Hi Alejandro,
You can find out general information about the National Instruments certified programmer exam by visiting http://www.ni.com/custed/nicp.htm. The certified programmer exam for LabVIEW consists of two parts. The first part contains multiple choice questions pertaining to LabVIEW programming and the LabVIEW environment. The second part contains application development questions, where with each question you are given a task with specified parameters, and you develop VIs that satisfy the requirements of the question.
Best regards,
