Students in grades 6 to 8 are shown to display considerable variation in test anxiety, and results for this age group are comparable to previous studies with adult populations. Three factors rotated to an oblique solution accounted for 50 percent of the common score variance when a new 31-item version of the Mandler-Sarason Test Anxiety Scale was administered to students. The first two factors, "Worry" and "Emotionality", correspond to those obtained for adults. The third factor, labeled "Concentration", is supported by the attentional theory of test anxiety. Results indicate that the construct of test anxiety can be reliably measured for upper elementary and junior high school students. Tables illustrate the factor correlations with subscale and total test scores, norms and internal consistency estimates and intercorrelations of total test and factor subscales. (Author/CM)
