This overview evaluates the effectiveness of an alternative interactive scenario based assessment system (ISBAS). ISBAS addresses the limitations of traditional assessment methods, allowing students to troubleshoot complex scenarios, ask questions, and make diagnoses through an interactive web interface. The choices the student makes are tracked and scored based on predetermined, objective values. An analysis of student choices/decisions is used to assign a grade/proficiency level and provide the student feedback. ISBAS is efficient, flexible, and objectively evaluates the sophistication of complex knowledge and skills. The research question: is ISBAS more effective in assessing complex knowledge and skills in students than traditional methods of school assessment? This is a complex question; this study is a continuing step in the research to answer it.
