Virginia Highlands Community College (VHCC) implemented MTH 155 -- Statistical Reasoning Co-Requisite -- in the spring semester of 2018. MTH 155 replaced MTH 146 on VHCC's campus. Prerequisites for this course are the first five developmental MTE modules. The intended co-requisite audience for this new course consists of students having successfully completed at least three of the five MTE modules. These students co-enrolled in MCR 5 and received targeted assistance for the MTH 155 course. Successful completion of MTH 155 resulted in the prerequisite MTE modules 1-5 being satisfied. This paper will present the results of this study along with implications for future work with co-requisite mathematics courses.
