Professional developers and advanced builders who design, build, and operate agents in Microsoft Copilot Studio.

Exam Format

120 minutes, delivered in English, passing score 700 out of 1000. Three domains, no formal prerequisite.

Key Focus Areas

Agent planning and governance, topics and agent flows, enterprise knowledge, tools and MCP, multi-agent collaboration, evaluation, and lifecycle management.

Integration Heavy

Integrating and extending agents is 40 to 45 percent of the exam, the single largest domain. Hands-on time in Copilot Studio matters more than reading.

Where AB-620 fits in the Microsoft AI track

AB-620 is one of the newer Microsoft AI certifications, so it is worth being clear about what it is and what it is not:

  • Nothing retires because of it. AB-620 became generally available in late June 2026 as a new Associate-level exam. There is no predecessor being withdrawn and no transition deadline to plan around.
  • It is a builder exam, not an adoption exam. AB-730 covers using Microsoft 365 Copilot well. AB-620 asks you to design, build, integrate, and manage the agents that other people then use.
  • Microsoft Copilot Studio is the centre of gravity. Every domain assumes you have spent real time in the product, configuring topics, agent flows, tools, and channels.
  • Integration carries the most weight. Domain 2, integrating and extending agents, is 40 to 45 percent of the scored content, so knowledge sources, tools, and multi-agent patterns deserve the bulk of your revision.

What is the Microsoft AB-620 Exam?

The Microsoft AB-620 exam, officially titled Designing and Building Integrated AI Solutions in Copilot Studio, leads to the AI Agent Builder Associate certification. It is aimed at professional developers and advanced builders who create agents in Microsoft Copilot Studio and connect them to enterprise data, tools, and other agents.

The certification validates the full build lifecycle. You plan an agent solution and its integration, identity, channel, responsible AI, and governance requirements, then configure topics and agent flows, ground the agent in enterprise knowledge, extend it with tools including Model Context Protocol servers and custom connectors, orchestrate multi-agent collaboration, and finally evaluate performance and move the solution between environments with Power Platform application lifecycle management. The exam runs for 120 minutes, is delivered in English, and the passing score is 700 out of 1000.

Who Should Take the AB-620 Exam?

Copilot Studio Builders

Makers already shipping agents who want a credential that proves they can integrate, secure, and operate them at enterprise scale.

Power Platform Developers

Developers working with Power Fx, Dataverse, and solutions who are moving from apps and flows into agent development.

Integration Engineers

Engineers wiring agents into REST APIs, custom connectors, MCP servers, and line-of-business systems across an organisation.

AB-730 Graduates

Candidates who know Microsoft 365 Copilot from the user side and want an Associate-level credential that proves they can build for it.

Knowledge Microsoft Assumes You Already Have

AB-620 has no formal prerequisite, but it is written for experienced builders. The exam does not stop to teach any of the following:

  • Power Fx expressions and Dataverse tables, columns, and relationships
  • Power Platform environments and how solutions move between them
  • Microsoft 365 Copilot and how agents surface inside it
  • Microsoft Foundry, including its models and agents
  • Adaptive cards for structured, interactive responses
  • Intermediate generative AI concepts including RAG, MCP, and A2A

Exam Objectives Breakdown

AB-620 covers three domains. Integrating and extending agents carries the most weight by a clear margin, reflecting how much of real agent work is connecting knowledge, tools, and other agents together.

Copilot Studio Technologies to Know

AB-620 is built around Microsoft Copilot Studio and the services an enterprise agent connects to. Concentrate your hands-on study on these six areas.

Microsoft Copilot Studio

The authoring surface for agents: topics, tools, channels, publishing, and the generative answers node. Usage is billed through Copilot Credits.

Agent Flows

Deterministic automation alongside conversational topics, with actions, connectors, parameters, error handling, human-in-the-loop steps, and run monitoring.

Enterprise Knowledge

Copilot connectors, Power Platform connectors, and Azure AI Search indexes used to ground answers in your own organisation data.

Tools and MCP

Computer use, Model Context Protocol tools over Streamable HTTP, custom connectors, and direct REST API calls that give an agent the ability to act.

Multi-Agent Collaboration

Connected agents, Microsoft Foundry agents, Fabric data agents, and the A2A protocol for interoperability between agents built on different platforms.

ALM and Observability

Solutions, environment variables, and Power Platform Pipelines for promotion between environments, plus Application Insights for telemetry.

Frequently Asked Questions

What is the AB-620 exam?
AB-620, officially titled Designing and Building Integrated AI Solutions in Copilot Studio, leads to the AI Agent Builder Associate certification. It is an Associate-level Microsoft exam for people who build agents in Microsoft Copilot Studio, covering three domains: planning and configuring agent solutions, integrating and extending agents, and testing and managing them. The exam runs for 120 minutes, is delivered in English, and the passing score is 700 out of 1000.
Does AB-620 replace a retiring exam?
No. AB-620 is a new certification that became generally available in late June 2026, and it does not replace or retire an earlier exam. There is no predecessor to migrate from, no legacy credential that expires when you pass, and no transition path you need to take before a deadline. If you already hold AB-730 or another Microsoft AI certification, AB-620 sits alongside it as a builder-focused credential rather than a renewal of it.
How is AB-620 different from AB-730?
AB-730 AI Business Professional is about using Microsoft 365 Copilot well: prompting, everyday productivity scenarios, and applying generative AI across business tasks. AB-620 is about building. It is an Associate-level developer exam that asks you to plan an agent solution, configure topics and agent flows, connect enterprise knowledge, add tools, orchestrate multiple agents, and manage the whole thing through evaluation and application lifecycle management. The two exams share Copilot vocabulary but test very different skills, and AB-620 assumes hands-on time in Copilot Studio, Dataverse, and the Power Platform.
Are there prerequisites for the AB-620 exam?
There is no formal prerequisite, but Microsoft targets AB-620 at professional developers and advanced builders and assumes a fair amount of background. You should be comfortable with Power Fx, Dataverse, and Power Platform environments, understand how agents surface in Microsoft 365 Copilot, have used Microsoft Foundry, and be able to design adaptive cards. Intermediate generative AI knowledge is assumed too, including retrieval augmented generation, the Model Context Protocol, and agent-to-agent communication.
What is the passing score for AB-620?
The passing score is 700 out of 1000, in line with other Microsoft role-based certifications. That is not a straight 70 percent, because Microsoft scales scores according to the difficulty weighting of the questions you receive across the three domains. Treat 700 as the floor rather than the target, and aim to score comfortably above it on full-length practice tests before you book.
How long should I study for the AB-620 exam?
If you already build agents in Copilot Studio regularly, four weeks of consistent study is a realistic target, with most of that time spent on the integration domain. If Copilot Studio is newer to you, or you have not worked with Copilot connectors, MCP tools, or multi-agent patterns, allow six weeks and spend more of it inside the product rather than reading. The four-week plan on this page tracks the official domain weights so your revision time matches where the marks are.
Is there an official Microsoft practice assessment for AB-620?
Not yet. Some Microsoft certifications ship with a free practice assessment on Microsoft Learn, but at the time of writing AB-620 does not have one. Until Microsoft publishes one, your best preparation is hands-on building in Copilot Studio, working through the Microsoft Learn documentation for each objective, and sitting full-length practice tests such as ours to rehearse timing and question formats.
Which technologies does AB-620 focus on?
Microsoft Copilot Studio is the centre of the exam: topics, agent flows, tools, channels, and publishing. Around it you need Copilot connectors and Power Platform connectors for knowledge, Azure AI Search for grounded generative answers, the Model Context Protocol over Streamable HTTP and custom connectors for tools, connected agents alongside Microsoft Foundry agents, Fabric data agents and the A2A protocol for multi-agent work, Application Insights for telemetry, and Power Platform solutions, environment variables, and pipelines for lifecycle management.
