This study aims to measure the progress of the participants’ English proficiency of the ESP program and to compare their achievement with nonparticipants’ achievement. This study examines if the changes in opinions have occurred over the four year period of study (opinion of freshman vs. opinion of senior). It is encouraging to find that both groups of learners have a significant improvement in overall English language skills. Several paired t-test were conducted to explore the specific areas of improvement. In conclusion the implementation of the ESP program will be further refined and will hopefully motivate the students with variety, relevance and an enjoyable learning experience. English teachers will then be able to develop an ESP curriculum that takes the classroom into the real world and brings the real world into the classroom.
