Classes are reshaped at the end of the 4th grade, often based on academic performances. Many schools have special classes (such as intensive English classes or Informatics classes, providing one or two more courses in these subjects). Selection for such classes is done based on local tests. Assessing the students' performance is also different between primary and gymnasium cycles. Starting with the 5th grade, students have a different teacher ("profesor") for each subject. Furthermore, each class has a teacher designated to be class principal ("diriginte"), besides teaching his or hers usual subject. Additional counseling may be provided by a special counselor ("consilier pe probleme de educație" – counselor on educational issues) or by a school psychologist.
