A test tray for a handler for testing semiconductor devices is disclosed which is capable of reducing the costs and time taken for replacement of carrier modules, and achieving an enhancement in workability. The test tray includes a frame, pockets mounted to the frame while being uniformly spaced apart from one another, each of the pockets including a seat on which a semiconductor device is to be seated, latches mounted to the frame to be arranged in pairs for respective pockets such that the latches of each latch pair face each other at opposite sides of an associated one of the pockets, respectively, each of the latches being movable between a first position where the latch holds a semiconductor device seated in the seat of the associated pocket and a second position where the latch releases the held state of the semiconductor device, and latch operating members each mounted to the frame, and adapted to move an associated one of the latches between the first position and the second position, each of the latch operating members being separate from the associated latch.
