Assessment as Code (Layers)

“Assessment as Code”

ColabEdu resolved the technical crisis of monolithic LLMs by applying fundamental software engineering principles: the MVC (Model-View-Controller) pattern and Dependency Injection. We fragmented the assessment monolith into an atomic, versionable, and immutable “Layer Graph” (C0, C1, C2, C3).

The Layer Graph (YAML) Explained

• Layer C0 (Standards / The Law): Vectorized dictionaries of pure rubrics (e.g., LOMLOE, AP, IB). They act as the immutable “Constitution” of the system.
• Layer C2 (Context / Realia): The “Semantic Ground”. Pre-processed news articles or literature for Retrieval-Augmented Generation (RAG).
• Layer C3 (Directives / The Teacher): Override rules, pedagogical tone, and individual curricular adaptations.
• Layer C1 (Recipe / The Pedagogical Recipe): The instance that parameterizes and orchestrates the other layers. It specifies the ExerciseType (UI/engineering contract) to use and injects the law (C0), context (C2), and directives (C3).
