Should you take it?

  • Suits engineers who ship AI agents and want a $99 online-proctored exam split evenly across building, testing, deploying and monitoring.
  • Not for newcomers to agents: a quarter of the exam is testing and another quarter monitoring, skills you learn by doing.
  • It expires after 24 months, and LangChain hasn't said how you renew, so the cost of staying certified is unknown.
  • Take CertNexus's Agentic AI Builder instead if you want an exam that also tests RAG and agent tools, in 25 items.
