Which training records does a California employer need to keep, and for how long?

When a regulator, a claimant or an insurer asks what you did, the answer is the record. A session that happened and left no trace is, for practical purposes, a session you cannot show. I would rather an employer run one fewer session and keep a clean record than run it twice and be unable to prove either.

From a corporate training seat, the record is also the quality control. If you cannot say who attended, what version of the material they saw and who delivered it, you cannot improve the next session or find the people who missed this one.

This page covers the retention periods I could confirm at the source. It is not legal advice, and I am not an attorney. Where a rule has a floor, keep the record longer than the floor if storage is cheap.

The longest of the applicable periods wins for any one record. A paid training hour is a payroll record for 3 years, so the sign-in sheet that supports it should be kept at least that long.

Use one record per session and one line per attendee. Here is the field set I would use at an employer of 10 to 150 people. The first four are named in the rules above. The rest are my recommendations.

In one place, with one owner, and not in the trainer’s inbox. A shared folder with a fixed naming pattern is enough: year, topic, session date. Put the roster export, the sign-in sheet and the deck in the same folder, and lock editing once the session closes.

If your learning platform produces the log, export it after each session. Platforms change, vendors close accounts and a log you can only reach through a login is a log you may not have when you need it.

Give someone the job of checking the folder monthly. A five-minute check that each session has its three files is the cheapest control in the whole system.

Record the absence as an absence. A blank line for a person who did not attend is better than no line, because the gap is the thing you will be asked about. Then record the make-up session on its own line with its own date.

Part 3 of this series covers scheduling around commutes and shifts, and the practical effect here is that the roster should show who still owes a session and by when. The scheduling page covers how commutes and shifts affect that make-up slot.

Yes. Labor Code 1198.5 gives current and former employees a right to inspect and receive a copy of their personnel records, and the rule was updated effective January 1, 2026 to name training records among the items covered, with a 30 calendar day response period. The statute also carries a $750 penalty for failure to comply.

The workplace violence statute separately gives employees access to their training records within 15 calendar days. If you keep records in a form you can export per person, a request is a ten-minute job. If you keep them as scattered photos of sign-in sheets, it is a week.

A recorded course produces a completion log, and that log is your attendance record. Check three things in it: that it shows the person, the date and the course version, that it shows how long they spent, and that you can export it.

The workplace violence statute requires an opportunity for interactive questions and answers, so a recorded session alone does not complete that training. Record how you offered the Q&A, such as a live office hour, and who staffed it. Why recorded training does not finish explains the completion side of the problem.

Start from today. Do not backfill signatures or reconstruct attendance you cannot support, because a record created after the fact and presented as contemporaneous creates a bigger problem than the gap. If you have partial evidence, such as calendar invitations or a platform log, keep it and label it as what it is.

Then close the gap going forward. Add the ten fields to your next session, assign the owner and run the monthly check. Within a year you will have a record that stands on its own.

If a past session matters, such as a mandatory training for supervisors, schedule the session again and record it properly. A fresh, documented session is worth more than a reconstructed one.

A one-page form for each session and one folder for the year. The form holds the topic, date, trainer, material version, language, format and a roster with a confirmation line. Scan or export it the same day, and save the deck as a PDF beside it.

That is the whole system. It takes about ten minutes per session, and it covers each field in the table above. Add a platform only when the volume of sessions makes the manual version slow.

Part 2 of this series lists the questions I ask before I design any session. The answers to them belong on the record too.

Is a sign-in sheet enough?

It can support the record, but it should be paired with the topic, the trainer, the material version and the language. A sheet with only names and a date answers only part of what the rules ask for.

How long do I keep records for someone who left?

I would keep them at least 3 years after separation, which matches the personnel record rule in Labor Code 1198.5 and the payroll record period.

Do the rules differ for a small employer?

The injury and illness regulation has an exception for employers with fewer than 10 employees, who may keep a log of instructions instead. Most employers in this series are above that line.
