About the chamber

Members of the Illinois State Senate serve four-year terms and are not subject to term limits. Under the Illinois Constitution of 1970, Senators are divided into three groups. Each group has a two-year term at a different part of the decade between censuses, and the rest of the decade is taken up by two four-year terms. Depending on the election year, roughly one-third, two-thirds, or all of the senate seats may have terms ending.

All three groups hold elections in the first election year following the decennial census and subsequent redistricting (i.e. 1992, 2002, 2012, etc.). Starting with that election, the terms for the three groups are structured as follows:

• Group 1: four-year term, four-year term, two-year term
• Group 2: four-year term, two-year term, four-year term
• Group 3: two-year term, four-year term, four-year term

Illinois legislators assume office the second Wednesday in January.

Qualifications

Article IV of the Illinois Constitution states: "To be eligible to serve as a member of the General Assembly, a person must be a United States citizen, at least 21 years old, and for the two years preceding his election or appointment a resident of the district which he is to represent."

Salaries

Vacancies

If there is a vacancy in the senate, the Illinois Constitution mandates that the seat must be filled by appointment when allowed by law. The appointment must be made within 30 days after the vacancy. If a vacancy by a member of the senate has more than twenty-eight months remaining in the term, the appointment is interim until the next general election and in this case, a special election must be held to fill the balance of the unserved term. All other senate vacancies should be made by appointment with the person appointed being a member of the same political party that last held the seat.

The vacancy must be filled by the respective party organizations covering the legislative district. This must be voted on by the respective committeemen and committeewomen representing the legislative district.
