Education in Ukraine

Ukraine produces the fourth largest number of academic graduates in
Europe. There is nearly 100% literacy in Ukraine.11 years of schooling is mandatory.
As a rule schooling begins at the age of 6. The Ukrainian education system is
organised into five levels: preschool, primary, secondary, higher and postgraduate
education. Schools receive 50% of their funding from the city budget and 50%
from the national Government budget.
Primary and secondary education is divided into “younger”, “middle”
and “senior” schools. The objective of general schooling is to give younger students
knowledge of the arts and sciences, and teach them how to use it practically.
The middle school curriculum includes classes in the Ukrainian language,
Ukrainian literature, a foreign language, world literature, History of Ukraine, world
history, geography, algebra, geometry, biology, chemistry, physics, physical
education, music and art. At some schools students also take environment and
civics classes. Potential graduates are scheduled to undergo external independent
testing after the final state examination, in the following subjects: Ukrainian language
and literature, history of Ukraine, mathematics, biology, physics, chemistry,
geography and a foreign language. The results of the testing have the same
status as entrance examinations to institutions of higher education.
Higher education is either state funded or private. Students studying at state
expense receive a standard scholarship if their average marks at the end-of-
term exams and tests are at least 4 (according to the 5-point grade system).There are
two degrees conferred by Ukrainian universities: Bachelor’s Degree (4 years)
and Master’s Degree (5-6th year). Upon obtaining a Master’s degree a student
may enter a university or a scientific institute to pursue post-graduate
education. The first level of postgraduate education results in the Candidate
of Sciences. Candidates must pass three qualifying exams (in the field of
specialty, a foreign language and in Philosophy), publish at least three
scientific articles, write a dissertation and defend it. This Degree is roughly
equivalent to the Ph.D. in the United States. After graduation a student
may continue postgraduate education for a Doctor of Sciences Degree.
