A small-motion test device especially useful as a welding aptitude test and primary training device comprises a target movable along a linear track, and switch means for defining a multi-dimensional envelope of freedom of movement of said target. A wand held by the test subject must affirmatively position the target within the envelope, and maintain it there throughout the time of the test while the target moves along the track at a preprogrammed rate. Success of the test is indicated and accounted for as a function of the percentage of the total test time that the target remains within the test envelope.
