Note: The new definition is a summation of the contract termination rates by apprenticeship year. The old definition could use this approach only by approximation. Note further, in 2007 the survey method was substantially changed, thereby enabling calculations according to the new definition. Consequently, however, rates before and after 2007 can only be compared with considerable caution.)
