The purpose of this work is 9. It is to develop a valid and reliable success test for the class "Nature and Chemistry" unit. For this purpose, the results of the 2018 Secondary Education Chemistry Course Teaching Program and the curriculum books were first examined and 53 questions were prepared taking into account these achievements. After the content of the questions created was checked by 2 faculty members, the test was studied by 2 chemistry teachers to ensure the validity of the scope. The number of questions has been reduced to 29. Pilot application, a total of 181 (89 girls, 92 men) who studied in 3 different high schools. It was performed with the student. This application was eventually calculated as Cronbach Alpha 0.889 and decided to remove 4 issues from the test. The final "Nature and Chemistry Unit Success Test", 10. 421 students were appointed. The Cronbach Alpha value of the test was re-calculated and determined as 0.886. The analysis of the factor determined that the test consisted of 4 factors and the Cronbach Alpha values for each factor were between 0.61 and 0.76.
