Scoring method: Results are reported as a scaled score from 100 to 1,000 using a compensatory model, so only the overall score must reach the minimum; section-level feedback is informational. Unscored pretest items are not identified and do not count; unanswered questions are scored as incorrect with no penalty for guessing. SCS-C03 has 50 scored and 15 unscored questions and a minimum passing score of 750; ordering and matching items earn credit only when fully correct.. The exam may include unscored pilot questions - treat every question seriously.
