This subtest measures you ability to mentally rotate blocks in space. In the Block Rotation subtest, you will see blocks of different shapes, with cubes, cylinders, and other objects on them. In the examples below, you see six images. The image in the upper left-hand corner shows the model block. One of the five images labeled A through E also shows the model block, but rotated in space. The remaining images show a different block, rotated to various positions in space. Your task is to choose from the images labeled A through E the image that shows the model block rotated in space.

To show you what a block would look like as it is rotated to different positions, please view this moving image (once image loads, click start or play to begin rotation - 243K). Rotating images will be available during the tutorial only--not during the actual test.

A complete outline of the number of questions per sub-test and the maximum time allowed for each tutorial and sub-test is available.
