Apache Airflow Certification

The Apache Airflow Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests Apache Airflow skills for Airflow 3 — DAG and task fundamentals, scheduling, data intervals and assets, DAG authoring with the TaskFlow API, operators, sensors and dynamic tasks, and running Airflow in production with executors, connections, retries and best practices — written to the Apache Airflow documentation, the Airflow 3 release notes and Astronomer certification topics for 2026. Score 70% or more on its 20 questions to earn a verifiable Apache Airflow Proficiency certificate (SOA-AA2). Every question is based on published standards and research — including Apache Airflow documentation (Apache Software Foundation), Apache Airflow best practices (Apache Software Foundation), Apache Airflow release notes (Airflow 3.x changes) (Apache Software Foundation) — and each answer is explained with its source.

Science of Apps offers a free Apache Airflow Certification, updated for 2026 and 2027. It measures DAG and task fundamentals, scheduling, data intervals and assets, DAG authoring and running airflow in production and gives instant results with a shareable certificate.

Read the four skill areas on this page, then take the 20-minute test online — no fee, course or sign-up. You see every answer explained when you finish. Score 70% or more and you get a Apache Airflow Proficiency certificate straight away, on screen, as a PDF and by email, with a credential ID anyone can verify.

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: Apache Airflow documentation (Apache Software Foundation); Apache Airflow best practices (Apache Software Foundation); Apache Airflow release notes (Airflow 3.x changes) (Apache Software Foundation). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: DAG and Task Fundamentals (DAGs and tasks, Dependencies and Task states); Scheduling, Data Intervals and Assets (Schedules and cron, Data intervals and catchup and Assets); DAG Authoring (TaskFlow API, Operators and sensors and XComs and dynamic tasks); Running Airflow in Production (Executors, Connections, variables and secrets and Reliability and best practice). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Data engineer, Analytics or ML engineer, Platform or DataOps engineer, Backend developer automating workflows and Data team lead. It suits anyone who wants a quick, verifiable way to show Apache Airflow knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

The Apache Software Foundation does not certify Airflow skills, but Astronomer offers widely used free certifications — Airflow Fundamentals and DAG Authoring — through Astronomer Academy. This practice test covers the same core topics for Airflow 3.

Airflow 3 introduced a new React UI, DAG versioning, a Task SDK and task execution API, assets (formerly datasets) for data-aware scheduling, and scheduler-managed backfills. It also removed legacy features such as SubDAGs and SLAs, and new DAGs no longer catch up on missed intervals by default.

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.

20 questions — 5 from each of 4 skill areas — with a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

We rate it Intermediate: assumes hands-on experience in the role. It has 20 scenario questions — 5 from each of 4 skill areas — and a 20-minute limit. You need 70% (14 of 20) to pass and 90% for distinction.

Nothing. There is no fee to take a test, to receive the certificate, to have it emailed or to verify it, and no sign-up.

On our server, not in your browser. The answers never reach the page until you submit, so a certificate can only be earned by passing. Each certificate gets a unique credential ID stored by Science of Apps.

You see your score for each area and every question with the correct answer and why, with the published source behind it. You can retake after 30 minutes, and the retake draws questions you haven't seen yet.

No. Every certificate is dated, so it always shows when you passed. Retake a test any time for a newer date or a higher score.

Yes. After you pass, Add to LinkedIn opens the Licenses & certifications form with the certificate name, Science of Apps as the issuer, the issue date, your credential ID and the verification link filled in. You can also download it as a PDF or PNG, and it's emailed to you as a PDF.

Every certificate has a credential ID and a QR code. Scanning it, or entering the ID at scienceofapps.com/certification/verify/, shows the holder's name, the certification, the score and the issue date from our records.

No. They are Science of Apps' own assessments of applied skill. They aren't issued by a university or standards body, and they work best alongside a portfolio that shows the skills in real work.
