Only 10% of the newly appointed teachers stay within the system of education, more than half leave after the first year, indicates a World Bank report for the 2014-2018 period. The second year is the most critical with 60% of the teachers leaving after it, and 56% - after the third year.

According to Minister of Education Prof. Nikolay Denkov, 2016 was a year of extremes because of the low teacher salaries. “At the time school headmasters would fire teachers at the end of the school year so as to save money, and re-appoint them in the autumn,” he added. In 2019, 23% of teachers left after their first year, and the explanation lies in the campaign to bring more young people into the education system, as well as the rise in salaries.
