NVSL-Dive hosts the annual Cracker Jack Invitational. This meet is the world's largest one-day diving competition. At the 2009 meet, which was hosted by Truro in Annandale, Virginia, 354 divers (218 girls and 136 boys) competed. Established in 1987 to provide a skill-appropriate championship for beginning divers. The first Cracker Jack Invitational was held at Freedom Park and attracted approximately 600 divers. For many years, this meet was hosted by Overlee pool in Arlington, Virginia, and moved to Cardinal Hill in Vienna for 2007 and 2008. In 2012, the meet was hosted by Mansion House.
Since its beginning in 1987, more than 9,000 divers have competed at Crackerjack. NVSL-Dive sponsors an annual 3-meter meet. Col. Wallace R. Martin arranged for the meet to be held at his home pool, Tuckahoe, in 1968 and then again every year thereafter for the rest of his life. Martin died in 1977, and in 1978 the NVSL 3-Meter Meet was renamed the Wally Martin 3-Meter Championship in his memory.
