Landmark's entry course, the Landmark Forum, is the default first course for new participants and provides the foundation of all Landmark's other programs. The Landmark Forum takes place over three consecutive days plus an evening session (generally Friday, Saturday, Sunday, and Tuesday evening.) Forum attendance varies in size between 75 and 250 people. Landmark arranges the course as a dialogue in which the Forum leader presents a series of proposals and encourages participants to take the floor to relate how those ideas apply to their own individual lives. Course leaders set up rules at the beginning of the program and Landmark strongly encourages participants not to miss any part of the program.
