This research aims to analyze and implement a distribution model obtained from grade result data of students of Mathematic Education Program so as to present the most useful information while their achievements are one factor of education quality control. For these reasons, this research investigates students' achievement. The data are gained from their results of final semester exams on several subjects for the past three years. The analysis is conducted by clustering the subjects completed by the students. One of continual distribution used is Weibull distribution. The distribution attained is estimated by the Maximum Likelihood Estimation (MLE) method using Newton Raphson iteration. This research is supposed to deepen the statistical concept and numerical method particularly Weibull distribution using Maximum Likelihood Estimation along with Newton Raphson iteration and their application as well as to provide the Study program of Mathematic Education with problem solving alternatives and information to enhance learning quality in order to control the progress of students' achievement on subjects learned and motivate them.
