Current Exam Facts for AI-300

Quick Answer: Exam AI-300: Operationalizing Machine Learning and Generative AI Solutions is the single exam that earns Microsoft Certified: Machine Learning Operations Engineer Associate. In the United States it costs US$165 (the price varies by country or region). You pass with 700 or greater on a 1–1,000 scaled score—not a raw 70 percent. Microsoft does not publish an AI-300-specific question count; typical role-based exams contain 40–60 questions. Associate and expert exams without labs use 100 minutes of exam duration and 120 minutes of seat duration; the AI-300 certification page currently says you will have 120 minutes to complete this assessment. The exam is offered in English, delivered through Pearson VUE, proctored, and may include interactive components.

What this credential is

AI-300 is an intermediate, associate-level Microsoft role-based exam. Passing it is how you earn Microsoft Certified: Machine Learning Operations Engineer Associate. There is no second exam in the path. Microsoft describes the job as setting up infrastructure for machine learning operations (MLOps) and generative AI operations (GenAIOps) on Azure, together called AI operations (AIOps).

That pairing is the exam’s identity. You are not only a classic Azure Machine Learning operator, and you are not only a playground prompt author. You design, deploy, monitor, and optimize two production stacks: traditional models on Azure Machine Learning and generative applications and agents on Microsoft Foundry.

The products the official study guide puts in scope are Azure Machine Learning (SDK and CLI v2), Microsoft Foundry, GitHub Actions, Bicep, Azure CLI, and MLflow. Later chapters teach those products in blueprint order. This section is the logistics layer: what you buy, how you are scored, how long you sit, and what happens if you fail or if you pass and the year runs out.

Cost, language, and how you schedule

Microsoft’s certification FAQ states that associate and expert exams typically cost US$165 and are priced according to currency values in specific countries and regions. Confirm the live price on the exam page when you schedule. A voucher, Exam Replay bundle, or employer billing code does not change the published fee; it only changes who pays it.

Microsoft strongly recommends registering with a personal Microsoft account (MSA). If you register with an organizational Microsoft Entra ID (work or school) account and later leave that organization, exam records can be lost and unrecoverable. Create or use a personal MSA before you pick a Pearson VUE slot.

Scaled scoring: 700 is not 70 percent

All Microsoft technical exams report scores on a scale of 1 to 1,000. A passing score is 700 or greater. Microsoft is explicit that because this is a scaled score, it may not equal 70 percent of the points. The cut score is based on the knowledge and skills needed to demonstrate competence and on the difficulty of the questions on your form.

Hold these scoring rules as facts, not folklore:

• Easier forms require more raw points to pass; harder forms require fewer. That is why a simple percent-correct number would not help you gauge success across retakes.
• On most multi-part items you receive one point per correctly answered component. You can earn all, some, or none of the points. If an item is worth more than one point, the question text says so.
• There is no penalty for guessing. An incorrect answer simply earns no point; nothing is subtracted.
• Some questions may be unscored. Microsoft uses them to gather data before they meet psychometric standards. You will not know which items are unscored, so answer every question as if it counts.
• Alternate scoring approaches for newer item types are called out in the question text when they apply.

For most exams you see a result within minutes, plus a report with overall score, pass/fail, and a bar chart by skill area. Exams that include labs take about 30 minutes to score; the score is in your Microsoft Learn profile within 24 hours. Microsoft does not tell you which questions you missed. The bars show relative strength and weakness. Shorter bars are weaker areas. You cannot add the bars together to reconstruct 70 percent, and you cannot convert a bar into a count of missed items. Some skill areas have only a few questions; a weak showing there can even display as a zero without meaning you missed a huge share of the whole exam.

Common trap: treating 700 as “get 70 percent right,” then inventing a raw target such as 42 of 60, or treating each skills-measured percentage as a fixed item count. Microsoft does not publish an AI-300 item table. The five domain percentages are blueprint weights, not a seating chart for your form.

Time: exam duration versus seat duration

Microsoft publishes two clocks. AI-300 currently surfaces both ideas on two different official pages. You must keep both; do not collapse them into a single made-up number.

Exam duration is the time you have to complete the exam questions. Seat duration is the appointment block you should allocate: reviewing instructions, reading and accepting the Microsoft Certification Exam Candidate Agreement, completing the questions, and optionally leaving comments afterward.

Microsoft’s exam-duration page lists these role-based figures:

• Associate and expert role-based exams without labs: 100 minutes exam duration, 120 minutes seat duration.
• Associate and expert role-based exams that may contain labs: 120 minutes exam duration, 140 minutes seat duration.
• Fundamentals exams: 45 minutes exam duration, 65 minutes seat duration (AI-300 is not a fundamentals exam).

Microsoft does not publish a list of exams that currently include labs, because labs can be removed at any time for Azure outages, bandwidth, or similar issues. When you register, Pearson VUE shows the time for your appointment. When you launch, read the overview screens. This guide does not invent labs for AI-300.

The AI-300 certification page currently states: “You will have 120 minutes to complete this assessment.” That page also says the exam will be proctored, that you may have interactive components to complete, and that you should read the duration article for the full experience. Interactive components are not automatically hands-on Azure labs. Treat 120 minutes as the wording on the certification page (seat-time language for a role-based exam) and treat 100/120 as the duration-page pair for associate exams without labs. If your registration confirmation shows a different pair, believe the confirmation and the launch overview—not a blog post.

Use the exam sandbox at aka.ms/examdemo before test day. Microsoft will not identify the exact mix of item types in advance. The sandbox is how you meet multiple choice, drag-and-drop, build list, hot area, case studies, mark-for-review, the timer, and the candidate agreement without burning paid attempts.

Unscheduled breaks

You may take unscheduled breaks on role-based exams without requesting an accommodation in advance:

• Five minutes have been built into exam time for breaks; Microsoft removed questions to make room.
• The exam clock continues while you are on break. You may take longer than five minutes or take multiple breaks, but unused exam time is gone. If time ends during a break, you are scored on what you completed.
• After you start a break, you cannot return to questions you already viewed, even if they are unanswered or marked for review.
• You cannot break in the middle of a lab or a problem-solution set. You may break before or after those item types, and you may break during a case study, but you still cannot return to questions already seen.
• Leave camera view only after you start the break in the exam UI. Accessing unauthorized materials on break revokes the exam.

Microsoft Learn during the exam

Because AI-300 is an associate role-based exam (not a fundamentals exam and not a GitHub exam), you can open Microsoft Learn from the left navigation in a split screen. Extra time is not added. The exam timer continues while you browse. You can use content on the learn.microsoft.com domain except Q&A, practice assessments, and your profile. Links that leave the Learn domain are blocked. Use in-page find (Ctrl+F on Windows or Command+F on a Mac) on a Learn page; that find does not search the exam window, and closing Learn resets search history.

Treat Learn as a lookup for a flag, SKU, YAML key, or evaluator name you already understand. If you search every item, you will not finish in the allotted time, and Microsoft says that is by design.

Prerequisites, retakes, and renewal

No prior exam is required. Microsoft does not gate AI-300 behind AZ-900, AI-900, DP-100, or a GitHub certification. The published candidate profile expects hands-on Azure Machine Learning and Microsoft Foundry experience, Python, and entry-level DevOps practices including GitHub Actions and command-line interfaces. Recommendation is not a prerequisite.

Retake policy for this paid role-based exam:

1. If you do not pass the first time, wait 24 hours before retaking.
2. A 14-day waiting period applies between all subsequent attempts (up to five).
3. You may not take a given exam more than five times within a 12-month period from the first attempt. After five fails, you are eligible again 12 months from the date of the first attempt.
4. You cannot retake an exam you have passed unless the certification has expired.
5. You must pay to retake the exam if a fee applies.

Waiting-period waivers exist only when you had internet connectivity issues or equipment failure, a Pearson VUE case was opened, and you include that case number. “I was close” is not a waiver reason.

Renewal: associate, expert, and specialty certifications expire after one year (fundamentals do not expire). During a six-month eligibility window you can take a free, unproctored, open-book renewal assessment on Microsoft Learn. Passing extends the certification one year from the expiration date, not from the calendar day you pass. There is no limit on renewal assessment retakes until the certification expires; if you do not pass, you can try again immediately, and after the second try you wait at least 24 hours between future attempts.

Realistic scenario

Jordan books AI-300 on a work Entra ID, treats 700 as 70 percent, plans to skip generative domains “because they are only 10–15 percent,” and intends to live in Microsoft Learn for every YAML question. That plan already contains three independent failures: an account that can vanish with a job change, a scaled-score misconception, and a Learn-as-textbook strategy that burns the exam clock. Register with a personal MSA, study all five domains, and use Learn as a scalpel.
