Data for Leaders Proficiency

  • 25m
  • 25 questions
The Data for Leaders Proficiency benchmark will measure whether a learner has had significant exposure and experience with data technologies. You will be evaluated on your ability to recognize the concepts of data such as big data analytics, data architecture, data processing, data governance and management, and emerging new age architecture. A learner who scores high on this benchmark demonstrates independent knowledge across a variety of data technologies and platforms.
