It also explored gender differences in EFL enjoyment and the correlation of EFL enjoyment with achievement, autonomy and self-efficacy. Students completed a researcher-developed 36-item questionnaire groping EFL enjoyment, autonomy, self-efficacy and sources of enjoyment. Students' GPAs were used as an index of achievement. Data analysis revealed that the level of enjoyment associating students' learning of English as a FL was high. No differences were found between male and female students in EFL enjoyment. EFL enjoyment correlated positively with achievement, autonomy and self-efficacy. The most frequent reported sources of EFL enjoyment included the realization of learning an important language, teachers' attitudes and positive FL classroom atmosphere.
