The rule is that 1 class representative and 1 deputy shall be elected per 29th commenced students in the class each academic year. In this relatively short rule, there are some concepts that can be easily misinterpreted, so we'll break it down for safety's sake. This part is most important for the academic staff who will conduct the elections to be well acquainted with.

Choose 1 class representative and 1 deputy

Of course, you want to fill all the vacant roles, but if you can't fill all, you prioritize the main class representatives. If a class is to choose a main and a deputy, but only one student wants to run for the role, you obviously choose for the main role and possibly take the election of the deputy later, if someone should show interest. And in the case where a class is to choose two main and two deputies, but only two students want to run for the role, you choose them both as main, and wait to choose deputies until all main roles are filled.

Per 29th

Here one can easily misinterpret the math, so let's just group who should choose how many. Classes that have 28 or fewer students choose 1 class representative and 1 deputy. Classes between 29 and 47 choose 2 of each, classes between 48 and 76 choose 3 of each, classes between 77 and 105 choose 4 of each, and classes over 106 choose 5 of each.

Commenced student

This concept is here to ensure that a class doesn't suddenly lose class representatives during a school year because someone has dropped out of the study. For example, a class of 29 commenced students should not go from 2 to 1 class representatives if someone discontinues their study before the academic year is over. You calculate how many class representatives a class should have on how many registered students it has at the start of the study, and you make a new calculation only at the start of the study the following year.

Class

For most studies, there is no difference between a class and a cohort, but some studies have so many students in their cohorts that they are distributed over several classes to make it easier to conduct the teaching. And at these studies, it is each class that chooses its own class representatives from the students who are in its class. You also calculate the number of students in the class, not the cohort, when figuring out how many class representatives to choose. For example, in a cohort of 100 students divided into 5 classes of 20 students, you would choose a total of 5 main and 5 deputies, not 4 main and 4 deputies as you would for 1 class of 100.

Each academic year

One must make sure to conduct elections of class representatives for each academic year. This is both so that those who are elected in the first year are not locked into the role for several years, and so that those who find an interest in running afterwards have a new opportunity next year. If the class is not entirely satisfied with the class representative's work throughout the year, this is an undramatic way to give someone else the chance to give it a try. If a class is to continue the educational course after the summer, they can conduct elections of class representatives for the next academic year at the end of the spring semester.
