- Review the adapted version and make the necessary changes.
- Place scores of both the translated/adapted version and the original Griffiths III on a common scale.

- Validity, which includes investigations into bias and the construct equivalence of Griffiths III in the languages and cultures of interest
- Reliability

- Document the process and follow the directions of the joint ARICD and HOgrefe panel to prepare the manual, test materials and protocols for test users.
- Notify ARICD when the adopted/adapted version of Griffiths III is ready for use so that it can be listed by ARICD and Hogrefe.
It should be noted that sometimes in the adaptation process, to improve content and construct coverage that enhances the suitability of Griffiths III for use in another country or cultural context, it is necessary for:
- some items to be discarded and replaced by more culturally appropriate, new items;
- additional items to be added.
