Abstract	Electromagnetism is one of the most difficult concepts to grasp in Physics as shown by the decline in the mastery level of grade 10 students in the achievement test administered in school year 2016-2017. To address the problem of declining academic performance in Physics of the students, this study explored the effectiveness of using student-made electric generator as an authentic assessment tool in enhancing retention and understanding of electromagnetism concepts of selected grade 10 students at Malinta National High School in the School year 2017-2018. Utilized the experimental pretest-post test control group design with 45 students who composed the experimental group and another set of 45 students who were assigned in the control group as participants. After the seven-day lecture, the control group was given the usual posttest while the experimental group was asked to make their own electric generator after which they evaluated their outputs using a rubric. Focus group discussion was undertaken by the experimental group wherein their insights and personal evaluation of their experiences while performing the task i.e. making their own electric generator were generated. After one week, both groups were given 30-item multiple choice retention test in order to determine if the use of authentic assessment given to the experimental group promotes better retention than simple lecture and traditional assessment assigned to the control group. Results indicated that the experimental group gained significantly higher mean scores than those of control group in the posttest and in the retention test. It also showed that the experimental group enjoyed the authentic task and captured r\the interest of the students. Based on the foregoing results, the experimental group demonstrated better retention and better understanding of electromagnetism than the control group. The study recommended that teachers should design authentic assessment tools that are relevant and attuned to real-life situations to ensure students’ success in retaining and understanding other concepts in Physics.
