Certified Professional Data Scientist (CPDS)

A professional certification in data science is a signal to employers that you have the capability to operate at a high level within a professional context.

Why become a Certified Professional Data Scientist?

Employers increasingly look for data scientists with both academic backgrounds and industry recognised professional credentials that demonstrate practical, specialised industry knowledge. A recent study from Elucian found that over 85% of employers will expect employees to have professional credentials in addition to a degree qualification. 

The CPDS exam is designed for practising data science professionals with a relevant postgraduate qualification or equivalent from a recognised university, higher education institution or awarding body, together with a minimum of two years’ professional experience in data science.

The Certified Professional Data Scientist (CPDS) exam tests the key knowledge and skills required for the Data Science professional. It demonstrates to employers that holders of this credential are competent at a high level in statistics and maths for data science, programming skills, predictive modelling, machine learning and working with both structured and unstructured data. In addition a CPDS has a proven minimum professional experience and academic education.

How the certification works?

In order to achieve the CPDS must submit copies of academic qualifications from a recognised institution together with evidence of relevant professional experience and success in the CPDS professional exam.
