A test handler includes a loading unit for loading semiconductor devices from customer trays onto a test tray; a test chamber for performing a test for the semiconductor devices loaded on the test tray; a pushing unit having at least one pushing member for pushing the test tray located in the test chamber to be tested, and a press unit for operating the pushing member; a position control unit for adjusting a position of the pushing member to compensate a deviation between the pushing member and the test tray due to a thermal expansion or contraction of any one of the pushing member and the test tray; and an unloading unit for unloading the semiconductor devices loaded on the test tray onto the customer trays after a test for the semiconductor devices is completed.
