Abstract : The subjective decisions of a selection-board on accepting or rejecting pilot applicants were subsequently objected by two different methods. In this way the preconditions for applying corrective for mulae were created, enabling the validities of selection tests to be estimated. The validities of the total sample were estimated from the validities of the non-representative sample of the accepted applicants. It was shown that the test-weights implicitly used by the selection-board greatly differed from the optimal weights. The results should be reviewed by way of a cross-validation. (Author)
