The results of the research on vocational training in corn processing with an apprenticeship pattern approach showed an effective and efficient way to increase the competency of participants, with the following details: (1). The organizing aspect shows that the 21 elements that are assessed show that they are in accordance with ISO 9001: 2015 targets. (2.)

The aspect of correlation between participant education and the increase in scores between pre-test and final score (a combination of post-test scores and performance scores). From the results of the correlation between the education of participants with an increase in value it is obtained that the highest average increase in value (42.00) is obtained by participants who have D3 education, while the average increase in the lowest value (25.00) is obtained by participants who have S2 education (8). Correlation Aspect between participant's home district with an increase in value between pre-test and post-test. From the results of the correlation between the districts of origin of participants with an increase in value obtained that the average highest increase in value (64.00) obtained by participants who came from Karangasem Regency, while the average lowest increase in value (10.00) was obtained by participants who came from Tabanan Regency . The results of the analysis of the various aspects above analyzed in the training show the success of the activities compared to ISO 9001: 2015 quality targets
