CPES validates the foundations of generative AI and effective prompting for practical AI-assisted work. This entry-level OpenEDG credential confirms the ability to design, test, evaluate, and refine prompts. There are no formal prerequisites. The 40-item English exam lasts 80 minutes plus a short tutorial, and candidates need a cumulative average of at least 70% to pass. Exam CPES-520-0x.
Explain how generative AI produces responses and where its limitations lieChoose appropriate AI capabilities and tools with model constraints in mindGive prompts a clear task, intended outcome, audience, and use caseProvide relevant context and input data and handle ambiguous or missing informationApply constraints and control tone, style, level of detail, and output formatDefine success criteria, organize instructions with roles and examples, and create reusable prompt templatesManage conversational context and refine outputs with follow-up promptsBreak complex tasks into steps through prompt chainingGround AI responses in supplied sources and set evidence and traceability requirementsDesign prompts for summarization, extraction, classification, ideation, analysis, and planningDesign prompts for image generation and work with multimodal inputsEvaluate outputs against requirements and verify factual, numerical, and source-based claimsDiagnose weak outputs and refine, compare, and test prompt variants across edge casesProtect sensitive information and recognize security risks from untrusted inputsReduce harmful or biased outputs and address legal, IP, and disclosure considerations with human oversight
