# Overview The final stage of the certification process takes the form of a take-home exam, where you will perform an analysis and present the results. The skills that we are testing depend on the certification. ### Data Scientist We will be assessing your skills in model development and communication. We want to see that you can take a business problem, select and implement appropriate techniques and then give a relevant summary of what you have found to the defined audience. You will need to write a technical report and give a presentation aimed at a non-technical audience. You can find information on how we grade your Data Science case study in the full [rubric](https://s3.amazonaws.com/talent-assets.datacamp.com/Case+Study+-+General+Info.pdf). ### Data Analyst We will be assessing your skills in visualization and reporting.
