As stated by the NCFL:
Interpretation and Speech:
Dramatic Performance– Students present selections from published plays, screenplays, fictional or non-fictional work that are either serious or humorous in nature. The selections must be memorized with a maximum length of ten minutes.
Duo Interpretation of Literature – A presentation by two participants of a single selection of literature. Each performer may present one or more characters. Each character should be sufficiently developed and should interact meaningfully with the other characters. The sections must be memorized. Movement should be limited and suggested rather than exaggerated. The maximum length is ten minutes.
Extemporaneous Speaking – Each student draws three topics on current issues; chooses one and has thirty minutes to prepare a speech of a maximum length of seven minutes. Any periodical or other published material is permitted in the preparation room. Students may not refer to any written notes during the speech.
Oral Interpretation of Literature – Students present selections in two categories — prose and poetry. Each selection must be a maximum of ten minutes in length. The student must hold a manuscript and appear to be reading. The students alternate between rounds of prose and rounds of poetry.
Oratorical Declamation – Open to students in the ninth or tenth grades only. Students must use a speech or portion of a speech previously given by another person. The speech must be memorized with a maximum length of ten minutes.
Original Oratory – Students prepare original orations, usually persuasive or informative on a current topic. Any topic is permissible and any form of oration is permitted. The presentation must be memorized, with a maximum length of ten minutes.
Lincoln Douglas Debate– Individual students debating issues of values and philosophy. The NCFL Grand National Resolution is used for this competition only.
Public Forum Debate– A team event that advocates or rejects a position posed by the resolution. The focus of the debate is a clash of ideas in a persuasive manner that can be understood by a “lay” judge. Good debaters should display logic and analysis. They should use evidence when needed. They should win their case and refute that of their opponents. They should communicate effectively, using the fundamentals of good speaking. There are no burdens on either side.
Team (Policy) Debate – Two person teams using the 8-3-5 switch side format debating issues of policy. The National Resolution is used.
Student Congress – Permits students to participate in parliamentary debate. Legislation is prepared by the students in advance in the areas of Domestic, Economic, and Foreign Affairs. Students debate the merits of the legislation presented.
