Through a series of questions on a range of topics, we are able to establish that this individual has the knowledge required for a data analyst role. We make use of adaptive testing approaches to understand to a high degree of confidence the skill level of individuals who take the assessments.

Practical exam submission

This stage of the certification is graded manually and stringently by our data experts. The candidate must complete a written report that addresses a business problem. In this report, they’ve selected appropriate visualizations, fitted and evaluated a model, and effectively defended their decisions.
