Debate is a process that involves formal discourse, discussion, and oral addresses on a particular topic or collection of topics, often with a moderator and an audience. In a debate, arguments are put forward for opposing viewpoints. Historically, debates have occurred in public meetings, academic institutions, debate halls, coffeehouses, competitions, and legislative assemblies. Debates have also been conducted for educational and recreational purposes, usually associated with educational establishments and debating societies. These debates emphasize logical consistency, factual accuracy, and emotional appeal to an audience. Modern competitive debate also includes rules for participants to discuss and decide upon the framework of the debate.
Lincoln–Douglas debate is a type of one-on-one competitive debate practiced mainly in the United States at the high school level. It is sometimes also called values debate because the format traditionally places a heavy emphasis on logic, ethical values, and philosophy. The Lincoln–Douglas debate format is named for the 1858 Lincoln–Douglas debates between Abraham Lincoln and Stephen A. Douglas, because their debates focused on slavery and the morals, values, and logic behind it. LD debates are used by the National Speech and Debate Association (NSDA) competitions, and also widely used in related debate leagues such as the National Christian Forensics and Communication Association, the National Catholic Forensic League, the National Educational Debate Association, the Texas University Interscholastic League, Texas Forensic Association, Stoa USA and their affiliated regional organizations.
Policy debate is an American form of debate competition in which teams of two usually advocate for and against a resolution that typically calls for policy change by the United States federal government. It is also referred to as cross-examination debate because of the 3-minute questioning period following each constructive speech. Evidence presentation is a crucial part of policy debate. The main argument being debated during a round is to change or not change the status quo. When a team explains why their solvency is greater than the opposition's, they compare advantages. One team’s job is to argue that the resolution— the statement that we should make some specific change to a national or international problem —is a good idea. Affirmative teams generally present a plan as a proposal for implementation of the resolution. On the other hand, the Negative teams present arguments against the implementation of the resolution. In a single round of debate competition, each person gives two speeches. The first speech each person gives is called a “constructive” speech, because it is the speech when the first person of the team speaks positively, presenting the team's main idea without rebuttals that have not occurred, presents the basic arguments they will make throughout the debate. The second speech is called a “rebuttal”, because this is the speech where each person tries to rebut the arguments made by the other team, while using their own arguments to try to persuade the judge to vote for their team. The Affirmative has to persuade the judge to vote for the resolution, while the Negative has to persuade the judge the Negative's position is a better idea.
The American Parliamentary Debate Association (APDA) is the oldest intercollegiate parliamentary debating association in the United States. APDA sponsors over 50 tournaments a year, all in a parliamentary format, as well as a national championship in late April. It also administers the North American Debating Championship with the Canadian University Society for Intercollegiate Debate (CUSID) every year in January. Although it is mainly funded by its member universities, APDA is an entirely student-run organization.
The College Preparatory School is a four-year private non-residential high school in Oakland, California. The school's motto is Mens Conscia Recti, a Latin phrase adapted from Virgil's Aeneid that means "a mind aware of what is right".
Public forum debate is a form of competitive debate where debaters use their evidence and impacts to outweigh the benefits and harms of the opposing side. The topics for public forum have to do with current-day events relating to public policy. Debaters work in pairs of two, and speakers alternate for every speech. It is primarily competed by middle and high school students, but college teams exist as well. Invented in the US, public forum is one of the most prominent American debate events, alongside Policy debate and Lincoln-Douglas debate; it is also practiced in China and India, and has been recently introduced to Romania. Individuals give short speeches that are interspersed with 3 minute "Crossfire" sections, questions and answers between opposed debaters. The winner is determined by a judge who also serves as a referee. The debate centers on advocating or rejecting a position, "resolve", or "resolution", which is usually a proposal of a potential solution to a current events issue. Public Forum is designed to be accessible to the average citizen.
Parliamentary style debate, colloquially oftentimes just Parliamentary debate, is a formal framework for debate used in debating societies, academic debate events and competitive debate. It has its roots in parliamentary procedure and develops differently in different countries as a result.
A counterplan is a component of debate theory commonly expounded in the activity of parliamentary and policy debate. While some schools of debate theory require the negative position in a debate to defend the status quo against an affirmative position or plan, a counterplan allows the negative to advance a separate plan or an advocacy. It also allows the affirmative to run disadvantages against the negative.
Topicality is a resolution issue in policy debate which pertains to whether or not the plan affirms the resolution as worded. To contest the topicality of the affirmative, the negative interprets a word or words in the resolution and argues that the affirmative does not meet that definition, that the interpretation is preferable, and that non-topicality should be a voting issue. "Interpretation" is a low-level standard argued by high school debaters but not quibbled verbatim, "interpretation", by seasoned debaters beyond college. The difference is between what is said ("text") and what is allowed.
The National Forensic Association (NFA) is an American intercollegiate organization designed to promote excellence in individual events and debate. Founded in 1971, the NFA National Tournament is dedicated to a full range of literature interpretation, public address, limited preparation, and Lincoln-Douglas debate. The NFA sponsors the NFA National Tournament on an annual basis. The 2025 NFA National Tournament will be hosted by Wayne State University in Detroit, Michigan.
In all forms of policy debate, the order of speeches is as follows:
In the formal speech competition genre known as policy debate, a widely accepted doctrine or "debate theory" divides the argument elements of supporting the resolution affirmative into five subtopical issues, called the stock issues. Stock issues are sometime referred to as on-case arguments or simply on-case or case arguments as opposed off-case arguments.
Inter-collegiate policy debate is a form of speech competition involving two teams of two debaters from different colleges or universities based on a resolution phrased as something the United States federal government "should" do. Policy debate also exists as a high school activity, with a very similar format, but different leagues, tournaments, speech times, resolutions, and styles.
In debate, which is a form of argument competition, a case, sometimes known as plan, is a textual advocacy presented, in form of speech, by the Pro team as a normative or "should" statement; it is generally presented in the First Pro Constructive (1AC). A case will often include either the resolution or a rephrasing of it.
Australia–Asia Debate, sometimes referred to as Australasian Debating or Australs Style, is a form of academic debate. In the past few years, this style of debating has increased in usage dramatically throughout Australia and New Zealand as well as the broader Asian region, but in the case of Asian countries including Singapore, Malaysia, and the Philippines, the format is also used alongside the British Parliamentary Format. The context in which the Australia-Asia style of debate is used varies, but it is commonly used in Australia at the primary and secondary school level, ranging from small informal one-off intra-school debates to larger more formal inter-school competitions with several rounds and a finals series which occur over a year. It is also commonly used at university level.
A Value Premise is a component of high school Lincoln-Douglas Debate case structure. The value is usually a statement which one side is attempting to achieve throughout the debate. In general, the side that best upholds his or her value premise, which was adequately defended, wins the debate. The value premise is sometimes referred to as the "value" or simply "vp". The value premise is not to be confused with the value criterion, which is the specific means of achieving the value premise.
In Lincoln-Douglas Debate, the value criterion is the means of weighing the value premise. Unlike the value premise, the value criterion is often swayed to either the affirmative or negative side.
Public debate may mean simply debating by the public, or in public. The term is also used for a particular formal style of debate in a competitive or educational context. Two teams of two compete through six rounds of argument, giving persuasive speeches on a particular topic.
This is a glossary of policy debate terms.
Competitive debate, also known as forensics or speech and debate, is an activity in which two or more people take positions on an issue and are judged on how well they defend those positions. The activity has been present in academic spaces in the United States since the colonial period. The practice, an import from British education, began as in-class exercises in which students would present arguments to their classmates about the nature of rhetoric. Over time, the nature of those conversations began to shift towards philosophical questions and current events, with Yale University being the first to allow students to defend any position on a topic they believed in. In the late nineteenth century, student-led literary societies began to compete with each other academically and often engaged in debates against each other. In 1906, the first intercollegiate debate league, Delta Sigma Rho, was formed, followed by several others. Competitive debate expanded to the secondary school level in 1920 with the founding of the National Speech and Debate Association, which grew to over 300,000 members by 1969. Technological advances such as the accessibility of personal computers in the 1990s and 2000s has led to debate cases becoming more complex and to evidence being more accessible. Competitors and coaches have made efforts to reduce discrimination in the debate community by introducing new arguments and recruiting debaters from underprivileged communities.
