The purpose of this study was to diagnose, using the Newman error analysis model. The error committed when students solve quadratic equation using completing square method. The target population was all SS3 students in Nasarawa State public schools. Three research questions and three hypotheses were answered and tested respectively. Survey design was used for the study. Data collected was analysed using student t-test. The result of the findings showed that all the students committed errors at various stages of Newman model and there is no significance difference in the means of errors committed by SS3 students that solved quadratic equation using completing square method.
