Best Data Engineering Certifications: AWS vs Azure vs GCP vs Snowflake
There is no single best data engineering certification — there is a best one for the platform your target employers run. AWS DEA-C01 ($150) is the most broadly requested and the cheapest first exam. GCP Professional Data Engineer ($200) is the hardest on this list and the best paid per holder, but has far fewer job listings. Microsoft DP-700 ($165) is the pick for Fabric and Azure shops, with the only free renewal. SnowPro Core ($175) and Databricks Data Engineer Associate ($200) are specialist picks — narrow, but genuinely differentiating when the job runs on that platform.
And check the exam code before you study anything: Microsoft retired DP-203 in March 2025, Snowflake replaced COF-C02 with COF-C03 in February 2026, and AWS retired the old Data Analytics Specialty in favour of DEA-C01. A surprising share of data-engineering advice online still points at exams that no longer exist.
Data engineering is the rare tech skill where the credential question has a clean answer — because the answer is a platform question, not a prestige question. Nobody hires a "certified data engineer" in the abstract. They hire someone who can build pipelines on the stack they already run: AWS, Azure, GCP, Snowflake, or Databricks. The certification that matters is the one that proves you can do the work on their platform.
So this guide is organized the way the decision actually works: five current exams, compared on cost, difficulty, validity, and renewal — then a decision rule by employer platform. Every figure below was checked against the vendor's own page on November 11, 2026.
The short list
| Credential | Exam | Cost | Format | Valid for | Renewal | Best for |
|---|---|---|---|---|---|---|
| AWS Certified Data Engineer – Associate | DEA-C01 | $150 | 65 questions, 130 min, pass 720/1,000 | 3 years | Re-sit ($150) | Most requested overall |
| Google Cloud Professional Data Engineer | PDE | $200 + tax | 40–50 questions, 2 hours, no published pass mark | 2 years | $100 renewal exam | Highest-paid holders, GCP shops |
| Microsoft Certified: Fabric Data Engineer Associate | DP-700 | $165 | 40–60 questions, 100 min, pass 700/1,000 | 1 year | Free online assessment | Azure and Fabric shops |
| SnowPro Core | COF-C03 | $175 | 100 questions, 115 min, pass 750/1,000 | 2 years | Recert exam or higher cert | Snowflake shops |
| Databricks Certified Data Engineer Associate | DEA | $200 | 45 questions, 90 min, no published pass mark | 2 years | 25-question renewal exam ($200) | Databricks shops |
Prices are US list prices per attempt, before tax. Every retake costs the full exam fee again.
Best overall: AWS Certified Data Engineer – Associate (DEA-C01)
DEA-C01 is the default first pick, and the reason is market share rather than exam quality: AWS runs in more companies than any other cloud, so this is the certification most likely to match a job description you actually read. It launched in March 2024 as the replacement for the retired AWS Data Analytics Specialty, and it is the only associate-level AWS exam built around pipelines — ingestion and transformation (34% of scored content), data store management, data operations, and security and governance.
The numbers, from AWS's own certification page: $150 per attempt, 65 questions (50 scored) in 130 minutes, pass at 720 out of 1,000, delivered at a Pearson VUE test center or online-proctored. No formal prerequisites, but AWS recommends the equivalent of 2–3 years of data engineering experience. Valid for 3 years — the longest validity on this list — and you renew by passing the current version of the exam again. A failed attempt costs another $150 after a 14-day wait.
Realistic prep is 6–8 weeks, roughly 60–80 hours, if you already work with AWS data services (Glue, Lambda, Redshift, S3, Athena), longer if you are learning the services as you go. The exam guide was revised to version 1.1 in December 2025, so use study material written after that date.
Hardest and best paid: Google Cloud Professional Data Engineer
Google's Professional Data Engineer is the only professional-level exam on this list — the rest are associate or foundational — and it shows. Google recommends 3 or more years of industry experience, including at least 1 year designing and managing solutions on Google Cloud, and the exam tests design decisions across BigQuery, Dataflow, Pub/Sub, and Dataproc rather than single-service knowledge. There is no formal prerequisite, but this is not a first-certification exam.
The numbers, from Google Cloud's own certification page: $200 plus tax, 40–50 multiple-choice and multiple-select questions in 2 hours, in English or Japanese, online- or onsite-proctored. Google does not publish a passing score. Valid for 2 years, and renewal is the cheapest of the paid options: a shorter $100 renewal exam (1 hour, 20 questions), or designated Google Skills courses that extend validity by one year.
Realistic prep is 10–12 weeks, roughly 100–150 hours — the heaviest on this list. The payoff, such as it is: salary surveys consistently show GCP data engineers earning slightly more than AWS or Azure peers at the same level (US data-engineer base pay averaged roughly $125,000–$135,000 in early 2026), but there are far fewer GCP roles. This is the pick when your target employers are on BigQuery — and a poor pick when they are not.
Best renewal economics: Microsoft DP-700 (Fabric Data Engineer Associate)
DP-700 is the exam most people mean when they say "Azure data engineer certification" — but note the name change, because it matters. Microsoft retired the old DP-203 Azure Data Engineer Associate exam on March 31, 2025 and rebuilt the track on Microsoft Fabric. DP-700 tests Fabric: lakehouses, OneLake, data pipelines, and real-time intelligence, across three domains weighted roughly equally at 30–35% each. If your study material still says Synapse and Data Lake Storage, it is out of date.
The numbers, from Microsoft Learn: $165 in the US (priced by the country where you sit it), 40–60 questions in 100 minutes, pass at 700 out of 1,000, Pearson VUE test center or online-proctored. No formal prerequisites, but Microsoft expects skill with SQL, PySpark, and KQL — three languages, where the other exams on this list expect one or two. The English exam was updated on October 19, 2026, so again: current material only.
The renewal is the quiet advantage. DP-700 is valid for 1 year, which sounds worse than AWS's 3 years — until you see that renewal is a free, open-book online assessment on Microsoft Learn, taken in the six months before expiry. Held continuously, nine years of DP-700 costs $165 once, against $450 for three AWS re-sits over the same span. Realistic prep is 50–70 hours if you already know SQL and Spark; the KQL component is the part most candidates have to learn from scratch.
Best specialist pick: SnowPro Core (COF-C03)
SnowPro Core is Snowflake's foundational certification, and it is the narrowest credential on this list in a good way: it proves hands-on knowledge of one platform that a large and growing share of data teams run as their warehouse. It is also the exam with the freshest code on this list — Snowflake replaced COF-C02 with COF-C03 on February 16, 2026, and much of the prep material on the internet still targets the retired version. Buy COF-C03 material only.
The numbers, from Snowflake's own certification pages: $175 per attempt ($140 in India, the only regional price Snowflake publishes), 100 questions in 115 minutes, pass at a scaled 750 out of 1,000, delivered by Pearson VUE at a test center or online-proctored. No formal prerequisites; Snowflake recommends 6 or more months of hands-on experience with the platform. Valid for 2 years. There are no free retakes — a failed attempt costs another $175 after a seven-day wait, with at most four attempts in 12 months.
Renewal has more options than the other vendors: pass the abbreviated recertification exam (at a reduced price), pass an equivalent or higher SnowPro certification, or complete a qualifying Snowflake instructor-led course through its Continuing Education program. Realistic prep is 30–50 hours for someone already using Snowflake daily — the lightest exam on this list — and Snowflake University's own free on-demand courses cover most of the syllabus.
Best for the Databricks stack: Databricks Certified Data Engineer Associate
Databricks is the platform exam that has moved fastest from "nice to have" to genuine differentiator: enterprise Databricks adoption has grown sharply, and the exam was refreshed in 2026 (the current guide covers the exam version live as of May 4, 2026, updated August 6, 2026) with new sections on CI/CD and troubleshooting. It tests foundational pipeline work on the Databricks Data Intelligence Platform — Spark SQL and PySpark for ETL, Delta Lake, and workflow orchestration.
The numbers, from Databricks' own exam guide: $200 per attempt plus applicable taxes, 45 multiple-choice questions in 90 minutes, online or at a test center, with no published passing score. Databricks recommends at least 6 months of hands-on use. Valid for 2 years; recertification is by passing the current exam again, or by a shorter 25-question, 60-minute renewal exam — also $200. A failed attempt costs another $200 after a 14-day wait.
Realistic prep is 40–60 hours for someone already writing Spark SQL or PySpark on Databricks. One practical note: every Databricks certification costs $200 and lasts 2 years, so the Data Engineer Professional ($200) is the natural next step after a year or so of the same work — budget the pair, not just the first exam.
What it costs to stay certified
The exam fee is the small number. The number that actually separates these credentials is the cost of keeping one, over the years you hold it:
| Credential | First attempt | First renewal | Cost over ~6 years* |
|---|---|---|---|
| AWS DEA-C01 | $150 | $150 (re-sit) | ~$450 |
| GCP Professional Data Engineer | $200 | $100 (renewal exam) | ~$400 |
| Microsoft DP-700 | $165 | $0 (free assessment) | ~$165 |
| SnowPro Core | $175 | Recert exam, reduced price | ~$500 |
| Databricks DE Associate | $200 | $200 (renewal exam) | ~$600 |
*Assumes you pass first time and renew on schedule at today's prices. Snowflake's recertification exam price is not published as a fixed figure, so the 6-year SnowPro total is approximate.
DP-700 is the cheapest credential to hold long-term by a wide margin — the free annual renewal is worth more than the $15 it saves against AWS on the first attempt. Databricks is the most expensive to hold, because the renewal exam costs the same as the full exam. None of these amounts is large next to a data-engineer salary; the real cost is always the study hours, not the fee.
How to choose: decide by your employer's platform
| If your target employers run… | Start with | Then consider |
|---|---|---|
| AWS (most common) | AWS DEA-C01 ($150) | Databricks Associate, if they also run Databricks |
| Google Cloud / BigQuery | GCP Professional Data Engineer ($200) | AWS DEA-C01, for breadth |
| Azure / Microsoft Fabric | Microsoft DP-700 ($165) | Databricks Associate — Fabric and Databricks often coexist |
| Snowflake as the warehouse | SnowPro Core ($175) | The cloud cert for whichever cloud hosts their Snowflake account |
| Databricks as the platform | Databricks DE Associate ($200) | Databricks DE Professional, after a year of the work |
| No idea yet / switching careers | AWS DEA-C01 ($150) | Revisit once you know the platform — do not collect all five |
One more decision rule, from the demand side: most job ads do not name a certification at all. In an October 2026 count of 21,791 US data-engineer ads, the word "SnowPro" appeared in just 60. Certifications are a filter recruiters use to cut a pile, not a requirement most hiring managers write down. That is why the platform match matters more than the badge — a SnowPro Core on a resume aimed at AWS shops is a line nobody searches for.
What a certificate will not do
No credential on this list gets you hired on its own. Employers hire for pipelines you have actually built and run: the ingestion job that handles bad data without paging you at 3 a.m., the model-serving table that stays fresh, the warehouse that does not cost twice what it should. A certificate is a signal that you did structured study and passed a bar — useful as a tiebreaker, useful for getting past a recruiter screen, useless as a substitute for a portfolio.
So treat the certificate as the structure and the project as the point. Every exam on this list has a free or cheap way to get hands-on — AWS Skill Builder, Google Cloud Skills Boost, Microsoft Learn, Snowflake University, Databricks' free edition — and the work you do there is what you talk about in interviews. The certificate line on your resume opens the conversation. The pipeline is what closes it.

Data engineering certifications FAQ
Which data engineering certification should I get first in 2026?
Start with the certification for the platform your target employers run. AWS DEA-C01 ($150) is the most broadly requested and the cheapest first exam; GCP Professional Data Engineer ($200) is the hardest and best paid per holder but has fewer job listings; Microsoft DP-700 ($165) is the pick for Fabric and Azure shops; SnowPro Core ($175) and Databricks Data Engineer Associate ($200) are the picks when the job runs on Snowflake or Databricks.
Is the Azure DP-203 exam still available?
No. Microsoft retired DP-203, the Azure Data Engineer Associate exam, on March 31, 2025. The replacement is DP-700, Implementing Data Engineering Solutions Using Microsoft Fabric, which costs $165 and is valid for one year with a free annual renewal assessment. Do not buy DP-203 study material.
How long are data engineering certifications valid?
AWS DEA-C01 is valid for 3 years and renews by passing the current exam again ($150). Google Cloud Professional Data Engineer is valid for 2 years, with a shorter $100 renewal exam. SnowPro Core and Databricks Data Engineer Associate are valid for 2 years each. Microsoft DP-700 is valid for 1 year, but renewal is a free online assessment on Microsoft Learn.
Do data engineering certifications get you hired?
No certification guarantees a job. Most US data-engineer job ads do not name any certification — in an October 2026 count of 21,791 ads, "SnowPro" appeared in just 60. A certification helps you pass recruiter screens and signals structured study, but employers hire for pipelines you have actually built and run.
The bottom line
Pick the credential that matches the platform you want to work on, not the one with the best marketing. Most people: AWS DEA-C01 at $150. GCP shops: the Professional Data Engineer at $200, and budget the study time — it is the hardest exam here. Azure and Fabric shops: DP-700 at $165, and enjoy the free renewals. Snowflake or Databricks shops: the platform cert first, the cloud cert second. And before you spend a dollar or an evening, check the exam code on the vendor's own page — in 2026, the exam you studied for may already be retired.
