A juvenile convicted of attempted murder can face anything from a rehabilitative placement in juvenile court to a lengthy adult prison term, but one outcome is off the table: the U.S. Supreme Court has categorically barred life without parole for any offender under 18 convicted of a non-homicide offense, and attempted murder qualifies as non-homicide no matter how severe the injuries.1Legal Information Institute. Graham v. Florida The actual juvenile sentence for attempted murder turns almost entirely on one question: does the case stay in juvenile court, or does it get transferred to adult court? That single procedural decision reshapes the length of confinement, the type of facility, and whether the record can ever be sealed.
If the Case Stays in Juvenile Court
Juvenile court sentencing is called disposition, and it is built around rehabilitation rather than punishment.2Legal Information Institute. Parens Patriae For attempted murder, dispositions tend to cluster at the more restrictive end of what juvenile courts can order, but the goal is still to get the juvenile back on track before adulthood.
Common dispositions for a serious violent offense include:
- Secure confinement in a locked juvenile facility, often until the offender reaches the age of majority or the state’s extended jurisdiction age.
- Residential treatment that combines confinement with therapy for mental health, substance abuse, or behavioral issues.
- Intensive probation with curfews, regular check-ins, counseling, and electronic monitoring.
- Restitution to the victim for medical costs and other financial harm.
For attempted murder, secure confinement paired with mandatory treatment is the most likely outcome. Judges rely heavily on probation officer reports and psychological evaluations before deciding.
How long confinement can last depends on each state’s extended jurisdiction rules. Many states hold authority over a juvenile case until age 21. California, Montana, Oregon, and Wisconsin extend juvenile jurisdiction to age 24. Colorado, Connecticut, Hawaii, and New Jersey allow jurisdiction to continue for the full term of the disposition order with no fixed age cutoff.3Office of Juvenile Justice and Delinquency Prevention. Age Boundaries of the Juvenile Justice System Once that ceiling hits, the juvenile court loses authority, which is the main reason prosecutors push to move serious cases to adult court in the first place.
One more thing matters here. A juvenile court outcome is an adjudication of delinquency, not a criminal conviction. In most states that is a real legal distinction, not just a label, and it affects how the record is treated afterward.
If the Case Is Transferred to Adult Court
Transfer to adult court is the single highest-stakes decision in a juvenile attempted murder case. In adult court, the juvenile faces adult sentencing guidelines, adult prison exposure, and a permanent criminal record. Research on transferred juveniles found that roughly 73 percent end up incarcerated in prison or jail, though many are released by age 21.4Office of Juvenile Justice and Delinquency Prevention. Transfer of Juveniles to Adult Court – Effects of a Broad Policy in One Court
There are three routes into adult court:
- Judicial waiver, where a juvenile court judge holds a hearing and decides whether to send the case up. This is the most common method and is available in 46 states.5Office of Juvenile Justice and Delinquency Prevention. Trying Juveniles as Adults in Criminal Court – An Analysis of State Transfer Provisions
- Statutory exclusion, where the legislature has already placed certain offense-and-age combinations directly in adult court, bypassing juvenile court entirely.6Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court
- Direct file, where the prosecutor files charges in adult court without a judge making the transfer decision.6Office of Juvenile Justice and Delinquency Prevention. Juvenile Transfer to Criminal Court
At a waiver hearing, the judge works through the factors set out in Kent v. United States: the seriousness of the offense, whether it was violent or premeditated, the juvenile’s maturity and home environment, prior delinquency history, and the likelihood of rehabilitation through the juvenile system.7Justia U.S. Supreme Court Center. Kent v. United States, 383 U.S. 541 (1966) Both sides present evidence, and the hearing often turns on psychological evaluations and background reports.5Office of Juvenile Justice and Delinquency Prevention. Trying Juveniles as Adults in Criminal Court – An Analysis of State Transfer Provisions The difference between winning and losing that hearing can be the difference between a disposition that ends at 21 and a prison sentence stretching decades.
If the case ended up in adult court through statutory exclusion or direct file, the door is not necessarily closed. Twenty-three states allow a juvenile prosecuted as an adult to petition the criminal court to send the case back to juvenile court, a procedure known as reverse waiver.8Office of Juvenile Justice and Delinquency Prevention. Reverse Waiver Success turns on many of the same factors used in a forward waiver.
Blended Sentencing: The Middle Path
Some states give courts a hybrid option. Under blended sentencing, the judge imposes a juvenile disposition and an adult sentence at the same time, with the adult sentence suspended. If the juvenile completes the juvenile disposition and stays out of trouble, the adult sentence is dismissed. If the juvenile violates conditions or reoffends, the adult sentence takes effect.9Office of Juvenile Justice and Delinquency Prevention. Sentencing Authority
For attempted murder, blended sentencing can mean a rehabilitative placement with a prison term hanging overhead as leverage. In adult criminal courts, judges in about 12 states have authority to impose juvenile-style sanctions on younger offenders convicted of less serious crimes.9Office of Juvenile Justice and Delinquency Prevention.

The Constitutional Ceiling on Juvenile Sentences
Regardless of which court hears the case, a line of Supreme Court decisions sets hard limits on what any juvenile can be sentenced to. Graham v. Florida (2010) is the controlling case for attempted murder specifically. It holds that sentencing anyone under 18 to life without parole for a non-homicide offense violates the Eighth Amendment.1Legal Information Institute. Graham v. Florida A juvenile convicted of attempted murder must have a realistic opportunity for release at some point, and courts cannot impose a term of years so extreme that it functions as a de facto life sentence.
Two related decisions fill in the surrounding framework. Roper v. Simmons (2005) bars the death penalty for anyone who was under 18 at the time of the offense.10Justia U.S. Supreme Court Center. Roper v. Simmons, 543 U.S. 551 (2005) Miller v. Alabama (2012) bars mandatory life without parole for juveniles even in homicide cases and requires sentencing courts to consider the juvenile’s age, home environment, offense circumstances, and rehabilitation potential.11Justia U.S. Supreme Court Center. Miller v. Alabama, 567 U.S. 460 (2012) Montgomery v. Louisiana (2016) made Miller retroactive, opening the door to resentencing for juveniles sentenced under earlier mandatory LWOP schemes.12Justia U.S. Supreme Court Center. Montgomery v. Louisiana, 577 U.S. 190 (2016)
For an attempted murder case, Graham is the one that does the heaviest lifting. Even after a transfer to adult court and a conviction, the sentence must leave a meaningful chance at release.
What Judges Weigh When Setting the Sentence
Two juveniles charged with attempted murder rarely receive identical sentences. The variables courts consider most heavily:
Age at the time of the offense. A 13-year-old is generally viewed as far more amenable to rehabilitation than a 17-year-old. The Supreme Court in Miller identified adolescent immaturity, impulsivity, and susceptibility to peer pressure as features of youth that reduce culpability.11Justia U.S. Supreme Court Center. Miller v. Alabama, 567 U.S. 460 (2012)
Prior delinquency history. A first-time offender is in a stronger position than a juvenile with a pattern of escalating violence. Courts read prior record as a signal of whether the offense was a one-time failure or an entrenched pattern.
Home environment and family circumstances. Miller requires judges to account for family circumstances the child could not control. A chaotic or abusive home can soften the disposition; a stable family with real support may make a community-based option viable.
Psychological evaluations. These are nearly universal in attempted murder cases. Courts want to know whether a mental health condition contributed to the offense, whether the juvenile shows remorse, and how they respond to treatment.
Circumstances of the offense. A planned, premeditated attack is treated far more seriously than a spontaneous act during an emotional crisis. Whether the juvenile acted alone or under the influence of older co-defendants matters, since the Supreme Court has repeatedly recognized adolescent vulnerability to peer pressure.
Victim impact. Victims and their families have a right to describe the physical, emotional, and financial harm they suffered, and judges use that information when setting restitution and considering stricter conditions.13Department of Justice. Victim Impact Statements In attempted murder cases, where injuries are often severe, this testimony can carry real weight.
Long-Term Consequences of the Sentence
What happens after the sentence matters almost as much as the sentence itself, and here the juvenile court versus adult court divide shows up again.
A juvenile court outcome is an adjudication of delinquency, not a criminal conviction, in most states. That means the juvenile can generally answer “no” when asked on job applications whether they have been convicted of a crime. The adjudication can still be considered in future proceedings, and serious adjudications like attempted murder carry more lasting consequences than minor ones, but the distinction preserves voting rights in most states and reduces barriers to employment.
An adult court conviction is different. It is public, permanent, and carries the full collateral consequences of any adult felony, including restrictions on housing, employment, and civil rights that can last a lifetime.
Record sealing follows the same divide. Most states impose significant restrictions on sealing records for serious violent offenses, and some explicitly exclude crimes like attempted murder from eligibility. Others require a waiting period after the disposition ends, followed by a petition and a showing of rehabilitation. A few states automatically seal certain juvenile records at 18 or 21, but automatic sealing rarely reaches violent felonies. Even where sealing is possible, law enforcement often retains access, and some states permit public access to juvenile records involving serious bodily harm or death.14Office of Juvenile Justice and Delinquency Prevention. Expunging Juvenile Records – Misconceptions, Collateral Consequences, and Emerging Practices If the case went to adult court, the conviction follows adult record rules, which generally offer none of the protections juvenile records receive.
The practical takeaway is straightforward. For a juvenile charged with attempted murder, the fight over which court hears the case is often the most consequential part of the proceeding. The constitution guarantees a path back to release. Everything else, from the length of confinement to whether the record ever disappears, depends on the choices made long before any sentence is pronounced.
