The Selection Task Force (STF) of the EATCHIP Human Resources Team (HRT) has produced guidelines for the establishment and application of procedures and tests for the selection of air traffic controller candidates (ab initio trainee controllers) in ECAC States. The guidelines describe the methods used and the results obtained by the STF. The guidance material includes recommendations regarding the strategic and tactical aspects of implementing selection activities (procedures and tests) and the use of 'Best practices' in selection activities. The total selection process was examined. As far as possible recommendations are related to common practice as identified in a survey of ECAC States undertaken by the STF.
