Outcomes and Assertions
Computational, Conditional, Qualitative		computational tests (binary pass/fail) and qualitative tests (adjectival tests)Limit cumulative errors at certain levelsFail if critical errorsOutcome based scoring using a tree structure; overall score = lowest scoring outcomeOutcomes given adjectival score; Overall score based on % that have reached adjectival rating
