How long must background investigation records be maintained?

The correct answer is that background investigation records must be maintained for two years. This timeframe is established to ensure that there is sufficient documentation available for reference, especially in situations where an individual's background could be relevant to ongoing assessments or compliance with departmental policies. Maintaining these records for two years allows law enforcement agencies to review past records when considering promotions, transfers, or when addressing any issues that may arise post-hire.

Shorter durations, like one year, would not provide enough of a historical perspective for evaluating the integrity and suitability of personnel within the department, while longer durations such as three or five years might create unnecessary storage burdens and complications in record-keeping processes. The two-year retention strikes a balance between having enough time for review and oversight without overextending the duration of record maintenance.
