2008–2011: Early seasons Eric Altamirano and
Alex Compton, the heads of the NBTC, wanted to reach out to more rural areas, so they thought of developing a school-based league. In 2008, the NBTC Developmental League, a 16-and-under tournament, was formed, with Altamirano serving as its tournament director. 29 teams participated in the inaugural tournament, with 24 from Luzon, Visayas, and Mindanao, and five from the NCR. The tournament culminated in 2009 with Smart Sports Manila winning the national championship with a team led by
Mike Tolomia,
Russel Escoto,
Baser Amer and
Kiefer Ravena. Prior to the start of the new season, Compton left his role as an assistant coach of the
Rain or Shine Elasto Painters to become the NBTC D-League's director. However, he was reassigned as the training director while Atty. Manny Nitorreda became the tournament director. On December 6, 2009, the new NBTC D-League season began. From 29 teams that participated in the inaugural tournament, that number increased to 108. Two championships were awarded that year, one for NCR teams, and one for teams from the province. B-Meg Expert Cebu, with a team from the
University of the Visayas (UV), won the provincial championship, while Smart-Manila claimed the NCR title. For the 2010–11 season, a selection from Cebu would win the national championship over St. John's Institute Bacolod, which was led by
Kib Montalbo.
2011–2015: Introduction of NBTC All-Star Game In the 2011–2012 season, the NBTC added an All-Star Game to its league (now known as the Seaoil Elite League). This was patterned after the
McDonald's All-American Game in the US. 75 players tried out to take part in the event, with a selection committee composed of NBTC coaches and media selecting 30 players. Former
Smart Gilas Pilipinas head coach
Rajko Toroman held a basketball seminar for those selected to play in the All-Star Game. The first ever All-Star Game featured
Jeron Teng and
Thomas Torres with unknown Ace Basas claiming the first-ever All-Star Game MVP. That season, 17 teams made it to the Elite League Finals. It was also the third time a team from Cebu won the title. For the 2012–13 season, 248 teams participated. The NBTC also partnered with the Metro Manila Basketball League (MMBL) to bring in more teams from the NCR. MMBL semifinalists Hope Christian High School,
San Beda College, Faith Academy, and
National University represented the NCR in the finals, with 12 other teams coming from other regions. Hope Christian took down reigning champions Sacred Heart School in the semifinals. San Beda, led by
Arvin Tolentino, won the tournament over Hope Christian. For the 2013–14 NBTC Finals, 24 teams were grouped into two divisions. San Beda didn't qualify for the Finals as they didn't make the semis of the MMBL, thus they weren't able to defend their title. The
Chiang Kai Shek Dragons, who had also won the MMBL, were crowned as the new champions after defeating NU. The 2014–15 season saw Chiang Kai Shek repeat as MMBL champions, while Sacred Heart School won the Cebu leg for the 5th time. They comprised two of the 18 teams which qualified for that year's National High School Championships. In the end, Sacred Heart School defeated San Beda to claim its 3rd NBTC title, which was also the first title they claimed over an opponent from the NCR.
2015–2019: NBTC goes international The 2015–16 SM NBTC season saw Durham Crossover from Canada and
Trail International School from Thailand become the first international teams to join the league, along with 536 other schools. They lost to Chiang Kai Shek and Sacred Heart School respectively early in the tournament. However, they both lost in the semis to NU and Sacred Heart School respectively. In the Finals, behind John Lloyd Clemente and
Justine Baltazar, the Bullpups won that season's championship. That year,
Ricci Rivero became the first winner of the NBTC Slam Dunk Contest. For the 2016–17 season, 700 schools participated. A regional highlight included the
USLS Junior Stingers heading to the national finals for the first time. The
FEU Baby Tamaraws (who were the UAAP juniors champions) also played in their first NBTC national tournament. Other teams in that year's finals included SHS – Ateneo, San Beda, the Malayan Red Robins, FilAm Sports USA (led by
Kamaka Hepa) and more. San Beda, led by
Evan Nelle, went perfect in the finals, overcoming FilAm Sports, FEU, and SHS – Ateneo to win the title. The 2017–18 season introduced a power ranking of the top 24 high school players in the country. Sotto would end up becoming the #1 ranked player in the country for that season. In that year's MMBL season, Chiang Kai Shek won the championship over San Beda. In the Cebu leg, UV beat SHS – Ateneo to become the new champions of the region. Meanwhile,
Bacolod Tay Tung High School won the Negros Occidental leg. The 2018 NBTC league finals featured 32 teams bracketed
March Madness-style. Other notable teams included in this season's tournament included #1 Ateneo, the defending champions San Beda, the
Carl Tamayo-led NU Bullpups, and a FilAm Sports team led by
Jalen Green,
Kihei Clark and Elijah Jackson. In the Elite 8, Green scored 51 points, the most ever scored in the finals tournament, but it wasn't enough as they lost to NU. There, the Bullpups beat LSGH to win it all for the second time in three seasons. The season closed with the All-Star festivities, where Team Hustle won the All-Star Game and Green won the slam dunk contest. For the
2019 NBTC National Finals, six international teams joined and 105 cities from all over the nation were represented in the tournament. Prominent teams included defending champions NU, NCAA champions Malayan, and FilAm Sports (with Green, Jeron Artest, Eli Ramos, Kainoa Ballungay, and
Boogie Ellis). Highlights of the Sweet 16 rounds included Crossover Canada breaking through to the Elite 8 for the first time, and Green and Ballungay leading FilAm Sports past Sotto's Ateneo. Crossover Canada was then eliminated by FEU, while FilAm Sports were defeated by San Beda. At the end of the tournament, NU became the first back-to-back champions in tournament history. In the All-Star festivities, Team Hustle won once again and Green and David Carlos both ended up winning the slam dunk contest.
2019–2022: Cancelled seasons The 2019–20 season began on October 15, 2019. Regional champions for that season included
UC High School and Cauayan City High School for the Cordilleras and Region II, SHS – Ateneo for Cebu, the HCCD Red Eagles for Davao, and Tay Tung High School for Western Visayas. However, the National Finals were moved to a later date due to the
COVID-19 pandemic. Eventually, they were cancelled.
2022–present: Return of NBTC The NBTC made its return in 2022 with the Global Games, a series of international NBTC Finals qualifiers for Filipinos in different parts of the world. The games lasted from July to November with 7 international teams heading to the nationals. They league opened up the tournament to local club teams, with local qualifiers beginning in August 2022. In the NBTC rankings for that season,
Jared Bahay, from SHS – Ateneo, became the first player from the province to be ranked as the best high school player in the country. 24 teams participated in the
National Finals' return. Jumamoy was able to lead NU back to the finals with a double overtime win over Ateneo. In the Finals, NU won its third straight championship over
Fil-Am Nation Select. Jumamoy swept the awards winning both MOP awards, Best Defensive Player, and a spot on the Mythical Five. For the first time since international teams started participating in the NBTC National Finals in 2016, international teams won both Division 1 & Division 2 titles, with
Fil-Am Nation Select–USA winning Division 1 and Top Flight Sports-Canada West winning Division 2. == NBTC League National Champions ==
