An example of combining laboratory-and field-based study to develop a selection battery for field implementation s described. The procedure provides advantages in comparison with sole use of construct validity data, and fewer field demands for cross-validation. Two experiments were conducted that converge on development of a test battery for selection of air traffic controllers (ATCs). The laboratory study (N=112) used an ATC simulator (terminal radar approach control, or TRACON) for initial development and evaluation of the selection battery. The field study of 206 Federal Aviation Administration ATC trainees provided cross-validation data as a precursor to implementation of the battery. Implications for developing ability-based and self efficacy-based selection measures for complex job performance are discussed, as are general issues for new election research and application.
