The basic secondary education in Ukraine covers a period of 5 years past primary
school plus 3 weeks of examinations at the end of the ninth form (last year of studies
in a secondary school). The programme of studies is specified for every academic
year by the Ministry of Education and Science of Ukraine. The pupils' timetable
includes core subjects and optional courses.
In the fifth form all the pupils have the lessons of Ukrainian Language and Literature,
Foreign Language (English, French, German or Spanish), World Literature, Mathe-
matics, Computer Studies, History of Ukraine, Nature Study, Music, Art, Physical
Education, Handicrafts and Health Education. Other subjects are gradually added
on during the next years of studies. For example, World History, Geography and
Biology are introduced in the sixth form; Physics - in the seventh form; Chemistry -
in the eighth form; the Basics of Law - in the ninth. Each subject is taught by a different
teacher. The study load devoted to every discipline varies from one to five lessons a
week. The timetable is different every day. All the lessons are usually attended by the
whole class. Pupils are divided into groups for the lessons of foreign languages, and in
some schools for the lessons of Ukrainian Language. A thematic evaluation in each
subject is made at the end of each thematic unit. It is based on the students' current
performance. The results of the thematic evaluations and final tests are taken into
account when the teacher makes the semester evaluation. At the end of the ninth form
all the students take final examinations. They get the Certificate of Basic Secon-
dary Education at the age of 14 or 15.
This level of education is an important link in the system of education in Ukraine.
