Annual vs. Biennial Legislative Sessions


Legislatures continually look for ways to improve their effectiveness. One reform that often is debated is annual versus biennial legislative sessions.

In the early 1960s, only 19 state legislatures met annually in regular session. The remaining 31 held biennial regular sessions. Most held their biennial session in the odd-numbered year; only Kentucky, Mississippi and Virginia met during the even-numbered year. By the mid-1970s, the number of states meeting annually grew tremendously—up from 19 to 41. Today, 46 state legislatures meet annually. The remaining four states—Montana, Nevada, North Dakota and Texas—hold session every other year, and all of these biennial legislatures hold their regular sessions in the odd-numbered year.

Oregon, Arkansas, Kentucky, New Hampshire and Washington were the last states to change from biennial to annual regular sessions; these states held their first annual sessions in 2011, 2009, 2001, 1985 and 1981, respectively.

There are several basic arguments used by the respective proponents. Listed below are the ones set out by political scientists, William Keefe and Morris Ogul.


For Annual Sessions

For Biennial Sessions

1. The biennial format is unsuitable for dealing with the complex and continuing problems which confront today’s legislatures. The responsibilities of a legislature have become so burdensome that they can no longer be discharged on an alternate-year basis.

1. There are enough laws. Biennial sessions constitute a safeguard against precipitate and unseemly legislative action.

2. More frequent meetings may serve to raise the status of the legislature, thereby helping to check the flow of power to the executive branch.

2. Yearly meetings of the legislature will contribute to legislative harassment of the administration and its agencies.

3. Continuing legislative oversight of the administration becomes more feasible with annual sessions, and that administrative accountability for the execution of legislative policies is more easily enforced.

3. The interval between sessions may be put to good advantage by individual legislators and interim study commissions, since there is never sufficient time during a session to study proposed legislation.

4. States may respond more rapidly to new federal laws which require state participation.

4. The biennial system affords legislators more time to renew relations with constituents, to mend political fences and to campaign for reelection.

5. The legislature cannot operate effectively in fits and starts. Annual sessions may help make the policy-making process more timely and orderly

5. Annual sessions inevitably lead to a spiraling of legislative costs, for the legislators and other assembly personnel are brought together twice as often.

6. Annual sessions would serve to diminish the need for special sessions.
