Using JavaScript to Develop Interactive Self-Assessments 
Interactive self-assessments are effective tools for a variety of audiences; from determining one’s Myers- Briggs Type Indicator (MBTI) or personality characteristics to self-scoring quizzes of all types for online training. Many Web sites contain such selfassessments that help customers select from among other offerings the type of product or service that meets their requirements. The strategic design and development of interactive self-assessments can also help steer customers to your specific product line or service, or even help them make the decision to buy or award a contract. This paper looks at the effectiveness of self-assessments as a business tool and the use of JavaScript for supporting the interactive elements.
