English literature plays a very important role in developing advanced interpretive skills, cultural awareness, and critical thinking, which later contribute to the intellectual and academic growth of students. Therefore, this study analysed the effect of different English literature factors on the academic achievement of students enrolled in English literature study. The main objective of the present research was to examine the effect of academic motivation, academic task value, literature reading attitude, and literature reading self-efficacy on academic achievement. This research also explored the mediating effect of literature reading self-efficacy and the moderating effect of literature reading ability. Quantitative research methodology was used in this study. Data were collected in the form of a questionnaire from students of English literature study through simple random sampling. The questionnaire was designed in a Likert scale format. The gathered data were analysed using SEM-AMOS. The results showed a positive effect of academic motivation, academic task value, and literature reading attitude on literature reading self-efficacy. The findings also show that literature reading self-efficacy has a positive effect on academic achievement. The results demonstrate the mediating effect of literature reading self-efficacy between academic motivation, academic task value, and literature reading attitude on academic achievement. The moderating role of literature reading ability is also statistically established. This study contributes to the literature by examining the mediating effect of literature reading self-efficacy and the moderating effect of literature reading ability.
