The study aimed to assess the level of acceptability of the mathematics module for non-STEM first-year students enrolled in mathematics programs. The format of the mathematics module contains these essential parts: overview title, learning competencies, and discussion using the 5E's of the Instructional Model: engage, explore, explain, elaborate and evaluate. This mathematics module was implemented to the 79 first-year students as the participants for the evaluation of the acceptability of the said mathematics module. Eight mathematics teachers were included as participants in the evaluation of the acceptability of the module, including the teacher who implemented the module. The mathematics module has excellently met the standards, and no revision is needed, as reflected in the evaluation by the students and the experts. Thus, the developed mathematics module can enhance mathematics competency to minimise the gaps for non-STEM students enrolled in math-related programs.
