The purpose of this study was to determine how large a) Effect of self-concept and mathematics student learning outcome 2) The influence of achievement motivation with students 'mathematics learning outcomes 3) Effect of self-concept and achievement motivation of students' mathematics learning outcomes. The research method used is survey method correlational path analysis (path analysis). The sample populations of this study were drawn from affordable with simple random sampling technique, as many as 232 respondents. Instrument used in this study is a questionnaire instrument; to measure the variable self-concept and achievement motivation, as well as a test instrument to measure the outcome variables studied mathematics. After testing, the third such instrument is valid and reliable, so worthy to be used for further research. Furthermore, the data were analyzed descriptively and performed tests that include requirements analysis test for normality and linearity test so that further analysis using statistical parametric. The calculation result shows that the data is normally distributed, as well as the linearity of regression test showed that the linear regression form. The results of hypothesis testing showed that students' self-concept have a significant relationship with students' mathematics learning outcomes, achievement motivation has a significant relationship with learning outcomes and self-concept and mathematics achievement motivation also had a significant relationship with students' mathematics learning outcomes.
