Abstract: A system for computer-based training (“CBT”) includes a content editing portal, operable on a computer system, for generating content using a markup language, the portal providing a graphical user interface (“GUI”) to give a user access to the markup language date in a structured form-based editing environment. The portal supports: making changes to the content; creating an index of the content; associating a procedure with a page of content; adding audio to the content; and adding titles to the content. An acronyms module supports the creation of a list of acronyms; and a testing module which supports the creation of tests. Content is stored using templates, and the GUI supports reassigning the content from a first template to a second template by selection of a template tab corresponding to the second template. A presentation mechanism presents a lesson to a user, the lesson having been stored using structural templates including at least one lesson template and at least one testing template.
