Abstract: This research investigated the effectiveness of the mock-up innovation as instructional material for teaching among the third-year automotive technology students at Bukidnon State University, Malaybalay, Bukidnon, during the first semester of the school year 2018-2019. It highlighted the profile of the students considering: academic status (e.g. regular, irregular); program status (e.g. first course, second course); unit load; family income and size; and major subjects. It also evaluated the pre-test and post-test scores in written and practical examinations on the topics of Test and Repair Wiring/AVR Charging Systems; Test and Repair Wiring/IC Charging Systems; and Servicing Car Batteries, as well as their performance during activities and simulations. External evaluations in written and practical examinations were also done on the 3 topics. Finally, it assessed the effects or influence of all the input and process variables on the output variables of the study with the outcome of a trainer model on a Project Development for the Instructional Trainer Innovation for Automatic Voltage Regulator and Integrated Circuit Charging System. A descriptive research method was used, employing the survey questionnaire and written and practical examinations, to gather the data. Findings revealed the academic and socio-economic profile of the respondents; the results of the pre-and post-test in the written and practical evaluation on the 3 topics where improvements in scores are seen in the post-tests after the utilization of the Trainer Model as instructional materials. However, there were no significant effects of the input variables on the written and practical scores of the respondents.
