In employment testing, the term “test battery” refers to a group of tests you give job candidates who apply for a particular position at your company.
Your test battery will vary depending on the job requirements, or needs, at your organization.
For instance, if you’re hiring an accountant, you may want to give candidates tests in math and basic accounting, and you might also want to give them a personality profile test to see if they’re detail-oriented, organized, etc. The three tests you administer in this case, then, form a test battery.
Note that you would develop and give a different test battery to someone who applies for a different job, such as in maintenance, engineering, graphic design, etc.
