This study aims to develop a valid and reliable test to measure the conceptual knowledge of secondary school students about geoscience subjects in science education. Before the test questions were prepared, the learning outcome lists were created, and it was seen that the learning outcome lists in the MEB science curriculum were limited (insufficient). For this reason, the list of learning outcomes has been expanded by taking into account the geoscience achievements of the countries that have been successful in international exams and have access to science education programs. In order to ensure harmony between the questions in the test and the learning outcome lists, a table of specifications was created and the opinions of teachers and field experts were consulted. The pilot study of the test was conducted with 48 students and the test was finalized. The Geoscience Achievement Test was administered to 187 seventh-grade students. The KR20 reliability coefficient of the test results was found to be .810. With the item analysis, the mean item difficulty and discrimination indexes of the test were calculated as 0.556 and 0.411, respectively. These results show that valid and reliable results were obtained with the developed Geoscience Achievement Test. It is aimed that the developed test will contribute to the field of science education and be used in future research on the subject. It is believed that with this test, teachers will have the opportunity to measure the knowledge levels of their students on the acquisitions of geoscience subjects and to organize learning activities accordingly.
