The pledge emblem is very prevalent in the symbolism of the fraternity; not only is the emblem on the pledge pin, but the emblem also graces the flag, the membership badge and the basic design is also the basis of the fraternity's seal. Prior to the adoption of Vision 2025, Delta Sigma Phi was providing leadership training and development to fewer than 500 students annually. Since the creation of a number of new programs, more than 1,600 members receive annual leadership development & training from the national organization annually. With the launch of Delta Sig's online learning management system in the fall of 2013, that number will hit 100 percent of the undergraduate membership by 2015. Delta Sigma Phi's flagship leadership program is the Leadership Institute, celebrating its 20th Anniversary in the summer of 2013. The Leadership Institute is based on Kouzes & Posner's Five Practices of Exemplary Leadership and engages members in a curriculum including large & small group discussions, team-building activities, high-ropes courses, and personal assessment and reflection. Members apply to attend LI, however there is no limit to the number of members that may be admitted from each chapter. It is a 5-day program in Indianapolis each summer (though it was moved to Phoenix in 2013 to coordinate with the 2013 convention for the 20th Anniversary) and is free to undergraduate Delta Sigma Phi members. More than 1,000 men have graduated from the Leadership Institute to date. Regional Leadership Academies (RLAs) were developed following the adoption of Vision 2025 to target a wider audience of the membership and provide development and training on the business and day-to-day operations of chapters. In 2013, Delta Sigma Phi held four RLAs, allowing each chapter to send up to 10 members at no additional cost to its paid in membership dues. The content of the RLAs have changed each year as members needs and requests evolve, though the one-day program has maintained tracks regarding Risk Management & Recruitment since inception. For the 2012–2013 academic year, RLAs were in Atlanta, Georgia; Indianapolis, Indiana; Philadelphia, Pennsylvania; and Santa Clara, California. Delta Sigma Phi also piloted two statewide regional events in the 2012–13 school year for chapters in Wisconsin, Minnesota and Texas. These chapters were exempted from the requirement to participate in RLA and were invited to bring more than 10 men from each of their memberships. For the 2013–14 academic year, the fraternity expanded the RLA program to 16 state or local-region sessions throughout the fall and spring. With this new concept, roughly 1,600 men were anticipated to participate in RLAs.
