The total instruction days are 200 days(not include the national holidays and the weekend).The term has 20 weeks and each week has 5 instruction days. But it should follow the rule of Personnel Administration Bureau of the Executive Yuan. 2. The learning periods are divided into two categories: the learning periods of the learning fields and the flexible learning periods. 3.

In the principle of having fully instructed the learning periods,the committee of school curriculum development can decide and arrange the learning periods for every learning field in every week. 7. The hours of the tutor , the mid-noon rest and the cleaning activities are not included into the learning periods.The activities of students non-learning periods are arranged by school.
