In self-directed e-learning, it is meaningful to diagnose understanding level properly, but it is difficult for the system to do it. Self Organization Map(SOM) is a very useful tool as classifying high dimensional data. This paper presents a new method diagnosing learner's understanding level with SOM. We demonstrated SOM diagnosis experiments for 27 learners. The good results obtained encouraged us to apply the system to self-learning.
