The effectiveness of an English curriculum, called Traveller, newly implemented in the Kingdom of Saudi Arabia was investigated. The research identified advancements in the new curriculum that contributed to better achievement of academic goals in English language study. In 2011 the Ministry of Education introduced new teaching approaches; of the four new methods that the Ministry of Education adopted in secondary schools, this research focused on the Traveller curriculum. Senior secondary female students and English language teachers were chosen as participants to evaluate this new method. Both quantitative and qualitative research methods were applied. The results showed that the Traveller method has brought remarkable benefits to the teaching and learning process. The majority of the students thought it was a valuable learning experience, and students worked harder because they found that the course challenged them appropriately. Therefore, this research shows that the introduction of this new approach positively impacted student achievement. Furthermore, the credit system showed success, as 63% of the students agreed that it increased their desire to learn.
