Rubric Evaluation in Microsoft Foundry: A Structured Approach to AI Model Assessment
Views (3)
Introduction In this blog, I’m going to introduce a powerful new capability in Microsoft Foundry called Rubric Evaluation. This feature enables developers and AI engineers to evaluate model outputs using structured, criteria-based scoring instead of relying only on simple pass/fail or similarity checks. Here’s a hands-on overview of how Rubric Evaluation works and why it’s becoming an essential part of AI development workflows. Public preview: Recently introduced in Microsoft Foundry (2026) General availability: Available since June 2026 Problem Statement As AI applications grow more advanced, evaluating their outputs has become increasingly complex. Traditional evaluation methods such as exact match checks, keyword comparison, or even basic semantic similarity often fall short when dealing with: •Subjective responses (e.g., explanations, summaries) •Multi-step reasoning outputs •Creative or open-ended answers •Context-aware conversational responses This creates a challenge: How do we evaluate AI responses in a consistent, structured, and human-like way while maintaining scalability and automation? Solution: Rubric Evaluation in Microsoft Foundry Microsoft Foundry introduces Rubric Evaluation, a structured evaluation approach where AI outputs are assessed against predefined criteria (rubrics) rather than simple correctness checks. A rubric defines what “good” looks like by breaking evaluation into multiple dimensions such as: •Accuracy •Completeness •Clarity •Relevance •Tone or style •Reasoning quality Instead of just saying “correct” or “incorrect,” the model is scored across these dimensions, providing richer insights into performance. Key Benefits of Rubric Evaluation 1. Structured evaluation: Breaks down responses into measurable criteria instead of binary outcomes. 2. Human-like assessment: Mimics how humans evaluate answers . 3. Better debugging: Helps identify why a response failed, not just that it failed. 4. Flexible and customizable: You can define rubrics tailored to your use case (chatbots, summarization, Q&A, etc.). 5. Works well with LLM-based evaluation: Rubric scoring can be performed using LLM evaluators for scalable automation. How Rubric Evaluation Works Step 1: Create an Evaluator 1. Go to the Microsoft foundry portal and then click on the evaluations section on the left side panel and then click on the Create evaluator button as shown in the below picture. 2. Once Create evaluator window opens, fill in the required details, including the evaluator name, display name, and description. Then, set the evaluator type to “Rubric”. 3. Next, select a suitable model from the available options. Choose the model that best matches your evaluation requirements and is supported for rubric-based evaluation. 4. Select the agent you want to use for the evaluation. In this example, I have two agents available, so I will choose the Leave Policy Agent. 5. After configuring the required settings, click Generate rubric to start creating the rubric based on the selected evaluator setup. javascript:”javascript:”javascript:” writer.editor.GO_TO_TOP … Continue reading Rubric Evaluation in Microsoft Foundry: A Structured Approach to AI Model Assessment
