I think you might find that everybody does something different. I have been the CRA Officer at 4 banks. Here were the titles:
1. Market Research Officer appointed as the CRA Officer (large bank)
2. Community Development Officer (CRA primarily) performing marketing activities. (large bank)
3. First VP - CRA Officer - no other duties besides CRA officially, but actually tried to start a Marketing Department (ISB)
4. Marketing Officer appointed as the CRA Officer (small bank)
5. Training Officer appointed as the CRA Officer. (ISB)
I think the title follows me because I know and like the spirit of the CRA regulation.
I am responsible for updating the public file, but the Compliance Officer oversees the data collection and data integrity processes.
