Employers that use general tests to screen applicants run the risk of facing a disparate-impact discrimination lawsuit. If that happens, you will have to prove that the test measures qualities that relate to actual job duties.
Recent case: New York City’s Board of Education required all applicants for teaching positions to pass a qualifying examination called the Liberal Arts and Sciences Test (LAST) before being hired.
A group of black and Hispanic applicants who failed sued, alleging that the test had a disparate impact on them.
The board argued that the test was developed to assess general liberal arts and science knowledge. But it did not investigate the job tasks that a teacher must perform to do the job, and instead used liberal arts curriculum documents to construct the test. The court said that wasn’t good enough.
