This study examined the integration of the Whole Brain Learning Approach (WBLA) in the College of Teacher Education of President Ramon Magsaysay State University, Castillejos Campus , Zambales, Philippin es. Anchored on Herrmann’s Whole Brain Theory, the study analyzed how instructional delivery and learning experiences reflect internal, external, procedural, and interactive learning dimensions. An explanatory sequential mixed – methods design was employed. Qu antitative data were gathered from 180 student – respondents selected from a population of 344 using Slovin’s formula and from all 16 faculty members through total enumeration. A researcher – made questionnaire was used to assess instructional delivery, teache r strategies, student learning experiences, and WBLA implementation factors. Open – ended responses were analyzed thematically to explain and extend the survey results. Findings showed that student engagement, instructional strategies, and the use of brain – based principles were generally rated Excellent by faculty. Teachers reported consistent use of WBLA strategies, particularly in procedural, interactive, and internal learning, while students reported strong learning experiences across all four dimensions. However, differentiated instruction, data – informed teaching, technology integration, environmental enrichment, and wellness – oriented planning were less evident. Qualitative findings identified lack of teacher training, resistance to change, time constraint s, limited resources, assessment misalignment, and classroom management concerns as major barriers. In response, the study proposed the WHOLISTIC Program, which emphasizes faculty development, lesson design support, institutional policy alignment, resource provision, monitoring, and research. The study concludes that WBLA can strengthen teacher education when implemented systematically, supported institutionally, and aligned with evidence – based instructional design.
