Research about conception and misconception of specific topics in science education is still sightseen among researchers. Ionization energy is one concept that possible generate mis(understanding) for students. Therefore, this study aimed to investigate the understanding of ionization energy among high school students. Totally, 118 students from East Java-Indonesia were invited to an online-Ionization Energy Diagnostic*Modification (IEDI*M) test through survey study. IEDI*M consisted of 12 multiple choices with three-tier items. The findings mapped the main misconceptions of ionization energy, especially for Group 1, Group 2, Period 2, and Period 3 established on the periodic system. By using three-tier tests, the percentages of misconceptions decreased from one-tier to two-tier and from two-tier to three-tier levels. © 2018. Porto Alegre, RS. Brasil.
