Electricity is a part of physics course in the engineering. Concept mastery on the topic of electricity is very useful and important for physics course. Electrostatic and electrodynamics are two topics in electricity that require representation in engineering that can be used to solve a problem. However, concept mastery tests on the topic of electricity rarely use all four types of representations, such as more use verbal and mathematical representations. The purpose of this research is to develop validate the concept mastery test on the topic of electricity which consists of 25 test items multiple choice. The concept mastery test was tested on 50 students from one of the universities in Lampung. The concept mastery test development uses the DDR method with four phases, namely analysis, design, development, and evaluation. The result of this research obtained a valid and reliable concept mastery test that is enriched with all four types of representations. © 2020 IJSTR.
