This comprehensive study examined learning progression patterns in integrated Music, Arts, Physical Education, and Health (MAPEH) education across the K-12 continuum in the Division of City Schools of Makati. Using quantitative secondary data analysis, the research analyzed performance trajectories of 24,428 students across 11 grade levels (Grades 2-12) during the complete 2024-2025 school year, examining all four quarters of Performance-Based Assessment data. Results revealed three distinct developmental phases: Elementary Foundation Phase (Grades 2-6), Secondary Transition Phase (Grades 7-10), and Senior Integration Phase (Grades 11-12). System-wide exemplary performance progressed from 26.4% (Q1) to 34.7% (Q4), representing an 8.3 percentage point annual gain. The analysis identified seasonal learning patterns including first-half acceleration, mid-year consolidation, and year-end acceleration phases. The Grade 6 to Grade 7 transition showed consistent severe performance declines across all quarters (averaging -22.1 percentage points), confirming this as the most critical intervention point. Grade 9 demonstrated exceptional annual improvement (+17.7 percentage points), while Grade 10 showed complex recovery patterns. Senior high school students achieved the highest performance levels, with Grade 12 reaching 58.9% exemplary performance by year-end. Findings indicate that MAPEH education requires seasonally-responsive curriculum sequencing, sustained transition support, and year-long differentiated instructional approaches to optimize learning progression across the complete academic calendar.
