At mid-term of grade six, the registration form for the secondary school will be given to parents together with a primary school report, which include information on skills, accomplishments and inclinations and a recommendation for secondary education.
In the registration form two desired schools can be specified. If the first-choice school does not have enough places, the child will be admitted to the second-choice school. If none of the two wishes can be fulfilled, the child will be assigned to a school at a reasonable distance from the place of residence.
