What is EVV?
Also known as: Electronic Visit Verification
Electronic Visit Verification is the electronic capture of when and where a support actually started and finished, typically by a worker clocking in and out on a phone with GPS. It provides evidence that a claimed support was delivered at the stated time and place, replacing self-reported timesheets.
EVV is not mandated in the NDIS the way it is in some overseas schemes, but it serves the same purpose: it converts a claim from an assertion into a record.
It also protects workers. A verified clock-in is evidence of attendance in a dispute, and location data with a sensible geofence tolerance distinguishes a worker who arrived from one who did not — while a rigid geofence that blocks clock-in on a weak GPS fix simply teaches workers to work around the system.
How EVV works
The worker opens an app on their phone when they arrive at the participant's home or community location and clocks in. The app records the time and the device's GPS position. At the end of the visit the worker clocks out the same way. The system compares both events with the rostered shift and the participant's address.
- A clock-in far from the address, or well before or after the rostered start, is flagged for review
- Actual start and finish times can drive the timesheet and the claim instead of rostered times
- Supervisors see in real time which visits have started and which are late or missed
Why providers use it
The NDIA expects providers to request payment only after a support has been delivered and to keep records of the date, hours and type of each support. Paper timesheets and self-reported times are hard to defend if a payment is questioned. A timestamped, location-stamped record created at the point of care is much stronger evidence.
EVV also protects participants. A missed visit for someone who lives alone is a safety issue, and an unstarted shift is visible within minutes rather than at the end of the pay period.
What EVV does not prove
EVV shows that a worker's phone was at the right place at the right time. It does not show what support was delivered or how the person responded. Pair it with a progress note for each shift, and handle exceptions deliberately: poor reception, community access visits away from the home, and shared devices all produce flags that need a human decision rather than an automatic rejection.
Tell workers and participants what location data is collected, when, and why, and collect it only during the shift.
How Rostery helps
Rostery's carer app records GPS clock-in and clock-out against each shift, flags visits that start away from the participant's address, and keeps the verified times with the shift record for audits and claims.
Questions people ask
Is EVV required for NDIS providers?
The NDIA requires records showing that each claimed support was delivered, rather than a particular technology. EVV is one of the most reliable ways to produce those records.
Does EVV track workers all day?
A well-designed EVV system captures location only at clock-in and clock-out, or during the shift, not outside working hours. Providers should explain what is collected and why.
What happens if a worker forgets to clock out?
Most systems flag the open shift for a supervisor to correct and record the reason, so the timesheet and claim are based on confirmed times rather than guesses.
