It is the policy of The Chronicle and SFGate.com to promptly correct errors of fact and to promptly clarify potentially confusing statements. The policy applies to all newsroom employees.

Errors, whether brought to our attention by readers or staff members, will be corrected quickly and in a straightforward manner.

It will be considered unprofessional conduct and a breach of duty if employees are notified of possible errors but fail to respond. Correcting errors and clarifying ambiguous information is a virtue and an admirable practice.
