"IN PROHIBITING DISCRIMINATION ON THE BASIS OF RACE, COLOR, RELIGION, SEX, OR NATIONAL ORIGIN, THE ACT SETS FORTH A NUMBER OF EMPLOYER ACTIONS, THE COMMISSION OF WHICH CONSTITUTES UNLAWFUL EMPLOYMENT PRACTICES . . . ." THE TOWER AMENDMENT TO THE ACT SAYS IN PART "IT SHALL NOT BE . . . AN UNLAWFUL EMPLOYMENT PRACTICE FOR AN EMPLOYER TO GIVE AND TO ACT UPON THE RESULTS OF ANY PROFESSIONALLY DEVELOPED ABILITY TEST, PROVIDED THAT SUCH TEST, ITS ADMINISTRATION OR ACTION UPON THE RESULTS IS NOT DESIGNED, INTENDED OR USED TO DISCRIMINATE BECAUSE OF RACE, COLOR, RELIGION, SEX, OR NATIONAL ORIGIN." THE IMPLICATIONS OF THE ACT, AND PARTICULARLY OF THE TOWER AMENDMENT, ARE DISCUSSED, AS IS POSSIBLE COURT INTERPRETATION. QUESTIONS CONCERNING THE NATURE OF ABILITY TESTS ARE CONSIDERED. PSYCHOLOGISTS HAVE RESPONSIBILITIES FOR EDUCATION, RESEARCH, SOUND PROFESSIONAL CONDUCT, ETHICAL ACTION, AND TO RECOGNIZE THE LIMITATIONS OF TESTING. (20 REF.)
