computer-based administration, students' only interaction with an adult occurred when they were led from their classroom to the school library, where each student was seated at a table with the Apple II computer. They were informed that the computer would administer the directions and that they could press the space bar on the computer keyboard to repeat any instructions or words if needed. The PPVT-R software program verbally delivered the test instructions and presented the visual sample test items. After each student met the standard for administering the PPVT-R, the software program followed the PPVT-R standard test instructions, verbally presenting the stimulus word while displaying the visual choices. The software administration also included offering verbal praise to the child for correct responses when appropriate and informing each student when the test was completed.

Due to known validity and reliability coefficients of the PPVT since the early 1970s, the PPVT provided an instrument against which questions related to mechanized testing systems could be studied. Mechanized testing systems were testing systems which integrated equipment such as slide projectors and
