This study's aim was to explore advanced diploma program students' perceptions about the application and importance of andragogy.

The study findings revealed that the importance of the five andragogical assumptions (motivation, experience, need to know, readiness to learn, and self-directedness) for the learners. There were statistically significant differences ([alpha] = 0.05), due to gender, among the students' perceptions about the learners' need to know; these differences were seen for both the application and importance of the andragogical principles; the variations favored females. Therefore, teachers should employ learning strategies that encourage self-directed learning among students.
