This desriptive-correlational study aimed to determine the association between in-school training and in-plant internship among technology students of the Western Visayas College of Science and Technology (WVCST) and their respective relationships with the students scholastic performance. Likewise, it sought to ascertain whether or not there are significant differences in the perception of in-school training and of in-plant internship among the student-trainees classified as to gender, major course, type of training firm, and location of internship venue. The dependent variable was scholastic performance; the independent variables were gender, major course, type of training firm and location of internship venue; and the moderator variables were in-school training and in-plant internship. The study employed a researcher-made training rating scale to gather the data from the participants. The student-participants' permanent records in the WVCST registrar's office were used to obtain their GPA's representing scholastic performance. The participants in this research were the 172 technology students selected through proportional random sampling from among the 312 students-trainees who had undergone in-plant internship as of October 1997. Statisitcal tools used were means and standard deviations for descriptive statistics and the t-test, ANOVA and Pearson's r for inferential statistics . Alpha level was set at .05. Generally, both in-school training and in-plant internship were perceived to be very good by the student-trainees. The technology students reflected average scholastic performance. No significant differences existed in perception of in-school training and in-plant internship among the students classified as to gender, type of training firm and location of training venue. However, when classified by course, the Garments and Food students reflected better perception of their in-school training and in-plant internship. Meanwhile, the female students reflected higher scholastic performance than the male students. There was a significant association between in-school training and in-plant internship. However, the students' scholastic performance did not significantly relate with in-school training and in-plant internship.
