The Ateneo de Naga University Intensive English Program (AdNU-IEP) is designed primarily for foreign nationals who have serious desire to improve their English Language skills for educational and professional applications. This challenging English as a Second Language (ESL) program is useful to working professionals and to students preparing for university study or professional programs. Foreign nationals who are already accepted in the mainstream programs of the university, but encounter language difficulty posed by English as the medium of instruction, are highly encouraged to undergo IEP.

This program offers four sessions yearly. Each sessions lasts twelve weeks. In one year, ESL students should be able to progress through the three-level core program. Classes meet three hours daily, five days per week.

The course of study is based on in an integrated skills approach with listening, speaking, reading, writing, and grammar components with emphasis on Functional English. Fluency and accuracy in both spoken and written English are emphasized at different levels. Classes range from six to fifteen students. The small class size allows each participant a maximum amount of individual attention and an opportunity to develop conversational skills.

Intensive English classes at any specific level, beginning through advanced, will depend on sufficient enrollment. Students must be open to accepting a morning (9:00 am - 12:00 pm), afternoon (2:00 pm - 5:00 pm), or evening schedule (6:00 pm - 9:00 pm) as assigned by the Program Coordinator. Enrollees though, may identify their preferred schedule which could be arranged by the teacher/s who would handle the classes after consultation with the Program Coordinator.
