The overlay theory defines multiple sources of evidence available to the diagnostic module for its update of the overlay model: Structural evidence is retrieved from a syllabus in the form of a network of dependencies and relative complexities among the skills, along the lines of BIP's Curriculum Information Network. This network provides the notion of a frontier of the student's knowledge, where teaching should concentrate. Since it is where learning is likely to occur, variations taking place far from the frontier should be treated with caution.
