After analyzing the data by using t-test at the level of significance () 0.05, is got tratio is bigger than ttable, that is tratio = 2.833 > ttable = 1.992, it shows that there is a significant difference between the students’ learning achievement with traditional assessment and portfolio assessment. It can be seen from means of the two classes, mean of the class with portfolio assessment is 70.31 and mean of the class with traditional assessment is 60.00.

This research describes the student’s learning achievement with traditional assessment and portfolio assessment. Based on the result of this research, researcher has the recommendation as follows:
1. In using portfolio assessment, teacher should have well preparation for the materials, assignments, and another activity, which is appropriate with the time allocation.
2. Portfolio assessment is better implemented in small class because teacher will be easier in managing the class.
