Understanding the students` ability and tendency of self assessment is one of the important factors in helping their learning and in giving the appropriate feedbacks. The purposes of this study is to analyse the coincidency of the students` self-assessment with the teacher assessment, and the tendency of over and under estimation. The students performed open investigations and assessed their process skills by checking their investigation reports with a given checklist. The total mean of the `Self-Assessment Capability(SAC)` was 0.73 by 1. The SAC was related to the achievement, not to the gender. The correlation between SAC and achievement was significantly positive(r=0.7, p<.01), and for the girls, the tendency was remarkable. Among the five areas of process skills of open investigation, students got the highest SAC score in the managing and interpreting data area, and the lowest SAC in the drawing conclusion area. The mean of `Self-Assessment Tendency(SAT)` for all items showed that students overestimated their process skills. While the high achievement students underestimated their process skills, the middle and low showed the tendency of overestimation.
