This research was conducted to analyze the difference of attitudes and psychomotor of students at the implementation of authentic assessment in PJBL model (treatment group) compared to that at the implementation of inauthentic assessment in PjBL model (control group). This quasi experiment research used pretest-posttest nonequivalent control group design, involving 54 university biology education students in the second semester of 2015/2016. The statistical test used ANCOVA with the significance level of 5% (p < 0.05). The results of this research show that students' attitudes toward Biology material after the implementation of authentic assessment in PjBL model have a difference of 9, 59% higher compared to that after the implementation of inauthentic assessment in PjBL model. The implementation of authentic assessment in PjBl has an effect on students' psychomotor with a difference of 11, 19% higher compared to that at the implementation of inauthentic assessment in the PjBL model. It can be concluded that authentic assessment has a better effect on students' attitudes toward biology material and students' psychomotor compared to those at the implementation of inauthentic assessment in the PjBL model. © 2017 The Journal of Social Sciences Research.
