Why Candidates Fail the Measuring Weight Skill
The scale must be zeroed before the resident steps on. Most failures come from not balancing the scale first, not removing shoes or heavy clothing, or reading the scale while the resident is still shifting position. Evaluators also check that the resident is not holding onto anything during the measurement.
