Measure the skills that matter most.

Measure the essential career skills learners need to succeed. Determine the skills you want to measure and assign skill impact scores to responses. Our platform measures individual skill proficiency as a percentile for an objective rating.

The possibilities are endless!

Here are some of the topics our authors have brought to life: Cultural Awareness, Microeconomics, Escape Room, Business Law, Managerial Accounting, Sports Management, Crisis Management, Data Analytics: Forensic Accounting, Ethical Decision-Making, and more!


Foster self-awareness & growth.

Help learners uncover areas of weakness and provide the individualized and actionable feedback needed to grow:

  • Self-assessment – each participant rates their perceived skill levels prior to the simulation experience.
  • Skill-gap analysis – each participant’s self-assessment is compared to their actual performance.
  • Developmental tactics – insights to improve each skill being assessed.
  • Individual development plan – guides participants through the creation of SMART goals and actionable next steps.
