Learning styles have a big contribution to the academic performance of a student. Awareness of one's learning styles will help a person maximize his potential in accumulating learning to the best of his ability with the use of his preferred learning styles. The teacher's awareness of the student's learning styles will help him/her select teaching strategies that would maximize the student's learning potential. This descriptive research analyzed the learning styles of the sophomore students of PUP Laboratory High School. Specifically, the researchers sought answers to the following sub-problems: 1. What is the description of the respondents in terms of selected personal variables? 2. What is the academic performance of the respondents? 3. Is there a significant difference in the academic performance of the respondents when grouped according to the selected personal variables? Findings show that there are more female students than males; that most of the respondents came from families having PHP5001-10,000 monthly family income; and, that although they use varied learning styles, the most dominant is the auditory learning style. Academically, students are average learners. Their academic performances significantly differ when grouped according to gender, socio-economic status, and learning styles. With these findings, the researchers recommend that the PUP-LHS should maintain academic and non-academic programs which addresses the strengths and weaknesses of students of both genders; that the school should be involved more with the community programs to know clearly the socio-economic status of students; that there should be intensive trainings which will enhance the auditory skills of both the teachers and the students; and, that the students should also be responsive to the PUP-LHS' commitment in giving the best educational services for them to improve their academic performance. Follow-up studies are also being recommended.
