This study analyzed the names and ranges of adjective(-i/-na adjectives) and verb conjugation forms in JapaneseⅠ textbooks as part of a study performed to identify whether the textbooks appropriately reflect what is presented in the 2015 Revised Curriculum. This study also analyzed the correlation between questions in evaluation materials and questions in the College Scholastic Ability Test by comparing the questions. The results of the analysis showed that JapaneseⅠ textbooks of the 2015 Revised Curriculum lack unity in the names of adjective conjugation forms and have a lot of problems in terms of the range of verb conjugation forms presented in the textbooks. Overall, JapaneseⅠ textbooks contain different names and ranges of adjective and verb conjugation forms and do not contain many of the conjugation forms that are used in basic communication expressions of the 2015 Revised Curriculum. In other words, this study found that the current educational content is not enough to get students prepared for the College Scholastic Ability Test. These problems need to be considered in improving the appropriateness of questions in the College Scholastic Ability Test and developing textbooks, and efforts need to be made to narrow the content and range in the curriculum of and Japanese textbooks.
