The study assessed the mathematics performance and self-efficacy of Grade 9 students
at Central Mindanao University Laboratory High School (CMULHS) in a Differentiated
Assessment (DA). It aimed to a) determine the mathematics performance of students exposed to
DA and those exposed to non-DA in terms of pretest, posttest, and retention test; b) ascertain the
self-efficacy of the students towards Mathematics exposed to DA and those exposed to non-DA;
c) differentiate the mathematics performance of students exposed to DA and those exposed to
non-DA in terms of post-test, and retention test; and d) compare the self-efficacy of the students
towards Mathematics exposed to DA and those exposed to non-DA. This study used the quasiexperimental
research design. The mathematics performance of the students in the pretest,
posttest and retention test when exposed to DA and non-DA varies from very low to high. The
self-efficacy level of the students varies from moderately low to moderately high. There was a
highly significant difference in the post-test and retention scores of those students exposed to DA
compared to those exposed to non-DA. Moreover, the DA group had a significantly higher selfefficacy
level towards Mathematics compared to the non-DA group.
