Technical Characteristics and Some Correlates of the California Critical Thinking Skills Test, Forms A and B. AIR 1994 Annual Forum Paper.
Jacobs, Stanley S.
This study analyzed and tested the equivalence of Forms A and B of the California Critical Thinking Skills Test (CCTST). In designing the CCTST, Form A was composed of 34 items from a bank of 200. To develop a parallel measure, Form B was developed by rewriting 28 of the 34 items and rearranging their order. Study participants were all entering first-year students at a large private university. During other orientation activities 684 students completed Form A and 692 students completed Form B. Results of data comparison found that arithmetic means for the forms were significantly different indicating a lack of equivalence between forms. Principal component analysis and specific patterns of item intercorrelations differed between forms, with the lack of equivalence apparently due to the changes in Form A items which were carried out in order to create Form B items. Internal consistency reliabilities for total sub-test scores were uniformly low, and it appeared the CCTST scores largely reflect verbal intelligence of the type measured by the Student Aptitude Test (SAT). Analysis of the results concluded that CCTST may be acceptable for research purposes but not for decision-making concerning individual students, especially with respect to sub-test scores and score differences.
