This study aimed to develop a two-tier multiple choice test about the concept of “light and optical instruments” in the 8th grade of the Indonesian science curriculum. The test development procedure had three general steps: (1) defining the content area of the test; (2) identification on students’ conceptions; and (3) developing the two-tier multiple choice test. The final version of two-tier multiple choice test consisted of 25 items question. This test was administered to 95 junior high school students. The students had completed a unit on light and optical instruments. The reliability of the test was 0.76. Based on the data analysis, twenty-two alternative conceptions were identified. The results of the study showed that the two-tier multiple choice test was effective in determining the students’ misconceptions and also it might be used as an alternative to the traditional multiple choice test. In conclusion, two-tier multiple choice test could be used to assess students’ conceptual understanding as well as students’ misconceptions on light and optical instruments concept. © 2018 Science Education Study Program FMIPA UNNES Semarang.
