Context: The NBA high school draftees are players who have been drafted to the National Basketball Association (NBA) straight out of high school without playing basketball at the collegiate level. The process of jumping directly from high school to the professional level is also known as going prep-to-pro. Since 2006, the practice of drafting high school players has been prohibited by the new collective bargaining agreement, which requires that players who entered the draft be 19 years of age and at least one year removed from high school. Contrary to popular belief, the player does not have to play at least a year in college basketball, as the player can choose to instead play in another professional league (like the NBA G League or especially somewhere overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Mitchell Robinson, or even hold themselves back a year in high school before declaring for the draft, like with Satnam Singh Bhamara or Thon Maker.

Like many professional sports leagues, the NBA has a salary cap to control costs, defined by the league's collective bargaining agreement (CBA). This limit is subject to a complex system of rules and exceptions and as such is considered a soft cap and is calculated as a percentage of the league's revenue from the previous season. Under the CBA ratified in December 2011, the cap will continue to vary in future seasons based on league revenues. For the 2015--16 season, the salary cap was $70 million and the luxury tax limit was $84.74 million. For the 2016--17 season, the salary cap was set at $94.14 million and the luxury tax limit was $113.29 million. For the 2017--18 season, the cap is set at $99 million for the salary cap and $119 million for the luxury tax.

The birth certificate is typically issued by local governments, usually the city or county where a child is born. It is an important record, often called a ``feeder document,'' because it establishes U.S. citizenship through birthright citizenship, which is then used to obtain, or is the basis for, all other identity documents. By itself, the birth certificate is usually only considered proof of citizenship but not proof of identity, since it is issued without a photograph at birth, containing no identifying features. A birth certificate is normally produced along with proof of identity, such as a driver's license or the testimony of a third party (such as a parent), to establish identity or entitlement to a service.
