MongoDB Certification in 2026
Status, Cost, and All Four Exams Compared
Is the MongoDB certification still a thing? Yes - four Associate exams at $150 each. The confusion comes from old exam codes that practice-test sites keep alive. Here's the current program, the real costs, and the cheaper alternatives.
MongoDB is the default document database for a huge share of modern application stacks, and MongoDB skills show up across backend, full-stack, and data engineering job postings. Unlike some technologies - Redis's certification took a two-year hiatus - MongoDB's certification program has stayed alive and current.
What creates confusion is the naming history. If you search for MongoDB certification, you'll hit a wall of pages about "C100DEV" and "C100DBA" exams - codes from an earlier iteration of the program that practice-test and exam-dump sites keep alive years later. The current program is simpler: four Associate-level exams, $150 each, registered and taken through MongoDB University. This guide covers all four, what they actually cost over time, and the lower-cost alternatives.
The short version
Is the MongoDB certification still active?
Yes. Four current exams: Associate Developer, Associate Database Administrator, and two newer specialist exams (Data Modeler and Atlas Administrator). All $150, online, live-proctored. The "C100DBA" pages you'll find elsewhere refer to the program's earlier exam codes - see the C100 confusion explained.
Most recognised MongoDB credential
The Associate Developer for application engineers, the Associate DBA for operations roles. Both carry the MongoDB vendor brand. Budget realistically: $150 per attempt with no retake included, and plan for recertification (validity is generally cited as three years).
Cheapest verifiable MongoDB credential
TrueCert's MongoDB track: a free Introduction assessment to start, then Fundamentals at $14.99 and Professional at $29.99 - each with a verifiable Open Badges 2.0 certificate, one free retake included, and no expiry. The full track costs less than a third of one official exam attempt.

MongoDB Associate Developer
Intermediate Best overallThe Associate Developer is MongoDB's flagship certification for application engineers: roughly 60 multiple-choice questions covering CRUD operations, the aggregation framework, indexing, data modeling, drivers and tools, plus transactions and search. It's language-aware - you take it with a focus track (Node.js, Python, Java, and more) matching your stack - delivered online with live proctoring, in English.
The domain weighting rewards real usage: CRUD and aggregation together make up roughly 40% of the exam, and the aggregation questions in particular punish anyone who has only done tutorial-level work. $150 buys one attempt - there's no included retake, so a failed attempt is another $150. Preparation is free via MongoDB University's courses and official practice questions.
MongoDB Associate Database Administrator
IntermediateThe Associate DBA exam is the operations-side counterpart: server administration, monitoring, security, replication, backup and recovery, plus the shared foundation of CRUD and indexing. This is the successor to the skill set the old "Certified DBA Associate" (C100DBA) tested, in the current program's format.
If you're searching for the status of the MongoDB DBA certification: this is it, alive and bookable at learn.mongodb.com for $150. Same mechanics as the Developer exam - online, live-proctored, no retake included. For DBAs, DevOps engineers, and SREs who own MongoDB infrastructure, it's the vendor credential that matches the role.
MongoDB Associate Data Modeler & Atlas Administrator
SpecialistThe program's two newer specialist exams round out the lineup. The Associate Data Modeler focuses entirely on schema design for the document model - embedding vs referencing, workload-driven design, and the patterns and anti-patterns that decide whether a MongoDB deployment performs or degrades. The Associate Atlas Administrator covers MongoDB's cloud platform: Atlas deployment administration, security, backup and recovery, monitoring, and maintenance.
Both are $150 with the same delivery mechanics. Worth noting before booking: these are sharper, narrower credentials than the Developer/DBA pair. The Data Modeler is arguably the most skill-dense exam in the program (schema design is where real MongoDB expertise shows), while the Atlas Administrator is specific to MongoDB's commercial cloud - highly relevant if your employer runs Atlas, less so for self-managed deployments.
TrueCert MongoDB Fundamentals (L1)
Beginner Best valueTrueCert MongoDB Fundamentals is a timed, 20-question assessment covering the MongoDB core: the document model, CRUD operations, query operators, and indexing basics. There's also a free Introduction assessment if you want to benchmark yourself before spending anything at all.
Passing produces a shareable, publicly verifiable certificate: a verification token employers can check against TrueCert's public API, plus an Open Badges 2.0 credential for LinkedIn. Where the official exam costs $150 per attempt and needs recertification, this is $14.99 once, includes a free retake, and never expires. The assessment uses 8 question types including code output prediction, so it tests whether you can reason about MongoDB behaviour rather than recall trivia. Many candidates use it as a low-stakes benchmark before committing $150 to the official exam.
TrueCert MongoDB Professional (L2)
IntermediateMongoDB Professional is the production-grade level: a timed, 25-question, scenario-based assessment covering the skills real application and platform work demands - schema design decisions (embedding vs referencing, workload-driven modeling), aggregation pipelines, indexing strategy, and operational concerns like replication behaviour.
The topic overlap with the official Associate Developer and Data Modeler exams is deliberate: this is the same knowledge, verified at a fraction of the price. Same certificate mechanics as Fundamentals - verifiable token, Open Badges 2.0, one free retake, no renewal fee.
MongoDB University Courses
Free Official exam prepMongoDB University is one of the better vendor training platforms: free, self-paced learning paths that map directly to each certification exam, including hands-on labs and official practice questions. If you're taking any of the official exams, this is the preparation route - it's maintained by MongoDB and it's free.
As with every vendor academy: completing a learning path earns a certificate of completion, which is proof of attendance rather than a certification. The credential still costs $150. If the vendor badge isn't a requirement, pairing the free courses with a low-cost verifiable assessment gets you checkable proof for a tenth of the price.
The C100DEV / C100DBA confusion, explained
Search for "MongoDB certification" and you'll find an entire ecosystem of pages about the C100DEV (Certified Developer Associate) and C100DBA (Certified DBA Associate) exams - many updated this year, most of them practice-test and exam-dump sites. This is why so many people end up searching for the certification's "status".
The short answer: those codes date from the earlier iteration of MongoDB's certification program. The program itself never went away - it was revamped into the current Associate lineup (Developer, Database Administrator, Data Modeler, Atlas Administrator), registered through MongoDB University rather than a separate exam portal.
Practical implications: register only at learn.mongodb.com, treat third-party material sold under the old C100 codes with suspicion (much of it targets old exam content - some explicitly says "based on MongoDB 4.4", several major versions behind), and prefer MongoDB's own free courses and practice questions for preparation.

Frequently asked questions
Is the MongoDB Certified DBA certification still available in 2026?
Yes. MongoDB's certification program is active, and DBA skills are covered by the current Associate Database Administrator exam ($150, online proctored). The confusion comes from the old C100DBA exam code, which dates from an earlier iteration of the program and lives on across third-party practice-test sites. Registration for the current exams happens through MongoDB University at learn.mongodb.com.
How much does a MongoDB certification cost?
$150 USD per exam. MongoDB offers four Associate-level certifications - Developer, Database Administrator, Data Modeler, and Atlas Administrator - all priced at $150, delivered online with live proctoring, in English. A failed attempt means purchasing a new exam.
How long is a MongoDB certification valid?
MongoDB Associate certifications are generally cited as valid for three years, after which you recertify by passing the current version of the exam. Check the specific exam page at learn.mongodb.com for the current policy before booking.
What is the difference between C100DEV/C100DBA and the current MongoDB exams?
C100DEV and C100DBA are exam codes from the earlier version of MongoDB's certification program. The program has since been revamped into the current Associate lineup (Developer, Database Administrator, Data Modeler, Atlas Administrator). Many practice-test and exam-dump sites still sell material under the old codes, which is why searches for them remain common - but current registration and content live at learn.mongodb.com.
What is the cheapest way to get a verifiable MongoDB credential?
TrueCert's MongoDB track: a free Introduction assessment, MongoDB Fundamentals at $14.99, and MongoDB Professional at $29.99. Each paid assessment includes one free retake, produces a publicly verifiable Open Badges 2.0 certificate, and never expires. The official MongoDB exams carry the vendor brand but cost $150 per attempt.
