So much emphasis and effort is placed upon flashy presentation and delivery, the adventure. Little thought is given to the data collected, or what I see as the treasure. If collected and stored properly, the data gathered by a test management system is a powerful tool that improves learning and outcomes across an organization. Whether you are trying to improve a student’s ability to speak a language, learn a discipline, or if you are trying to find the right employee for your team or certify a candidate's knowledge; the data is critical to your success. Your ability to look at the data collected over the long term is the key to quantitatively improve your outcomes and reach your goals.
