The purpose of this study was to look at the construct validity of the Critical Thinking Disposition (CTD) Test in Biology. Referring to Facione theory, there are seven indicators of CTD: truth-seeking, open mind, analyticity, systematicity, self-confidence, inquisitiveness, and maturity. The instrument used is ten groups of questions consisting of 7 questions that lead to the CTD. The test is presented in the form of cases relating to biological content and have been validated by experts. The study involved 526 respondents who are biology education students from two universities in Bengkulu with study level (year1, 2, 3 and 4). After confirming with CFA, the results show that the CTD test has suitable construct validity. This result is supported by the value received from Convergent Validity which includes the factor loading value of more than 0.5, while the Composite Reliability (CR) and Average Variance Extract (AVE) values for seven indicators of CTD are truth-seeking (CR=0.96, AVE=0.72), open mind (CR=0.94, AVE=0.61), analyticity (CR=0.97, AVE=0.76), systematicity (CR=0.96, AVE=0.69), self confidence (CR=0.98, AVE=0.83), inquisitiveness (CR=0.93, AVE=0.56) and maturity (CR=0.97, AVE=0.75). From the results can be concluded that the test has construct validity and high composite reliability to measure the CTD in biology.
