Purpose<br />

ACCELERATED CAT-ASVAB PROJECT<br />

The Accelerated CAT-ASVAB Project (ACAP) is designed to develop and field-test<br />

CAT-ASVAB in the shortest time possible. The idea is to collect “lessons learned”<br />

information about the new test battery, the delivery system (including both<br />

hardware and software), and the testing environment. The information obtained will<br />

be used to specify the functional requirements for the full-scale, operational system.<br />

Delivery System<br />

The Hewlett-Packard Integral Personal Computer (HP-IPC) was selected for the<br />

ACAP System. The HP-IPC is a powerful microcomputer system which, for the<br />

examinee testing station, includes: a Motorola 68000, 16/32 bit microprocessor; a<br />

graphics co-processor; 1.5 megabytes of Random Access Memory (RAM); a built-in,<br />

3.5-inch, 7 10K byte microfloppy disk drive; a g-inch amber, high-contrast<br />

electroluminescent flat screen display, supporting a 255 by 512 pixel, bit-mapped<br />

display, and a standard window size of 24 lines by 80 characters; a go-key, lowprofile,<br />

detachable keyboard (which was modified by a template, leaving only the<br />

necessary keys exposed); and a built-in inkjet printer. The entire computer has a 7<br />

by 16 inch footprint, requiring less than one square foot of desk space. The software,<br />

developed at NPRDC, is written in the C programming language, running under a<br />

UNIX operating system (HP-UX).<br />

Field Research Activities<br />

The Accelerated CAT-ASVAB Project (ACAP) involves six field research<br />

activities:<br />

Pre-Test. The purpose of this research was to insure that examinees could<br />

easily use the CAT-ASVAB System (including hardware and software). <strong>Military</strong><br />

recruits and students from high school special education classes were administered<br />

CAT-ASVAB. In the aggregate, they represented the full range of mental ability.<br />

Results were very encouraging. The examinees found CAT-ASVAB easier and faster<br />

than paper-and-pencil tests that they had taken. They liked the fact that it was selfpaced,<br />

and involved little writing. Some examinees expressed concern that they<br />

could not skip over items, nor go back to previous items and change their answers.<br />

Some examinees indicated that their eyes became tired, which emphasized the<br />

importance of avoiding glare on the screens. Administration instructions were<br />

revised, based upon information from questionnaires and interviews. This revision<br />

reduced the reading grade level from the eighth to the sixth grade. The Pre-Test was<br />

completed in November 1986.<br />

Medium of Administration. The purpose of this research was to evaluate the<br />

effect of the calibration medium of administration on score precision. The subjects<br />

were from the Navy Recruit Training Center in San Diego. Forty-item conventional<br />

tests were constructed for General Science, Arithmetic Reasoning, Word Knowledge,<br />

Shop Information, and Paragraph Comprehension. Subjects were randomly assigned<br />

to one of three groups. The first group took the tests on computer; these data were<br />

used to obtain a computer-based calibration of items. The second group took the same<br />
