The South Carolina Chapter of US Lacrosse Board of Directors established the SCLL in the fall of 2001. The purpose was to provide an opportunity for the boys and girls high school lacrosse teams to compete in a league where a year end champion would be recognized. The first SCLL Tournament was held in Myrtle Beach in May of 2002. Six teams competed and the Hilton Head Girls and Boys teams won the first South Carolina High School Lacrosse Championships.

The year 2003 saw a very successful SCLL Tournament held in Hilton Head and once again the Hilton Head High School Boys and Girls walked away with the title after a very competitive struggle. There were eight teams competing that year.

The SCLL tournament in 2004 was held at Presbyterian College, in Clinton, S.C. Growth of lacrosse in South Carolina was put on display as there were 16 teams competing. One of the newest boys high school teams, Greenville High, made it to the championship game eventually losing out to Hilton Head in a three-peat performance.

The 2005 SCLL tournament was held at Bluffton High School on April 30th and May 1st. 2005. Due to the new and ever increasing number of teams and the establishment of a Western and Eastern Division, a playoff system was used to determine the 8 girls and the 8 boys high school teams to qualify for the championship weekend. Hilton Head boys, once again, took home state championship honors but had to fight off a vastly improved and talented Greenville High School team for a 12 to 8 victory. Mauldin girls knocked off the defending champion Hilton Head team in the first round and Ridgeview met Bluffton in the championship game. Ridgeview copped the 2005 girl's state lacrosse championship by a convincing 9 to 3 score.

The SCLL held it's first All Star games at Heathwood Hall Episcopal School on May 7th. 2005. The competition was remarkable as the girls All Star team from the West prevailed over the East by 2 goals. The middle school boys and high school boy's games both went into overtime with the South's middle school team winning. In the boys high school game the West prevailed over the East.

The chapter board, in May 2006, established an SCLL Executive Committee headed by Rich Thomas, as commissioner and boys and girls representatives for both the Eastern and Western Divisions..

The 2006 season had 18 boy's high school teams and 15 girl's high school teams competing for the state championship.

The 2006 SCLL championship tournament had divisional playoffs on April 26th and 29th. Heathwood Hall Episcopal School, in Columbia, hosted the semi-finals on Friday May 5th and the boy's and girl's championship games on Saturday May 6th. The level of lacrosse was quite evident as two teams from the Western Division copped both boys and girls championships for the first time. Greenville boys upset Heathwood Hall 16 to 13 and the JL Mann girl's team outlasted Eastside in a thrilling game 11 to 10. The SCLL All Star game was held at Presbyterian College, in Clinton, on Saturday May 13th with the Western Division boys and girls teams being victorious.

More boys and girls teams came on board in the Charleston area (Mt. Pleasant) in 2007 with the formation of the Charleston Warriors. Also Woodmont High School, in the Greenville area, had both boys and girls teams join the SCLL for the 2007 season. The SCLL, in 2007, had 17 girl's high school teams and 20 boy's high school teams.

The 2007 SCLL tournament was held in Greenville on may 4th and 5th.The the Greenville High boys beat Wando in overtime and the J.L.Mann girls defeated Eastside to repeat as state champions.

Heathwood Hall was host for the 2007 SCLL All Star Games on Saturday May 12th. The West boys and girls high school teams prevailed, once again while the boys middle school game ended in a tie.

The Chapter Board intends to continue the SCLL and the championship format until such time as the South Carolina High School League sanctions lacrosse as an official state high school sport.
