Distinguish the consequences when a child passes the cognitive test but fails the oath-understanding test from the consequences when the child fails the cognitive test.

The two tests perform different functions. The cognitive test determines whether the child is competent to give evidence at all. The oath test determines whether a cognitively competent child’s evidence can be sworn or must be unsworn, with corroboration required for the unsworn form under the material. **Key takeaway:** Failure of the first test bars testimony; failure of the oath test may lead to unsworn testimony. **Glossary:** Oath test: inquiry into whether the child understands the nature of an oath.
