Hydel High · 2025–2026 CSEC Mathematics
More candidates. More passes. Stronger movement toward readiness.
The 2026 cohort expanded substantially while producing 5.5 times as many passing outcomes. The results also show a notable shift away from Grade V and a larger group reaching Grade IV—the final grade below the passing threshold.

Cohort comparison
Growth did not dilute the gains.
The number of candidates sitting increased by nearly 30%, yet the pass count grew by 450%. The pass rate rose by 8.76 percentage points, and the Grade V share declined by 27.25 points.

Engagement and mastery
The early signal is about meaningful activity—not simply having an account.
Of the platform records containing scored diagnostics, 5 could be reliably linked to verified exam outcomes. Both passing learners in that linked subset recorded at least one mastery signal of 80% or higher.

Why the linked subset is smaller
This subset is a data-linkage measure, not an enrollment count. A learner needed both a scored Experien Math diagnostic record and a confidently matched examination result to be included. Many other learners used or encountered the platform without producing that exact pair of records.
How to read the evidence
Promising, measurable, and appropriately cautious.
- School-level comparisons use verified 2025 and 2026 CSEC Mathematics outcome records.
- Platform analysis includes only scored diagnostic records that could be reliably matched to a verified exam outcome.
- The linked diagnostic subset is not the number of Experien Math users or the size of the pilot cohort.
- The findings show an association and should not be interpreted as proof that platform activity alone caused an exam result.
High diagnostic mastery was not a guarantee of passing. Teaching, attendance, prior attainment, exam-day conditions, and other factors also shape outcomes. The result is best treated as an early signal worth testing with stronger participation and cleaner longitudinal tracking.
