This study aimed to analyze the productive disposition and its correlation with mathematics achievement of Islamic Junior High School students. A total of 149 Islamic Junior High School students in Jombang was procured as samples. Statistical analysis was based on the Spearman rank correlation and on the ttest. The findings showed that at average, the productive disposition of the Islamic Junior High School students were categorizing low. Furthermore, there was a positive and significant correlation between the productive disposition and mathematics achievement of the Islamic Junior High School students, though the correlation coefficient was not high. An observation was also made to analyze this correlation, and it was found that though some students have good the productive disposition, sometimes they could not do the tests well, because of the condensed curriculum, and also their social activities, which make their mathematics achievement become lower.
