LangChain certification

LangChain certification is an official assessment program that validates a developer’s ability to design, build, and deploy large-language-model (LLM) applications with the LangChain framework. Candidates study core modules—document loaders, embeddings, vector stores, chains, agents, memory, and observability—and complete hands-on labs such as building a Retrieval-Augmented Generation chatbot and a multi-tool ReAct agent. The exam, delivered online in a proctored environment, mixes multiple-choice questions with a timed coding project graded by automated tests. Passing earns a digital badge hosted on Credly, listing skills in Python, RAG architecture, prompt engineering, and LangChain callbacks. Recertification is required every two years to reflect fast-evolving APIs. Companies use LangChain certification to vet talent for AI roles, while holders gain credibility, community perks, and early access to beta features—turning practical know-how into a recognized professional credential.
