In this study, it was aimed at developing an achievement test for 8th grade students about matter cycles and environmental problems. For this purpose, validity and reliability studies were conducted and a test consisting of multiple choice questions was developed. The method of the research was quantitative and the pattern of the research was surveyed. The sample of the study was composed of 251 students from four secondary schools in Malta. Item indices, content, criterion and construct validity studies were conducted within the scope of validity. The construct validity study was performed with exploratory factor analysis using SPSS program. As a result of the reliability study, the KR-20 internal consistency coefficient was calculated as 0.81. In addition, confirmatory factor analysis was performed with LISREL program and the factors determined by exploratory factor analysis were confirmed. As a result of the analyses, a valid and reliable achievement test has been developed. Based on the findings from the validity and reliability studies, suggestions were completed.
