Simulating Success: An AI-Powered DECA Judge for Realistic Practice

Preparing for DECA competitions often means practicing alone, imagining questions, and hoping feedback from teachers or peers is enough. After building my original Scenario Generator, I wanted to take practice one step further. The result was an interactive AI system that simulates real DECA judges and creates a complete role-play experience that feels realistic, challenging, and personalized.

This system allows students to engage in real-time conversations with an AI judge powered by OpenAI’s latest API. Instead of rehearsing scripted answers, users respond dynamically to follow-up questions, just like in an actual DECA event. This transforms practice from a passive activity into an active simulation where thinking on your feet is required.

One of the most valuable features of the system is its personalized feedback. After each interaction, the AI evaluates presentation skills, content accuracy, professional presence, and overall communication. Rather than giving generic advice, it provides specific suggestions for improvement tied directly to DECA performance indicators. This helps students understand not only what to improve, but why it matters in a competitive judging environment.

The tool also includes a role-switching feature. Students can observe the AI demonstrate high-quality responses, modeling what strong answers sound like in terms of clarity, structure, and professionalism. This is especially helpful for students who learn best by example and want to see what excellence looks like before attempting it themselves.

Beyond surface-level feedback, the system offers a comprehensive evaluation of business acumen and communication skills. It assesses how well users apply business concepts, justify decisions, and communicate ideas under pressure. These are skills that matter not only in DECA competitions, but also in real-world professional settings.

By simulating real judges and providing immediate, targeted feedback, this AI system turns individual practice into an immersive learning experience. It bridges the gap between preparation and performance, helping students build confidence, adaptability, and critical thinking skills before they ever step into a competition room.
