About this Category


Since 2020, the Department of Census and Statistics has been implementing new and innovative strategies to better engage with the general public through better visual design, a consistent organisational image and advanced data visualisation techniques. This new training course intends to familiarise DCS staff members with principles of design and data visualisation.


This is a two tiered course, delivered primarily through DCS’s VLE, with tier one comprising of design and brand image, and design two comprising of data visualisation and data driven design; both tiers are intended to provide the staff with a multidisciplinary skillset to better communicate with data users.

For whom?

While the course is open to all DCS staff, staff members with previous experience in desktop publishing and graphic design and/or basics of programming will benefit the most. Computer literacy and a good working knowledge of English is a must, since the course will be delivered primarily in English.

How long?

The approximate course delivery period is 3-4 weeks, with 2 weeks of in person sessions, and 2 weeks of self study and assignments. Tier 1 and Tier 2 can be completed separately, or the attendee may chose to take either Tier 1 or Tier 2 only, depending on their preference/ skill level. A certificate will be offered for both levels and an additional certificate of accomplishment to those who finish both.

How much effort?

The course involves practical exercises as well as online questionnaires, and attendees are expected to self study and research topics in their own time to get a better grasp of the concepts discussed in the study guide.


Courses will start towards the end of the 1st week of September, 2022- exact dates are subject to announcement.
