Assessments are simply tools. If you've ever tried to fix something you didn't have the right tool for, you can appreciate the feeling of having the right tool for your projects and problems at hand.

Is it accurate?
How will I apply?
Like many tools, assessments are NOT created equally. Inaccuracy can give you false confidence and eventually blow up in your face.
The most important rule of assessment use: Ask questions until YOU are confident in the predictability! (FAQs)
