The Illinois Inventory of Educational Progress (IIEP) Test Comfort Scale was administered and test results were studied in terms of student achievement and correlates of achievement. Using the revised, seven-item scale, it was determined that: in grade 4, there was no main significant effect for sex or ethnic differences, although Orientals and Whites had more test anxiety than Blacks, Hispanics or American Indians and high achievers in mathematics and reading had higher test comfort than lower achievers. It was also determined that in grade 8: some effect for sex existed; significant ethnic differences occurred, with Orientals showing high test comfort and American Indians high test anxiety. For parental education level and test anxiety of students in grades 8 and 11, it was determined that there was no cross-sex influence and the relationships between test comfort and parental education were generally positive. For eleventh grade students a small but significant sex difference existed, and American Indian and Oriental students manifested the most test anxiety. In all three grades, a positive relationship existed between the number of magazines and newspapers in the home and test comfort. (MH)
