Current Examination Context

The March 2026 revised CELE program retains Hydraulics and Principles of Geotechnical Engineering (HPGE) at 30% of the total CELE rating and schedules it on the second day from 2:00 P.M. to 6:00 P.M. The official TOS for this subject contains 50 items.

How to Use the Internal Links

A PRC competency can span more than one repository lesson. The linked lesson is the best starting point, not necessarily the only page needed to satisfy the competency. Cross-review adjacent hydraulics, geotechnical, foundation, and water-resources lessons where a competency spans multiple concepts.

High-Yield Interpretation

The largest TOS allocations are Hydrostatic Pressure / Center of Pressure (16%), Fluid Flow (12%), Stresses in Soil Mass (12%), and Settlement (12%). Those four competencies account for more than half of the subject's TOS weight, but the remaining competencies still contain examinable items and should not be skipped.

Key Takeaways
  • HPGE is 30% of the current CELE.
  • The official HPGE TOS contains 50 items.
  • Use TOS percentages for study allocation, but do not ignore low-weight competencies.
  • Internal links are study starting points; the official PRC TOS remains controlling.
