Mathematics plays a significant role in the majority of human activities. It is an instrument of one's everyday life. The main thrust of this study was to determine the Mathematics Performance of the Tagbilaran City College Students, Tagbilaran City, Bohol during the first semester of academic year 2020 – 2021. Mathematics performance was measured based on three aspects: Academic Performance, Mastery Level, and Proficiency Level of students taking up the Business Mathematics subject. This study utilized in depth correlational quantitative research, and documentary analysis. The researcher used purposive random sampling and chose 256 BS Entrepreneurship and BS Office Administration first year students of Tagbilaran City College using researcher-made instruments. Results showed that majority of the students were in the age range 18 – 21 and female. Most of them took BS Office Administration program, were full-time students, and graduated from K – 12 Curriculum. It was revealed that students’ academic performance was Satisfactory. Students proficiency based on the three formative tests taken was at Minimal Level. Seven out of the nine areas in Business Mathematics were not Mastered by the students, within which Depreciation was the least. There is a significant degree of relationship between students’ academic performance in Business Mathematics, and students’ sex, and program, but insignificant to age, type of students, and secondary curriculum taken. There is a significant relationship between the proficiency level and students’ age, program, and type, but found none towards sex, and secondary curriculum taken. There is a significant correlation between Academic Performance and Proficiency Level of the students. There is a significant difference between the academic performance of male and female students but insignificant in terms of Proficiency Level. There is a significant difference on the academic performance, and proficiency level of the students between the two programs. BS Office Administration students overpowered the BS Entrepreneurship students. There is no significant variance between the academic performance and proficiency level of the students at different ages. Significant degree of variance exists on both academic performance, and proficiency level in terms of type of student, and secondary curriculum taken, dominated by Full-time Workers, and Old Curriculum graduates, respectively. There is a significant variance on the Mastery Level in the nine areas of Business Mathematics. The results were the basis in the creation of a Remedial Program for Business Mathematics students in Tagbilaran City College.
