  abstract  = {Rubrics are the primary reference for manual scoring of constructed
               responses, and there is growing interest in their use in automated
               scoring methodologies. In this work, we propose Aspect-Grounded
               Rubric{--}Answer Alignment (AGRAA), a rubric-based end-to-end
               scoring framework that models rubric descriptors as latent aspect
               spaces. Concretely, rubric descriptors are represented as low-dimensional
               subspaces derived from contextualised transformer embeddings,
               and student responses are scored according to how strongly their
               representations align with these rubric-induced spaces relative
               to the residual space outside them. This formulation provides
               a geometrically grounded interpretation of rubric-based scoring
               while enabling end-to-end training with standard transformer encoders.
               We introduce three distinct architectural variants and evaluate
               them on multiple short-answer and essay scoring datasets. Across
               these tasks, AGRAA achieves predictive performance highly competitive
               with strong neural and feature-based baselines. In addition, the
               framework yields interpretable intermediate representations that
               expose which rubric-defined aspects contribute to scoring decisions,
               enabling decision-aligned explanations grounded in rubric descriptors.}
