You’re probably wondering why Extanto has been focusing so much attention on AI as of late. Oh, sure, it’s been in the news, and businesses are discovering ways to incorporate its strengths into their workflows. And so have we. Extanto has launched a new service designed to reshape how textbook publishers create test bank materials for higher education. This offering blends expert-led prompt engineering with advanced generative AI to produce assessment content that is pedagogically sound, intellectually rigorous, and customized to the instructional priorities of each client.
We begin with a secure, closed-loop workflow in which publishers provide proprietary instructional materials—textbooks, course outlines, and related teaching resources—directly into a private instance of ChatGPT. These materials are never used for AI training or model refinement and remain entirely confidential throughout the pipeline. Subject matter experts on the Extanto team analyze the instructional inputs and craft custom prompts that align with the pedagogical framework of the content. The AI then uses these prompts to generate test bank questions across a variety of problem types, including multiple choice, open response, short answer, true/false, matching, and applied scenario-based formats.
Using the the Socratic method, the AI is directed to build assessments and rejoinders that encourage students to reflect, analyze, and justify their thinking. Rather than focusing solely on factual recall, questions and rejoinders both are designed to stimulate reasoning, reveal conceptual understanding, and surface misconceptions. The result is a test bank that functions not just as an evaluation tool, but as an extension of and enhancement to the learning experience.
Once the AI has generated a draft set of questions and responses, the content is handed off to Extanto’s QA team for review. The team—all of whom have instructional design or teaching experience—evaluate each item for technical accuracy, pedagogical coherence, and alignment with client standards. Revisions are made where necessary to preserve clarity, correct errors, and match the tone and structure preferred by each publisher. The editing process is transparent, with annotated changes and comments available to clients who want insight into the refinement process from prompt to polished product.
This service allows publishers to scale content development efficiently without sacrificing quality or control. It supports parallel workflows with textbook production and accommodates tight deadlines, allowing editorial teams to meet release targets while expanding the range and depth of the assessment materials they provide. Publishers looking to differentiate their offerings through more sophisticated and reflective evaluation tools, will find this hybrid model—combining human expertise with intelligent automation—a compelling path forward.
Extanto’s approach doesn’t attempt to replace educators or editorial professionals; rather, it builds an infrastructure in which their knowledge is amplified and their time is preserved for high-value work. With this service, test banks become just faster to produce, and meaningfully better in how they serve teaching and learning in the modern classroom.
