There is not a minimum score required for the Mechanical Reasoning Test in order to be admitted into the Diesel Technology program. I'm including the link to the Testing Center website for your review. On the right side of the page, you will select the campus location to get testing center hours and contact information for the campus of interest. Not all campuses offer the Mechanical Reasoning Test. https://www.dmacc.edu/testingcenter/Pages/welcome.aspx
