedures.
The law also tightens detention rules, requiring intake officers to authorize the detention of any child 16 or older accused of a handgun violation or violent crime. By October 2029, children will be barred from being held in adult correctional facilities.
Supporters said the changes recognize that young children who engage in delinquent behavior often have unmet mental health, educational or family needs that are better addressed through services than incarceration.
"This progress brings us closer to ensuring that hundreds of young people in Maryland are met with support and services in the juvenile system, rather than being routed into a process that leads to worse outcomes for both youth and public safety," state Democratic Sen. Will Smith Jr., the bill's primary sponsor, said in a news release.
The Maryland State's Attorneys' Association views the new law as a step backward, arguing that the state Department of Juvenile Services is not equipped to handle young people accused of violent and repeat offenses.
Baltimore City State's Attorney Ivan Bates, the association's president, also criticized the state's juvenile legal system in a post on X (formerly Twitter), calling it "broken," just weeks after a multi-jurisdictional crime ring investigation that led to charges against five teens.
"We cannot continue sending children back into a broken system and expect them to be rehabilitated while also expecting our communities to remain safe," Bates wrote.
Supporters of changes like Maryland's new law argue that adult convictions can create long-term barriers to employment, housing and education, making it harder for young people to successfully transition into adulthood. Juvenile records are generally confidential.
"Transfer of youth to adult court is bad public policy," said Mary Ann Scali, the executive director of The Gault Center, a national organization that trains and supports defense attorneys who represent young people in court. "It causes more harm and does not lead to better outcomes for young people or communities."
Sarah Johnson, senior youth defense counsel with The Gault Center, said research does not support the argument that moving children into adult court improves public safety.
"Transfer does not increase public safety. Transfer increases recidivism. Transfer traumatizes young people because they're now placed in an adult facility," Johnson said, noting that children may face heightened risks of phy
