A screening system usually serves to eliminate applicants who do not meet the minimum qualifications specified by the carrier and normally precedes the selection system. An applicant must complete the screening process successfully before beginning the selection process. For example, assume an air carrier indicates that an applicant must have 1200 total hours to be considered. Despite this specification, some pilots with less than 1200 hours apply. The screening system identifies these individuals immediately and eliminates them from further consideration.
