A test tray includes a rectangular shaped frame and a plurality of transport modules to receive a plurality of semiconductor devices. A precise location-determining unit mounted on both sides of the frame to precisely determines and fixes the test tray location. According to one embodiments, the precise location-determining unit includes a locking hole to receive a positioner, a bushing to prevent locking hole wear, a protection bar to cover the frame and the bushing. The test tray prevents yield reduction and handler malfunction, e.g., sudden stopping of the handler, by precisely fixing tray and semiconductor device position during loading, unloading, and testing. The test tray can be extensively without repair or replacement because locking hole, with protective bushing therein, enjoys little or no wear.
