Abstract In order to measure the students' comprehension level of acid-base reaction, and to diagnose the students' alternative framework, this paper developed test tool for understanding the concept of acid-base reaction based on the RASCH model, and used this tool to test 752 students. The analysis showed that the test results had certain reliability and validity. The test results also showed that senior high school students' conceptual understanding of acid-base reaction increased with the grade, but there were many alternative frameworks in different comprehension levels.
