This article describes the placement testing program, the use of microcomputer software for scoring and analyzing test results, and the integration of the computerized test results into a comprehensive microcomputer-based student information system at the University of California, Irvine (UCI). UCI offers placement tests in five academic fields: chemistry, mathematics, reading, writing, and English as a second language. Test content closely parallels UCI courses. Tests are offered six times a year. UCI academic departments determine the grading criteria for each test, based on performance of prior students and on the availability of courses. Students are notified regarding test results, and copies are sent to academic counselors. The microcomputer-based student information system will contain information on students' use of academic support services, grades, demographic information, and academic background, as well as placement test information. The PAR Testing System, a comprehensive test preparation, analysis and record keeping software program, contains an error log and is menu-driven. Summary information, including means and percentages of students placed in each course, are provided to the academic units. Test statistics, including reliability and item analyses, are sent to the unit which developed the test. Counselors receive listings containing all test scores and the corresponding course placements. (PN)
