Test content development has traditionally been a labor-intensive process, relying heavily on subject matter experts (SMEs) to create high-quality, defensible exams. While this ensures rigor, the approach often lacks scalability and the ability to adapt quickly to new standards in fast-evolving fields. PSI and Memorang have collaborated to offer a transformative solution: empowering testing programs to train and evolve their own "AI box," a system that enhances the efficiency and scalability of content generation while preserving critical human oversight. This innovative approach evolves the role of SMEs from authors to architects, enabling them to guide and refine AI systems that improve over time through human oversight, feedback, and data. Testing programs can modernize their internal processes, generate high quality standards-aligned items more efficiently, and seamlessly integrate AI-powered test prep, assessment, and feedback. These solutions not only reduce content development time but also foster personalization and data-driven insights to better support test takers.
