The NBA and USA Basketball have partnered to develop guidelines designed to promote a positive and healthy youth basketball experience.


About These Guidelines

Basketball is a great game that is played by millions of young people in the United States and around the world. Playing basketball fosters the development of peer relationships, self-esteem, leadership qualities, and physical health.

To date, however, the sport of basketball has lacked guidelines around health and wellness and consistent game play standards. To help foster player health, age- and stage-appropriate skill development, and a positive and enjoyable on-court experience for young people, the NBA and USA Basketball have developed a set of rules and standards to enhance the playing experience for young athletes. 

These guidelines aim to combat the overemphasis on early competitive success and the lack of a clear development pathway through the sport – two issues that exist across youth sports, including basketball.

The NBA and USA Basketball are committed to helping shape a youth basketball environment that prioritizes the health and well-being of young athletes and promotes their enjoyment and development in the game.


Health and Wellness

Participation Guidelines

Overscheduling of competitive events, overuse injuries and burnout have become too common in youth basketball.  The tables below outline recommended and maximum amounts of youth basketball participation, as well as rest guidelines for young athletes, designed to promote a fun and healthy playing experience.

Age Game Length # of Games Per Week Practice Length # of Practices Per Week
Ages 7-8 20-28 min 1 30-60 min 1
Ages 9-11 24-32 min 1 to 2 45-75 min 2
Ages 12-14 28-32 min 2 60-90 min 2 to 4
Grades 9-12 32-40 min 2 to 3 90-120 min 3 to 4

Maximum Participation Guidelines

Age # of Games Per Day # of Hrs. Per Week in Organized Basketball
Ages 7-8 1 3 hours
Ages 9-11 2* 5 hours
Ages 12-14 2* 10 hours**
Grades 9-12 2* 14 hours

The maximum participation guidelines outlined above and guidance on camps and academies below are intended to serve as limits on a young athlete’s participation in organized basketball. It is possible that participation in organized basketball within the maximum limits but in excess of the recommendations is also not advisable from a health and wellness standpoint; however, this issue requires further study.

*Youth basketball players, parents, and coaches should demonstrate caution in scheduling or participating in more than one game per day, especially on consecutive days. If young athletes participate in an event or tournament in which more than one game is played per day on consecutive days, players should have additional time off from sports activities following the event to allow for recovery.

**It is recommended that young athletes in these age ranges who are approaching the maximum hour limits not participate in another organized sport concurrently.

Rest Guidelines

Age Min. # of Rest Days Per Week Max. Months Per Year in Organized Basketball Recommended Hours of Sleep Per Night
Ages 7-8 2 4 months 9-12 hours
Ages 9-11 2 5 months 9-12 hours
Ages 12-14 1 7 months 8-10 hours*
Grades 9-12 1 9-10 months 8-10 hours

*For 12 year olds, 9-12 hours of sleep is recommended.

Definition of Organized Basketball

Organized basketball includes game competition as well as practice time and structured training in which an athlete works in a focused way (typically with or at the direction of a coach) to improve his or her game. Unstructured individual or peer-led time oncourt DOES NOT constitute organized basketball for the purpose of this table (e.g., pickup games, a player individually shooting baskets by himself/herself, a player working with a peer to practice a skill).

Youth Basketball Camps and Academies

Participation in a youth basketball camp or academy can result in a young athlete exceeding maximum weekly participation guidelines.

Camp program content and duration is variable, and youth basketball camps can be a positive experience for young athletes even in cases where they exceed the guidelines above. Camp directors should, however, keep the guidelines above in mind and seek to include activities other than organized oncourt basketball participation, particularly for longer-duration camps. We recommend additional rest for young athletes following camp attendance to allow for recovery prior to resuming organized basketball sessions or attendance at another camp.

Youth sports academies that provide more comprehensive training experiences for young athletes also exist, particularly outside the United States. As with camps, the curriculum, training protocols and health and wellness resources at academies are also variable. To an even greater degree than camps, a significant portion of a basketball academy’s physical curriculum should involve activities other than organized basketball participation, which can include self-directed or peer-led basketball practice or play, or non-basketball sport and training activities. This is particularly true for academies that include athletes that have not yet reached the ninth grade.

Camps and academies should recognize that there is a lack of evidence to support early single-sport specialization. The overall effects on the health and well-being of young athletes of longer-duration camps and youth academies require further study.

Sports Specialization

Recommendation: Delay specialization in basketball until at least age 14.

Playing multiple sports helps kids make new friends and develop new skills.  Medical and scientific experts recommend early sports sampling and delaying single-sport specialization until mid to late adolescence.  Playing multiple sports should not be viewed as falling behind, but rather as building the foundation for future success.  Research shows that early sport specialization is NOT necessary to produce elite-level performance.

Sports Sampling

Sports sampling, which is characterized by participation in multiple sports during childhood, provides a young athlete the chance to find a sport that may ultimately fit him or her best.  There are several demonstrated benefits of sports sampling:

  • Prolonged engagement in sports
  • More enjoyable and positive early sports experiences
  • Healthy physical, psychological, and social development
  • Transfer of skills acquired from multiple sports to primary sport if specialization occurs

Current research does not support the view that early single-sport specialization is either necessary or sufficient to produce elite performance at advanced levels of competition. In fact, early single-sport specialization in basketball and other team sports may be detrimental to long-term elite performance.

Athletes that reach the highest level of achievement have been shown to be more likely to have played multiple sports at a young age compared to athletes that reach relatively lower levels of achievement. With respect to basketball and other similar ball sports, world-class athletes often delayed single-sport specialization until age 16 or later.

Summary Recommendations

Based upon the scientific literature and the consensus of our Health and Wellness Working Group, the NBA and USA Basketball recommend the following for young athletes, parents and basketball organizations:

1. Promote personal engagement in youth basketball and other sports.

Sports provide opportunities for children and adolescents to connect with others, build meaningful relationships and take on challenges and leadership roles that promote overall personal development and well-being.

2. Youth sports should include both organized and informal, peer-led activities.

Peer-led activities allow children freedom to create and challenge themselves. In addition to having structured practices and competitions, basketball organizations should encourage informal, peer-led opportunities for individual growth.

3. Youth should participate in a variety of sports.

Sport sampling during childhood provides a foundation for long-term success, often by allowing young athletes a chance to find a sport that they enjoy and that may ultimately fit them best. For the sport of basketball, multi-sport participation in youth can help an athlete be a better basketball player.

4. Delay single-sport specialization in the sport of basketball until age 14 or older.

Participation in multiple sports in early childhood is beneficial from a player health and player development perspective. Athletes that reach the highest level of achievement are more likely to have played multiple sports at a young age and delayed single-sport specialization until late adolescence.

Studies of world-class athletes in basketball and other team ball sports have demonstrated that top performing athletes often delayed single-sport specialization until age 16 or later. Thus, delaying specialization until this age range is recommended. However, when considering the need to balance time among school, sports, community activities, and other responsibilities, our experts recognize that single-sport specialization in the U.S. may occur upon entry to high school. Specialization in basketball prior to age 14 is discouraged.

5. Ensure rest from organized basketball at least one day per week, and extended time away from organized basketball each year.

Daily rest is important for injury prevention, sport development and overall health. Rest days should be taken each week, and extended time off should be taken each year for physical recovery as well as to recharge oneself psychologically. Such an approach helps to maintain motivation for continued participation.

6. Limit high-density scheduling based on age-appropriate guidelines.

High-density competition scheduling can increase risk for injury and burnout. Parents, coaches and event directors should be cautious in considering tournaments that schedule multiple competitive events (i.e., games) in short periods of time. Special attention must be paid to rest, recovery and refueling.

7. Further evaluation of basketball-specific neuromuscular injury prevention training program is warranted.

Such programs appear valuable in reducing lower extremity injuries in other sports. Early results indicate similar benefits in basketball.

8. Parents and coaches should be educated regarding concepts of sport readiness and injury prevention.

Variations among youth in cognitive and social development, as well as motor skills, should be considered when setting goals and expectations.


Player Segmentation

The NBA and USA Basketball have adopted a Youth Basketball Player Segmentation Model designed to help ensure player safety, consistency and competitive fairness and balance for youth basketball players. 

This player segmentation model, developed by an expert working group on Playing Standards, has a hybrid age/grade structure that employs strict age groupings through age 13, followed by a grade affiliation model once a player enters the ninth grade.  The following are key elements of the model:

Age-based segmentation through age 13

• For purposes of eligibility, a “Playing Year” is defined as Sept. 1-Aug. 31.

• Beginning at age six, players are segmented by single-year age through age 13. Date of birth relative to the Playing Year is the final determinant of eligibility.

• For age segments, each age designation reflects the maximum age of a player during the Playing Year. For example, using the 2021-22 Playing Year, the 12U segment is for players who are 12 years of age and under as of Aug. 31, 2022. Should a player turn 13 on Aug. 31 or earlier, the player would be ineligible for the 12U segment and would be considered a 13U player.

14U or 8th grade - transition year

• A transition year between age-based and grade-based affiliation is necessary to allow for players who have been held back in school or are old for their grade. This provides a transition period from playing with one’s age segment to playing with kids in the same academic grade.
• Event operators have the option to host a division based on the 14U age-based model and/or adopt the 8th grade-based model.

Grade-based segmentation in grades 9 through 12

• Players in grades nine through 12 are classified based on the grade they are attending in school as of Oct. 1 of the Playing Year.

• Exceptions: For grade segments only, players must be enrolled in school at the grade level in which they are competing AND can only be up to one Playing Year older than their grade indicates. For example, using the 2021-22 Playing Year, a ninth grade player cannot turn 17 prior to Sept. 1, 2022.

2021-22 Player Segmentation Reference Guide

Developmentally-Appropriate Playing Guidelines

The NBA and USA Basketball working group on Playing Standards is developing age- and stage- appropriate playing guidelines – to include playing rules, equipment recommendations, and competition structure elements – for four age groupings:

  • 8 and under
  • 9-11 years old
  • 12-14 years old
  • Grades 9-12

These recommendations, which will be announced in 2017, are being designed to provide developmentally appropriate standards for youth basketball – allowing the game to evolve as kids grow and mature.


Rules & Standards


Basketball is played in countless settings and locations across the U.S. –  and though the game remains fundamentally the same, there are many variables that can impact a young player’s experience.  The NBA and USA Basketball want all players to enjoy the game and have a fun, developmentally appropriate experience.

Parents and coaches frequently ask certain questions, especially when their kids are young:

  • How high should we set the basket?
  • What size ball should we use?
  • Should we play zone defense?

These are important questions, and we understand that playing with the correct equipment and establishing age-appropriate rules significantly impacts the experience for youth as they learn the game.  Therefore, the NBA and USA Basketball have established detailed guidelines to help young players develop at a natural pace that is suitable to their age and physiological abilities.

The NBA and USA Basketball have worked closely with an expert working group on Playing Standards to develop age- and stage-appropriate rules and standards for youth basketball.  Aligning with the Player Segmentation Model, these guidelines will help young players appropriately learn the fundamentals of the game, achieve and maintain early success, and provide enhanced long-term development.

The rules and standards address four key areas:

  1. Equipment & Court Specifications (e.g., proper height of the basket, size of the ball, and court dimensions and lines).
  2. Game Structure (e.g., length of the game, scoring and timeouts).
  3. Game Tactics (e.g., equal playing time, player-to-player vs. zone defense, pressing vs. no pressing).
  4. Game Play Rules (e.g., use of a shot clock, substitutions, clock stoppage).

Rules and Standards Charts
See below for detailed rules and standards information.  Please keep in mind:

  • The playing rules and standards below are to serve as guidelines and recommendations for those administering basketball competitions.
  • The NBA and USA Basketball have adopted FIBA (International Basketball Federation) rules for the Grades 9-12 age- segment and created progressive sets of rules and standards for younger age segments (ages 14 and under). Where a specific rule or standard is not explicitly indicated, the recommendation is to follow official FIBA rules.
  • The NBA and USA Basketball will utilize these playing rules and standards in all events and competitions they may host.

*We understand that organizations and facilities may not always be able to accommodate all recommendations and that modifications will need to be made in certain instances due to practical limitations (e.g., inability to raise or lower the height of a basket, re-draw court lines, or not having a shot clock).
