Retrieval-Augmented Generation (RAG) Fundamentals Certification

The Retrieval-Augmented Generation (RAG) Fundamentals Certification is a free 20-minute skill test from Science of Apps. It tests how retrieval-augmented generation works — chunking, embeddings, vector and hybrid search, re-ranking, grounding prompts, citations and evaluating retrieval and answers. Score 70% or more on its 20 questions to earn a verifiable Retrieval-Augmented Generation (RAG) Fundamentals certificate (SOA-RAG). Every question is based on published standards and research — including What is retrieval-augmented generation? (IBM), Prompt engineering overview (Anthropic), Machine Learning Crash Course (Google for Developers) — and each answer is explained with its source.

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 Retrieval-Augmented Generation (RAG) Fundamentals 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: What is retrieval-augmented generation? (IBM); Prompt engineering overview (Anthropic); Machine Learning Crash Course (Google for Developers); Prompt Engineering Guide (DAIR.AI); Building effective agents (Anthropic); Define success criteria and build evaluations (Anthropic). 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: Retrieval (Chunking and embeddings, Vector and hybrid search and Re-ranking); Generation and evaluation (Grounded prompts and citations, Retrieval metrics and Answer quality); Indexing and data pipelines (Ingestion and parsing, Metadata and filtering and Freshness and updates); Advanced RAG patterns (Query rewriting, Agentic and multi-step retrieval and GraphRAG and structured data). Every question is an original scenario based on a published standard, official documentation or research, named under the question.

AI engineer, ML engineer, Search engineer, Solutions architect and Data scientist. It suits anyone who wants a quick, verifiable way to show Retrieval-Augmented Generation (RAG) Fundamentals skills, from students and career switchers to experienced professionals.

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 Advanced: assumes years in the role or deep specialist knowledge. 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.

Employers hiring AI engineers in 2027 expect solid retrieval-augmented generation skills: parsing and chunking documents, embeddings, vector and hybrid search, re-ranking, metadata filters, grounded prompts with citations, keeping indexes fresh, and evaluating retrieval and answers separately. Most enterprise AI assistants are RAG systems, so these are core skills. Build a RAG system with a measured retrieval eval and verify your knowledge with a free test.

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.
