The AACODS checklist was designed by Jess Tyndall to enable evaluation and critical appraisal of grey literature and has the flexibility to be applied to a wide range of resources.
AACODS (Authority, Accuracy, Coverage, Objectivity, Date and Significance)
- Authority: Is the author credible?
- Accuracy: Is it supported by documented and authoritative references? Is there a clearly stated methodology? Is it 'in line' with other work on the same topic
- Coverage: Have limitations been imposed and are these stated clearly?
- Objectivity: Can bias be detected?
- Date: Can't find the date? Rule of the thumb is to avoid such material
- Significance: Is it relevant? Would it enrich or have an impact on your research?
