National Conference of State Legislatures

The National Conference of State Legislatures (NCSL), established in 1975, is a "nonpartisan public officials’ association composed of sitting state legislators" from the states, territories and commonwealths of the United States.
Background.
According to their website, the mission of the Conference is: to advance the effectiveness, independence and integrity of legislatures and to foster interstate cooperation . . . especially in support of state sovereignty and state flexibility and protection from unfunded federal mandates and unwarranted federal preemption. The conference promotes cooperation between state legislatures in the U.S. and those in other countries. . . . [and] is committed to improving the operations and management of state legislatures, and the effectiveness of legislators and legislative staff. NCSL also encourages the practice of high standards of conduct by legislators and legislative staff.
NCSL maintains an office in Denver, Colorado and Washington, D.C.
Eight Standing Committees, composed of legislators and legislative staff appointed by the leadership of the legislatures, serve as the central organizing mechanism for NCSL members. Each Committee provides a means by which state legislators can share experience, information, and advice on a variety of state issues ranging from policy to management. 
Committees meet together twice each year at the NCSL Capitol Forum and NCSL's Legislative Summit to adopt state-federal legislative policies that will ultimately guide NCSL's lobbying efforts in Washington, D.C. These committee meetings also serve as an opportunity for states to network and establish flows of information as well as experience-based suggestions from other states. In addition to the NCSL Capitol Forum and the Legislative Summit, NCSL builds the state legislative community by hosting various web seminars, leadership meetings, and access to relevant websites and online documents throughout the year. 
Issues spanning multiple committee jurisdictions are managed by NCSL's Task Forces. Unlike the permanent Standing Committees, Task Forces are created for a specific period time and aim to develop positions on highly complex and controversial issues such as immigration reform and welfare. Task Forces are composed of 20 to 30 legislators and legislative staff who are appointed by the NCSL president or staff chair. 
Day-to-day operations of the organization managed by its Executive Director, Tim Storey. The organization is led by a legislator who serves as its president and by a legislative staffer who serves as staff chair. Twenty years after its founding, NCSL was led in 1994 by its first female president, former Congresswoman Karen McCarthy. Its first African-American president, Rep. Dan Blue, served in 1998–99. The 2019–20 president of NCSL is Representative Robin Vos of Wisconsin, and the staff chair is Martha Wigton of Georgia. Each year, NCSL's presidency alternates between legislators of the Republican and Democratic parties.
The NCSL is considered part of the 'Big Seven', a group of organizations that represent local and state government in the United States.
Committees.
NCSL has 8 standing committees whose membership consists of state legislators and staff:
These committees establish policy positions and coordinate lobbying efforts in Washington DC.
Task forces.
NCSL uses task forces to complement the work of the 8 standing committees. Composed of legislators and legislative staff, task forces are temporary and deal with issues that cut across the jurisdictions of multiple standing committees. Currently, there are 8 task forces:
Policy positions.
In the most general terms, NCSL works to enhance the role of states in the federal system. NCSL opposes unfunded federal mandates and federal preemption of state authority, providing state legislatures with the flexibility to implement policy solutions. 
NCSL supports enactment of the Main Street Fairness Act, which would simplify existing sales tax collection laws. The Act would grant states the authority to require all sellers, including online merchants, to collect sales and use taxes, generating billions of dollars of tax revenue for state governments. 
Professional staff associations.
The organization runs nine professional staff associations.
American Society of Legislative Clerks and Secretaries.
The American Society of Legislative Clerks and Secretaries (ASLCS) was founded in 1943 to improve legislative administration, and to establish better communication between clerk and secretaries throughout the United States and its territories. In 1974, ASLCS joined with several state legislative groups to form the National Conference of State Legislatures (NCSL). The society includes an active membership of more than four hundred principal clerks, secretaries, and legislative support staff.
Publications and standards.
ASLCS publishes several reference and resource books, including the Legislative Administrator, the Professional Journal, the Roster and Reference Guide, the International Directory, Mason's Manual 
The Legislative Administrator is the official newsletter of the American Society of Legislative Clerks and Secretaries.
Professional Journal
"The Journal" provides a forum to share experiences, expertise and opinions on a variety of subjects influencing our daily working environment.
International Directory
The International Directory is a booklet that provides a resource in English, Spanish and French of the objectives and goals of the American Society of Legislative Clerks and Secretaries (ASLCS), Association of Chief Clerks of Mexico's State Legislatures and the Federal Dict of Mexico (ANOMAC), Association of Central American Legislative Clerks (ATELCA), the Canadian Clerks-at-the Table, South African Legislative Secretaries Association (SALSA), and the Australian Clerks. The booklet also contains the names, phone numbers, fax numbers and e-mail addresses of the Executive Committee members of the respective organizations.
Inside the Legislative Process
Inside the Legislative Process is a research tool, providing information on state legislative processes and procedures. The ASLCS committee on Inside the Legislative Process is responsible for reviewing and producing this publication. The committee works closely with NCSL staff to develop survey questions and record the responses in a format that is easily usable by all legislative units and reflects current legislative processes.
International relations.
Additionally, the Joint Canadian-American Clerks' Conference is held biennially in odd-numbered years. It is hosted alternately between Canada and the United States. Unlike other Society meetings, participation in this conference is limited to principal clerks and secretaries or to the principal assistant if the clerk or secretary is unable to attend. The meeting typically occurs in August or September. The location is determined by joint recommendation of the ASLCS Canadian/American Relations Committee and the Canadian Association of Clerks-at-the-Table.
Events.
NCSL organizes two annual events for the general membership:
The Legislative Summit is the largest of these events, partly because it occurs in the summer when state legislatures are in recess. Its location varies year to year. The NCSL Capitol Forum alternates between Washington D.C. and a location that varies year to year.
