The complexity of Probability and Statistics Education was intensified by several concerns in the education sector brought by COVID-19 contagion. This study examined the Philippine Kto10 Most Essential Learning Competencies (MELCs) in Probability and Statistics by comparing the content topics and learning competencies with the Kto10 Mathematics Curriculum. This Critical-Qualitative approach of study used curriculum mapping as a method of analysis in the identification of the gaps in the MELCs across the grade level along with lesson continuity and lesson congestion backed up with the experiences and responses of 12-Math teachers (5 Elementary,7 Secondary) who were informants of the study. This investigation found out that the learning competencies in Probability and Statistics of the Kto10 Mathematics Curriculum were reduced (from 89 to 66 learning competencies) across grade level to cope up with the present educational crisis brought by the pandemic. The issuance of Most Essential Learning Competencies (MELCs) arranged in increasing complexity was seen as a good initiative in decongesting the overcrowded Kto10 Mathematics Curriculum. However, gaps were still seen along lesson continuity across grade level particularly in grade 9 (no lesson in Probability and Statistics). This study provides insights among educational authorities and researchers to further explore how the Probability and Statistics are taught across grade level. It uncovers the gaps along lesson continuity and congestion for the need of revision of Philippine Kto10 Mathematics Curriculum.
