This study is a way to figure out the problem and its solution with a compare and contrast in that it is about the connectivity of the performance criterion between achievement standards of machinery filed in vocational high schools and meister high School.

For starters, I choose a Unit about ‘lathe’ in ‘Machine Tool I·II.’ Then, I analyze on learning task: internal cutting, taper cutting, screw cutting, and off-center cutting. By doing so, I develop the achievement standards of the content in that is in accordance with 8 competence unit performance criterion, compared to a study on the link of NCS machinery filed lathe competence.

With this research, I analyze the association based on the criteria for the developed achievement standards and performance criterion: <Repetition>, <Development>, <Gap>. Eventually, I come to a conclusion. Above all, I examine in more detail about content using these 5 categories ? that is, achievement standards and performance criterion: ‘internal manufacture and lathe (simple shape)’, ‘taper cutting and lathe (home & taper)’, ‘screw & off-center cutting and lathe (off-center & screw)’, ‘lathe (task plan)’, and ‘lathe (basic task).’
According to this, it is true that the course content <Repetition> is recycled in subsequent units <Development> on a regular basis. Therefore, it contributes to the spiral learning which leads to a better course. On the basis of NCS, institution of higher education takes a role of organizing the curriculum.
That is because it usually does a course of study intensively rather than high school does. As a result, <Development> is forming an ever-greater part of the course. Still, as for the criterion of ‘lathe (the use of accessory)’, ‘lathe (tool-making)’, and ‘lathe (equipment maintenance and administration), it does not provide enough detail in the course content. The reason why it is inefficient is that the lower content is a shortage of information on <Gap> in order to comprehend a higher content. Especially, <Gap> was higher than <Development> depending upon the criterion of ‘lathe (the use of accessory’) and ‘lathe (tool-making).’

As shown in the study, a practice for ‘lathe accessory’ takes a big part of <Gap>, which is required to include in a high school textbook. What is more, it is necessary that another ‘Tool-making’ is very practical, since students have more opportunity to deal with it in their workplace. I strongly think that we have to introduce them several ways to help such as learning through textbooks or reading materials. Not only that, I believe that current performance criterion of NCS is too broad to use it. Thus, it is asked to set a learning hierarchy for developing the achievement standards. To do this, I recommend that we arrange a unit of competency on the NCS from the lowest-level knowledge to the highest level through the process of conducting a learning task analysis.

All in all, as we can be seen from the research, it is advised to come up with ways to boost the connectivity on NCS and several curriculum for vocational high Schools & meister high schools.
