Assessment is based on the following data: • Annual turnover in senior civil service positions during the year in which the government was last formed (calculated as the number of civil servants who left their position, divided by the total employment in those positions at the beginning of the year, expressed as a percentage); • Annual turnover in senior civil service positions during the year after the latest formation of the government (calculated as the number of civil servants who left their position, divided by the total employment in those positions at the beginning of the year, expressed as a percentage); • Annual turnover in senior civil service positions during the latest full calendar year (calculated as the number of civil servants who left their position, divided by the total employment in those positions at the beginning of the year, expressed as a percentage); • Turnover in senior civil service positions within six months from the date of the formation of the current government (calculated as the number of civil servants who left their position, divided by the total employment in those positions at the day preceding the formation of the current government). For the calculation of the sub-indicator the highest value of the four mentioned above is taken. Data relates to central government administration only.
