Training Matrix Software
Use expiry windows to plan ahead
Training matrix admin becomes easier when renewals are grouped into clear windows. A simple 30, 60 and 90 day view helps managers see what needs attention before work is affected.
The calculation
expiring records = certificates with expiry date inside the review window
For example:
- 30 day window: urgent renewals.
- 60 day window: bookings and reminders.
- 90 day window: forward planning and budget checks.
Add workload time
Estimate admin effort with:
monthly training admin hours = expiring records x average minutes per renewal / 60
If 18 certificates expire this month and each renewal takes 20 minutes to chase, upload and check, the admin load is:
18 x 20 / 60 = 6 hours
What to track
Track the person, role, certificate name, expiry date, evidence file, status and owner. Make sure expired or missing records are visible before they affect site access.
How Zektrx helps
Zektrx helps contractors track training records, certificate expiry, evidence and follow-up actions so teams are not managing renewals from scattered spreadsheets.

Related FAQs
Does this replace noise monitoring?
No. Use competent monitoring and legal guidance for exposure assessment and controls.
From Noise Exposure Calculator
What if there are multiple tools?
Assess each exposure and combine them with a suitable occupational noise method.
From Noise Exposure Calculator
What is trigger time?
Trigger time is the time the tool is actually vibrating in the worker's hands, not the whole task duration.
From HAVS Calculator
Should I use declared tool values?
Manufacturer data can be a start, but measured site data is better for risk assessment.
