At least once a year, and again whenever your circumstances change. An update also means telling the people who carry out the plan, keeping every copy current and, for in-depth security training, training within 90 days.

Set the review date
Section 172.802(c) calls for a review at least once each year. Revise or update the plan as needed to match changing circumstances. §172.802(c)
Pick a review month and one person to collect changes. New locations, new duties or new shipment setups are good reasons to look again. That checklist is our suggestion. It is not a list of legal deadlines.
Keep the written plan and its risk assessment for as long as they are in effect. §172.802(c)
Finish the update after the wording changes
Tell every employee who carries out a revised or updated plan. Keep every copy of the plan current as of the latest revision date. §172.802(c)
If you revise the plan during the three-year training cycle, required in-depth security training must happen within 90 days after the revised plan takes effect. §172.704(c)(2)
Keep the review decision, revision date, copy list and training follow-up in one place. A dated note helps the next reviewer see what was checked. Saving the new file does not finish the training task.

Questions and answers
Is the yearly review the same as the three-year training cycle?
No. Track two jobs. The yearly review asks whether the plan is still current. The training check asks whether the affected employees have learned their duties.
