Quantitative and qualitative descriptive research. Objective: to validate the survey on the perception of nursing graduates in Chile, regarding the National Exam taken and applied. Methodology: qualitative, using the Delphi method with experts in the areas of nursing, education, and evaluation; and quantitative, using Cronbach's alpha analysis with the SPSS system. Results: The K was between 0.95 to 1, which suggests that all of the experts had a high degree of competence in the opinion topic. The objectives proposed in the 21item survey were linked. In 8 items 100% of the experts stated their agreement with the aspects raised by the National Nursing Exam Commission; in 10 items 80%, in 2 items 50% and in 1 item 33%. Cronbach's alpha method estimated the internal consistency reliability of the instrument to be 0.97, demonstrating a high degree of internal consistency among the items analyzed. Conclusions: to validate an instrument it is necessary to rigorously complete each step with a sequence that allows one to account for validity and reliability.
