Common Traps
Fixed percent trap
No public cut score ≠ Criterion-referenced scoring
Formula sheet trap
Calculator provided ≠ Formula sheet banned
Beta item trap
Beta hidden ≠ Answer every item
Scaffold height trap
Scaffold is 10 ft ≠ General construction 6 ft
Inspection trap
Inspection finds conditions ≠ Audit tests systems
PPE trap
PPE is last ≠ Eliminate first
Investigation trap
Find system causes ≠ Avoid blame focus
