This study explored correlation between changes of consciousness and academic achievement about English across the 3 years on junior high school in Japan. The purpose of this study was to develop and assess the item of consciousness about English in junior high school. For that reason, a 3-year longitudinal survey of exploratory factor analysis was conducted, which extracted three factors: “Interest score”, “Quantitative learning score” and “Quality of learning score”. Then, correlation between the three factors and academic achievement was investigated. Results indicated that Interest score and Quality of learning score have a strong correlation with academic achievement for English and the Quantitative learning score had a weak correlation with academic achievement. In mathematics education, there was a strong correlation between interest in the 1
st-year and academic achievement (
Okado et al., 2019), whereas in English, there was a strong correlation between interest from the 2
nd-year to 3
rd-year, and academic achievement. These results suggest that educational activities focusing on the consciousness about English are useful for improving English education of junior high school students.
