#10: Thomas Jefferson High School (New York City, N.Y.) — 10 players

Jefferson High is located in Brooklyn and once was one of the preeminent schools for successful individuals in all sectors of life, not only for athletes.
Few schools can say they produced a heavyweight champion (Riddikk Bowe), a Golden Globe and Emmy winner (Jimmy Smits) and the chairman of Goldman Sachs (Lloyd Blankfein).
The NBA players from the school mostly played in the early days of the league, including Max Zaslofsky, the NBA's scoring champion in its second season in 1947-48.
Jefferson High lasted for 85 years until it was shut down in 2007 due to low graduation rates.

#9(t): Proviso East High School (Maywood, Ill.) — 12 players

Only New York City has produced more NBA players than Chicago, and Proviso East is located in a suburb of the Windy City. The sheer number of students has lent itself to many opportunities for notable athletes to emerge as the school had an enrollment of 4,000 in the 1970s.
That time period is when Doc Rivers was a Proviso East Pirate, and he coached another alum of the school, Michael Finley. A two-time NBA All-Star, Finley brought Proviso East a state championship in 1991 and played for Rivers on the Boston Celtics nearly two decades later.

#9(t): Overbrook High School (Philadelphia, Pa.) — 12 players

The legend of Wilt Chamberlain began at Overbrook High, where he won two city championships and set Pennsylvania’s all-time high school scoring record.
It was also in high school where the Stilt first attracted the attention of the NBA as Red Auerbach tried to persuade Chamberlain to go to a college near Boston so the Celtics could draft him as a territorial pick.
None of the 11 other players to attend Overbrook had anything close to the hype that Chamberlain generated.
While they were all serviceable players, they combined to make just one NBA All-Star Game. That came courtesy of Walt Hazzard, who was an All-Star in 1968, the same year another future Overbook High alum was born, actor Will Smith.

#9(t): Henderson International School (Henderson, Nev.) — 12 players

Findlay Prep is the name of the basketball program that operates out of Henderson International School, but many contend it’s more of an AAU program than a school.
The 12 basketball players on the team comprise the entire enrollment of Henderson, and they barnstorm the country to play a national schedule, leaving academics as almost an afterthought.
The NCAA caught wind of this "school" and labeled Findlay Prep as "non-scholastic," which means college coaches can’t conduct in-person recruiting.
But the school still has no problem attracting top talent. Currently, nine players from Findlay are in the NBA, including Tristan Thompson and Avery Bradley.
And many other Findlay alums play in the G-League or abroad, such as former No. 1 overall pick Anthony Bennett.

#6(t): Laurinburg Institute (Laurinburg, N.C.) — 13 players
Laurinburg Institute has a history of basketball excellence.blackathlete.net
Just like Hargrave, Laurinburg Institute is another school outside of Charlotte that accepts post-graduates. Basketball is the only sport offered at the school, so all of the athletic resources are devoted to their hoops program which won a national title in 2005 after defeating Hargrave.
None of the 13 alums from Laurinburg are currently in the NBA, but two of the 13 alums are in the Pro Basketball Hall of Fame. Ten-time NBA champion Sam Jones and five-time All-Star Charlie Scott have been enshrined in Springfield, Mass.
#5(t): Hargrave Military Academy (Chatham, Va.) — 14 players

Hargrave is a private boarding school that’s about a two-hour drive from Charlotte. The school is known for its military program (which is similar to the Army’s) and for producing world-class athletes in multiple sports.
Hargrave is one of the three schools on this list which also is on the top NFL players produced list, and unlike its football program, its basketball program still allows for post-graduates.
All of the school’s NBA players come from the post-graduate program, which has featured the likes of David West and Josh Howard.

#5(t): Brewster Academy (Wolfeboro, N.H.) — 14 players

Of the 28 players who have made their way from a New Hampshire high school to the NBA, half of them passed through the expensive halls of Brewster Academy.
The boarding school’s tuition is over $60,000, making it the most expensive school in the state and one of the most expensive in the country.
The world-class facilities at Brewster are one of the biggest drawing points for prospective students and include a 50,000-square-foot athletics center, indoor and outdoor turf fields, a boathouse, a rowing tank and a climbing wall.
Seven active NBA players once hooped at Brewster, including Utah Jazz guard Donovan Mitchell.

The third and final school on this list that also is on the NFL version of this list, DeMatha has twice been named the No. 2 high school athletic program in the country.It is just outside of Washington, D.C., but the school attracts students from all over the DMV area.
At least one alum of DeMatha has been in the NBA for 48 of the last 50 seasons. This includes a Hall of Famer (Adrian Dantley), a current All-Star (Victor Oladipo) and a recent No. 1 overall draft pick (Markelle Fultz).

#3(t): DeWitt Clinton High School (New York City, N.Y.) — 18 players

Located in the Bronx, DeWitt Clinton was once the largest high school in the world with over 12,000 students in the 1930s. Today, its enrollment is about 1,400, and that large drop-off also has impacted its NBA alums.
Nearly all of the DeWitt Clinton graduates to make it to the NBA played before the ABA-NBA merger in 1976, and none have played in the last 20 years.
These days, many of the prominent New York prep players opt to go to school in the suburbs or head to a boarding academy elsewhere as New York City overall has seen a drop-off in NBA players produced.
Hall of Famers Dolph Schayes and Tiny Archibald highlight the best players who once were DeWitt Clinton Governors.

#1: Oak Hill Academy (Mouth of Wilson, Va.) — 29 players

What do the University of Alabama, Boston College and the University of Oklahoma have in common? They all are in Power 5 Conferences, yet each of them has produced fewer NBA players than a tiny boarding school on the Virginia-North Carolina border.
Oak Hill Academy has an enrollment of just 132 students, and high school basketball players from across the country know that there is no better place to prepare you for the next level. Carmelo Anthony moved from Baltimore to attend Oak Hill. Rajon Rondo came from Louisville. Brandon Jennings moved from Compton, and Steve Blake relocated from Miami, just to name a few.
The school even recruits international prospects, including DeSagana Diop, who came from Senegal.
Oak Hill has been named the national high school champion nine times under coach Steve Smith, who also has produced 28 McDonald’s All-Americans.
Seven Oak Hill graduates currently are in the NBA with more on the way. The school had three of the top four ranked players in the state of Virginia for the class of 2018.
