By April 9, 1990, the University of Iowa Panhellenic Council officially recognized the organization as a sorority, which Sigma Lambda Gamma celebrates as its founding date.

This network was created to embody a shared commitment to unity and mutual support across these diverse Greek organizations.

[9] While chapters have always organized local programming on their respective campuses, Sigma Lambda Gamma later created the Education Foundation.

[14][15] In 2012, the Panther Dash For Education was developed to generate funds that will support scholastic achievement and leadership training.

Although Sigma Lambda Gamma's website once stated support for the Susan G. Komen for the Cure and Y-ME National Breast Cancer Organization, they currently do not affiliate with either one.

[27][28] Additionally, they launched a partnership with the American Red Cross after attending the 2017 Diversity in Aquatics Symposium, focusing on educating about the importance of water safety.

[29][28] In 2020, they publicly voiced their support for the Black Lives Matter movement after the murder of Ahmaud Arbery, an unarmed 25-year-old African-American man, who was pursued and fatally shot while jogging near Brunswick in Glynn County, Georgia.

[13] To encourage members to mobilize their bodies as well as give back to the community, Sigma Lambda Gamma created the Panther Dash for Education in 2012.

Members can participate in any 5K race of their choice and purchase Sigma Lambda Gamma packages, such as a bib, T-shirt, or water bottle with the sorority's letters and logo, to raise funds.

Based on the results of this self-assessment, members will have the chance during the academic year to learn more about the nineteen different skills of emotional intelligence.

[13] Annual scholarships are given to members who have been initiated into the organization and are in good standing, as defined by Sigma Lambda Gamma policy, who are enrolled as degree-seeking students during the academic year.

[5] The regions are as follows: A criterion for membership into Sigma Lambda Gamma is that a woman or non-binary individual must have exceptional morals and ethics with a demonstrated commitment to academic excellence, and is pursuing or has completed courses leading to a degree in an accredited college or university.

According to Sigma Lambda Gamma's national constitution, they believe that a multicultural experience during the college years enhances each member's ability to function in a pluralistic society.
