A project was undertaken to develop and implement domain-referenced tests (DRTs) for welders' helpers. After analyzing the results of a state survey of welding job titles and related tasks and after consulting with postsecondary educators and industry personnel, researchers developed DRTs to measure various tasks typically performed by welders. Included among the content areas covered in the tests were edge, butt, lap, tee, and corner joints; plug holes; carbon steel; work orders; power sources; controls; cables; properties of shielding gases; types of shielding gases and mixtures; wire electrodes; protective equipment; cleaning surfaces for welding; starting arcs; restarting arcs; cleaning welds; weld troubleshooting; testing welds; and removing weld defects. Because of time constraints, researchers were unable to field test the examinations. However, the DRTs were used as final performance tests at the end of the school year. Students using the DRTs did well on them. In addition, some students reported that they enjoyed using this type of test. Recommendations called for fully explaining the nature of the tests to those students who will be using them and for using the DRT format more frequently throughout the school year.
