Key Takeaways Explain This Topic AI

The Mendix Certified Intermediate Developer exam is an online proctored exam of 50 multiple-choice questions in 90 minutes, and you need at least 75% overall to pass.

Scores are reported across eight sections — Agile, Security, Microflows, Pages, Domain Model, Modules, Translation, and XPath — and there is no minimum score for any individual section.

The Rapid Developer certificate is a prerequisite for sitting the Intermediate exam, which Mendix prices at $158 USD (€148 / £124).

Mendix publishes twelve topic areas for the exam, from project roles and XPath constraints through sub-microflows, rules, system members, list operations, client notifications, multi-lingual front-ends, and anonymous users.

Exam rules are enforced by proctoring review: recording questions, using notes or a second device, or leaving the camera view nullifies the result and bars you from Mendix exams for three months.

1.1 Exam Blueprint, Format & Logistics

Exam Focus: Before you study a single microflow pattern, know exactly what this exam measures. This section covers the published exam format, the eight scored sections, the twelve topic areas named in the official Mendix exam guide, the six Academy learning paths Mendix recommends, the proctoring rules that can nullify a result, and how the rest of this guide maps onto that blueprint.

The Intermediate Developer certification is the second rung of the four-level Mendix ladder (Rapid → Intermediate → Advanced → Expert). Mendix describes the holder as someone whose knowledge and skills "extend beyond the fundamentals of the Mendix platform" — ready to build more complex features, but still taking occasional guidance from more advanced developers. That positioning drives the exam design. It is broad rather than deep , it favours "which Studio Pro setting does X" over "write this algorithm", and it repeatedly tests platform behaviour that only becomes obvious once you have actually built something.

Published Exam Format

Attribute Published value
Question count 50 multiple-choice questions
Time limit 90 minutes
Passing score 75% overall
Per-section minimum None — there is no minimum score for any individual section
Delivery Online proctored exam; webcam and microphone required
Prerequisite You must already hold the Rapid Developer certificate
Price $158 USD (€148 / £124) on the Mendix certification price list
Language English only
Retakes Permitted after a failed attempt
Results Emailed a few business days later, with the overall score and a score for each section

Mendix also publishes the preparation profile for this level: roughly 30–40 hours of self-paced Academy learning (or equivalent classroom or partner-bootcamp training), on top of about six weeks of hands-on Mendix experience .

Do not assume an expiry date. Mendix does not publish a validity period or renewal requirement for the Intermediate Developer certificate in its exam guide or on its certification pages. Treat third-party claims of a fixed "two-year validity" as unverified, and confirm current policy with Mendix Academy before you plan a recertification.

The Eight Scored Sections

The official exam guide states that the exam "is separated into the following sections", each carrying a varying number of questions:

Agile
Security
Microflows
Pages
Domain Model
Modules
Translation
XPath

Because there is no per-section minimum, one weak section cannot fail you on its own. But with only 50 questions, 13 wrong answers is the entire margin — two neglected sections are usually enough to sink an attempt. Section scores come back with your result, which makes a failed attempt genuinely diagnostic for the retake.

The Twelve Published Topic Areas

The exam guide lists the topics that are part of the exam:

Project roles & responsibilities
Constraining data with XPath
Page design with AtlasUI
Project Directory unfolded
Structuring your project with Sub microflows
Rules
System members
List operations
Client notifications
Multi-lingual front-end
Anonymous users
Security

Notice what is absent : Java actions, workflow (BPMN), OData and Data Hub publishing, performance profiling, and the Model SDK. Those belong to the Advanced and Expert levels. If you find yourself deep in a Java action tutorial, you have drifted past the blueprint.

Recommended Preparation Paths

Mendix recommends attending the Intermediate Developer course or a Mendix Bootcamp, or completing these Intermediate learning paths in the Academy:

Learning path Blueprint sections it feeds
Unlocking True Collaboration Agile, Modules
Constrain Your Data Using XPath XPath, Security
Create an App with Advanced Page Building Pages, Translation
Building an Event App Using Microflows Microflows
Expand Your Domain Modeling Skills Domain Model
Importing and Exporting Your Data Modules, Microflows
How This Guide Maps to the Blueprint

Guide chapter Blueprint coverage

Chapter 1 — Exam blueprint, agile roles, project directory, modules, version control Agile, Modules, Project Directory unfolded

Chapter 2 — Advanced domain modeling Domain Model, System members
Chapter 3 — XPath constraints and retrieval XPath, Constraining data with XPath
Chapter 4 — Advanced microflows Microflows, Sub microflows, Rules, List operations, Client notifications
Chapter 5 — Atlas UI, dynamic behaviour, translation Pages, Page design with AtlasUI, Multi-lingual front-end
Chapter 6 — Application security Security, Anonymous users
Chapter 7 — REST and SOAP integration Importing and exporting your data (adjacent)
Chapter 8 — Mobile and nanoflows Adjacent background; not a published exam section
Chapter 9 — Debugging, quality, operations Cross-cutting delivery practice; not a published exam section

Chapters 1–6 carry the scored blueprint end to end. Chapters 7–9 are included deliberately, because Mendix delivery work demands them and because they reinforce the microflow, page, and security behaviour that is scored — but if you are short on revision time, finish Chapters 1–6 first.

Proctoring Rules That Nullify Results

The exam is delivered through a proctored testing platform and recordings are reviewed by Mendix Academy. A violation does not merely cost you the attempt: results are nullified, you are barred from any Mendix exam for three months , and your employer is informed. The published prohibitions include:

Recording the exam in any form — screenshots, photographs, video, or copying text
Using notes, physical or virtual, or any document of questions and answers
Using electronic devices; phones and tablets are detected in your workspace
Wearing headphones or ear plugs
Navigating away from the test window, or using a browser search engine
Using a second monitor or a second computer
Having anyone else present, or reading questions out loud
Leaving the desk for longer than two minutes, or moving out of camera view

Practical setup: one monitor only, a working webcam and microphone, a quiet room, and a system-compatibility check run days in advance rather than minutes before. Budget 15 minutes for login. Your personal exam link arrives by email, cannot be forwarded to another address, and expires after one month.

A Study Plan That Matches the Blueprint

Build, do not just read. Almost every question is a Studio Pro scenario. Model each topic once in a scratch app — an entity with an access rule, a snippet, a sub-microflow, a Batch Translate run.

Weight revision by section, not by interest. Eight sections, one overall threshold: the hour you have spare belongs to your weakest section, not your favourite one.

Memorise the settings vocabulary. On-delete wording, security levels, error-handling names, data-source options, and log levels are all named things the exam quotes verbatim.

Practise reading distractors. Options are long and plausible; the wrong ones usually invert exactly one word — owner versus non-owner, client versus server, rollback versus without rollback.
