Researchers have developed TeachMateGPT, a novel multi-agent framework designed to generate pedagogical assessment items from science curriculum materials. This system addresses limitations in existing retrieval-augmented generation (RAG) approaches by employing a hierarchical knowledge base called COPE, which segments documents according to syllabus structure and links evidence at multiple granularities. TeachMateGPT also features a staged agent pipeline with fail-closed routing and a specialized retrieval fusion mechanism to ensure sufficient evidence before generation. Additionally, it incorporates SAVER, a source-attributed verification protocol to score faithfulness and relevance, and has been validated on the NCTB-SciGen8 dataset, demonstrating significant improvements in faithfulness and answer relevancy compared to a standard RAG baseline.
