Time clock for private schools: working-time record without devices
Short answer
A private school can meet the electronic working-time record requirement with a QR code printed and posted on site, which each person scans with their phone. The law requires recording each person's start and end time; it does not require a wall-mounted time clock.
How work happens at a private school
A private school has teachers, hall monitors, administrative staff, maintenance and security, with school hours and hourly teachers. That creates three challenges for measuring working time:
- Hourly teachers have different schedules each day.
- Meetings and events happen outside regular hours.
- There are several campuses.
What the law requires of private schools
Since the 2026 reform, the Federal Labor Law requires recording electronically the start and end time of each worker's workday (article 132, section XXXIV). Failing to do so is fined 250 to 5,000 UMA. The STPS will define who it applies to and what exceptions there will be. The details are in the reform guide.
Multiple locations. Each place needs its own clock-in point. With a QR code, that is one printed sheet per location.
Hourly or temporary staff. They have the same working-hour limits and must also be recorded.
How to record working time at a private school
- Register the workplace and its shifts.
- Print the QR code and post it at the entrance or next to the register.
- Each person scans it on arrival, when leaving for a break and when going home.
- At the end of the day you review what does not add up and download the report whenever you need it.
Example. A teacher with 18 hours a week spread over four days has their own shift. The record compares against that shift, not a general one.
How much is the fine for not recording
How to do the math by hand
The minimum fine is 250 × $117.31 = $29,327.50. The maximum is 5,000 × $117.31 = $586,550. If the penalty is calculated per person, with 5 people the range goes from $146,637.50 to $2,932,750.
Common mistakes at a private school
- Keeping attendance from memory or in a notebook.
- Recording the clock-in and forgetting the clock-out.
- Using a different control at each location.
- Not recording temporary staff because they only come in for one day.
What to check every day and every week
Every day.
- Who did not record their clock-in or clock-out.
- Departures later than planned.
Every week.
- Each person's overtime against the weekly cap.
- Rest days that were actually taken.
How much an overtime hour costs: example in pesos
Suppose a daily wage of $420 on a day shift. The ordinary hourly rate is $52.50. One overtime hour at double time costs $105 and one at triple time, $157.50. If a person works 9 overtime hours in a week in 2027, that is $945 extra.
It is an example to show the calculation, not a reference wage for the sector.
What changes every year, from 2026 to 2030

Frequently asked questions
Does a private school need to buy a time clock?
No. The law requires an electronic record of working time, not a device. An app on a phone complies.
What options are there for recording working time?
An app on each person's phone, a shared tablet or a clock connected to a system. All three comply if they generate an electronic record per person, with a start and an end time.
What happens if someone works at two locations?
Use the same account. Each record is linked to the place where it was made.
Does temporary staff also clock in?
Yes. Their record is kept even if they work only one day.
Is overtime counted by week?
Yes. The cap on double-time overtime is weekly and per person.
