Choose the field of the advancement.

Start with the knowledge the team was trying to develop, then find the closest field in the list. For a manufacturer investigating a new control algorithm, the relevant advancement may be in software or control engineering rather than the product being manufactured.

CRA uses Appendix 1 codes for statistics and resource management. The list does not cover every eligible field, and selecting a code does not determine eligibility.

Read the CRA guide

Connect the code to the claim.

Cedar identifies the project’s field as part of assessing the work and writing the technical report. Tell us what your team was investigating; we’ll help explain the advancement and prepare the claim.
