Comparing DiSC® to MBTI®?
With the release of Everything DiSC® Workplace® and the Everything DiSC Comparison Report, there are more reasons than ever for people to compare the two best known assessments for training.
People who know MBTI and DiSC agree that they both are valuable learning tools. But to select the best tool for the job, you need a clear understanding of the organisation’s goals.

People prefer DiSC when:

  • Their goal is to get people to work more effectively together

Do you have a team, group, or even a whole organisation that you need to help work more effectively together? Everything DiSC Workplace gives everyone a common language that helps them build more effective working relationships — one relationship at a time.

  • Training time is limited

Do you need something that participants understand quickly and can apply right away? DiSC has always been an intuitive and useful model that people can get their heads around — fast. Everything DiSC Workplace and the new circumplex model make it easier than ever to use and apply DiSC.

  • They want follow-up to ensure the training gets used

Follow-up makes training stick. And no one can afford training that doesn’t stick. That’s why Everything DiSC Workplace comes with unlimited access to the Everything DiSC Comparison Reports — the most powerful follow-up tool available.
