For papers or reports, the reference material is good but incomplete. The work partially engages the major scientific principles embodied in the topic being explored. The work generally relates to the assigned task, but gaps and problems are prominent and interfere with its effectiveness. Data or examples are poorly chosen and do not contribute substantially to the scientific analysis. The analysis has serious gaps.
Reference material is shallow or only marginally appropriate.

The analysis is grossly incomplete, and reference material is absent or inappropriate. There is little or no meaningful effort in evidence.
