报告摘要：
With current big data, AI and deep learning uprising, statisticians are at a crossroads whether to make a turn to the fashionable machine learning and deep learning. In Educational Testing, we have been using methods like AI and machine learning for decades. Today we are going to focus on Computerized Adaptive Testing (CAT) and show how it can be utilized to build a tailored assessment for each individual. Our goal is to build many reliable, and also affordable, web-based diagnostic tools for schools to automatically classify students' mastery levels for any given set of cognitive skills that students need to master. In addition, we will show how these tools can be employed to support individualized learning on a mass scale.
