Final answer:
Employers need to collect information about candidates' academic and work history, look to trade schools and colleges for pre-screening, and consider signals such as motivation and work ethic.
Step-by-step explanation:
In order for the logic of prediction to work in practice for selecting employees, several factors are necessary. First, employers need to collect information about the candidates' academic and work history as well as any other relevant attributes. This information can include degrees, awards, and references.
Second, employers may use pre-screening methods such as looking to trade schools and colleges for candidates. This helps employers to filter out candidates who have already been evaluated and deemed suitable by reputable institutions.
Lastly, employers rely on signals such as a candidate's motivation, timeliness, ability to get along with others, and work ethic. These signals can be inferred from a candidate's achievements, such as a high grade point average and accolades.
