e.g. mechanical reasoning, spatial, numerical, motor abilities
For work aptitude tests, how are individuals assessed?
Using the minimum scores necessary for success in a job.
e.g. accounting; one would want high scores in number skills; plumbing, one wants high scores in mechanical skills
Work aptitude batteries are designed to assess what?
A range of basic abilities relevant to many jobs.
- This meant avoiding many different tests for different jobs.*
- Can administer the same measure independent of the occupation because you have a test which covers most things.*
Name 2 examples of aptitude test batteries
GATB; DAT
What do we need to confirm in order to assess the usefulness of ability tests?
Reliability; Test-Retest
Validity; Face Validity, Concurrent validity, Predictive validity
Older ability tests (1920s) were often based only on ____ validity
Face Validity
Reviews of validation studies from the 1950s onwards showed that aptitude tests did _______
No better than IQ
Which kind of jobs are ability tests important for?
Clerical Jobs and physically demanding jobs (e.g. fire fighters, police)
What might you do to test the predictive validity of a ability test?
Have someone take the test before they are employed but don’t look at the results.

A type of selection test that requires the candidate to demonstrate proficiency on tasks representative of the job
- (e.g. driving tests, or using equipment)*
- Another name: Job Replicas*

What are 4 limitations of work samples?
Most ability tests do not assess personality.

- Those with few factors (Eysenck’s Personality Inventory) are limited to jobs requiring broad personality characteristics*
What is The Myers - Briggs Type Indicator (MBTI)?
Can this be used for work selection?
Personality test based on Jung’s theory of personality
