The questions need to be job related.

LyingLying

Applications were compared with factual data.

25% listed previous employers that said they were never employed

25% disagreement on reasons for leaving57% duration of previous employment72% on salary

Misuse and BiasMisuse and Bias

Weighted application blanks - scoring of application blank.

Weight questions related to job successMust insure no weights for age, sex and marital

status.

Ability TestsAbility Tests

Intelligence tests - yield a single intelligence score.

Mental ability tests - multiple scores: verbal work fluency, math, spatial relations.

Relatively high validity

Personality TestsPersonality Tests

Personality - unique characteristics that define an individual.

Personality not clearly related to job performance except for some situations and for some purposes

tests don't identify dimensions important for job performance

Combining MethodsCombining Methods

Multiple hurdle - Each test represents hurdle and if fails any level then don't get job.

Advantage - inexpensiveCompensatory - all tests given to everyone.

Exceptional performance may offset poor performance on another.

Advantage - higher validity.

Summary Summary

The more systematic you can make selection devise the more reliable.
