My Readiness-Based Unofficial Estimate of the Philippines’ PISA 2025 Combined Total
This is a simple linear projection to test if this is sufficient for predicting scores. - Leo De Velez (Aug. 5, 2026)
During the final month of preparation before the PISA 2025 assessment, learners used the Frontlearners online mock exams in Mathematics, Science, and Reading. These mock exams were recreated from officially released PISA items and combined the related assessment modules for each subject into one timed assessment. The underlying report covers online mock exams only and excludes module quizzes and offline results.
Beginning in January 2025, learners practiced individual PISA-style sample problems using Frontlearners’ offline and online materials. On February 24, 2025, the preparation format shifted to complete, timed mock exams in Mathematics, Science, and Reading.
The first week of complete mock-exam use was treated as a familiarization period. The analysis therefore used the seven-day moving-average score on March 3 as the starting benchmark and the corresponding score on March 24 as the ending benchmark.
The combined seven-day moving-average score increased from 58.0% on March 3 to 68.4% on March 24. This represents an absolute improvement of 10.4 percentage points and a relative improvement of 17.93%.
Calculation
Observed improvement = 68.4% - 58.0% = 10.4 percentage points Relative uplift = 10.4 / 58.0 = 17.93% Estimated PISA 2025 combined total = 1,057.4 x 1.1793 = 1,247.0Based purely on the proportional improvement observed in the Frontlearners mock-exam performance indicator, my readiness-based scenario estimate for the Philippines’ PISA 2025 combined total is approximately 1,247 points.
The upward trend indicates that aggregate online mock-exam performance improved during three weeks of repeated complete mock-exam practice. The improvement may reflect stronger understanding of the assessed content, learning from mistakes, improved retrieval, better pacing and time management, greater familiarity with timed assessments, and increased comfort with computers and computer-based testing. The full report similarly shows that the seven-day moving-average score reached approximately 71% before ending at around 68% on March 24.
Because learners repeated the same mock exams, some of the improvement may also reflect familiarity with the questions, remembered solutions, and greater familiarity with the assessment format.
Method note: This is my readiness-based mathematical scenario, not an official OECD forecast. It is based on aggregate online attempts rather than matched learner-level results, excludes offline attempts, and has not been formally linked or equated to the PISA scoring scale. The figure of 1,247 is a constructed total for Mathematics, Science, and Reading, not an official OECD composite score.
