Question: What is the name of the NBA's process of jumping directly from high school to the professional level which was adopted in 2006?

<P0-S0> Brandon Byron Jennings (born September 23, 1989) is an American professional basketball player for the Shanxi Brave Dragons of the Chinese Basketball Association (CBA). <P0-S1>  After a year in Italy, Jennings declared for the 2009 NBA draft and was selected 10th overall by the Milwaukee Bucks. <P0-S2>  He played his first four seasons in Milwaukee before being traded to the Detroit Pistons in 2013. <P0-S3>  Jennings spent his next three seasons in Detroit before he was traded to the Orlando Magic in 2016. <P0-S4>  He went on to split the 2016–17 season with the New York Knicks and Washington Wizards. <P0-S5>  After graduating from Oak Hill Academy, he decided to play professional basketball with Italian club Lottomatica Roma, leading to controversy and debate on the NBA's "prep-to-pro" policy that was adopted in 2006. <SEP> <P1-S0> The NBA Slam Dunk Contest (officially known as the Verizon Slam Dunk for sponsorship reasons) is an annual National Basketball Association (NBA) competition held during the NBA All-Star Weekend. <P1-S1>  The contest was inaugurated by the American Basketball Association (ABA) at its All-Star Game in 1976 in Denver, the same year the slam dunk was legalized in the NCAA. <P1-S2>  As a result of the ABA–NBA merger later that year there would not be another slam dunk contest at the professional level until 1984. <P1-S3>  The contest has adopted several formats over the years, including, until 2014, the use of fan voting, via text-messaging, to determine the winner of the final round. <SEP> <P2-S0> 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. <P2-S1>  The process of jumping directly from high school to the professional level is also known as going prep-to-pro. <P2-S2>  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. <P2-S3>  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 (especially overseas) like Brandon Jennings or Emmanuel Mudiay in Italy and China respectively, simply take the year off, such as the case with Satnam Singh Bhamara, or even hold themselves back a year in high school before declaring for the draft, such as the case with Thon Maker. <SEP> <P3-S0> College baseball is baseball that is played on the intercollegiate level at institutions of higher education. <P3-S1>  In comparison to football and basketball, college competition in the United States plays a smaller role in developing professional players, as baseball's professional minor leagues are more extensive. <P3-S2>  Moving directly from high school to the professional level is more common in baseball than in football or basketball. <P3-S3>  However, if players enroll at a four-year college, they must complete three years to regain eligibility, unless they reach age 21 before starting their third year of attendance. <P3-S4>  Players who enroll at junior colleges (i.e., two-year institutions) regain eligibility after one year at that level. <P3-S5>  In the most recently completed 2017 season, there were 298 NCAA Division I teams in the United States (including schools transitioning from Division II to Division I).
