A technical problem during an EPSO test creates two jobs at once: protect the test session and build a record that another person can investigate.
“The platform froze” is not enough on its own. EPSO needs timing, context, troubleshooting, provider contact, environment details and impact. The system logs and your account should tell the same story.
This guide uses the general complaint policy and the specific rules in the consolidated EPSO/AD/427/26 notice. Your invitation may add provider-specific steps. Follow it exactly.
The AD5 two-report rule
- Report the issue immediately using the process in the test invitation.
- Contact EPSO through the Single Candidate Portal within three calendar days, counted from and including the day after the test.
You must contact EPSO even if the test provider already opened or resolved a ticket.
First: know what kind of complaint you have
| Problem | Example | Route |
|---|---|---|
| Technical or organisational issue | Platform freezes, test fails to load, timer behaves incorrectly, provider interruption | Immediate invitation procedure plus candidate-account complaint |
| Possible error in an MCQ | No defensible answer, missing information, material translation defect | Question complaint through candidate account within the notice deadline |
| Force majeure | Documented power outage, emergency evacuation or serious medical event | Contact EPSO without delay and provide evidence covering the test date |
| Personal inconvenience | Travel, work meeting, poor time management or ordinary household distraction | Normally not accepted as circumstances beyond the candidate’s control |
Do not combine every dissatisfaction into one vague message. State the category and the remedy-relevant facts.
What to do during the incident
1. Follow the invitation, not memory
Use the support channel and troubleshooting sequence stated in the personal invitation. EPSO’s complaint policy can reject complaints from candidates who skip mandatory checks or fail to troubleshoot as instructed.
2. Report immediately
If the test interface provides a permitted support route, use it. If the invitation provides a provider channel for test-time incidents, follow it. Obtain a ticket, chat reference, email or other trace where the process allows one.
3. Protect exam integrity
The clean-desk rules prohibit mobile phones, writing materials and unauthorised devices. The AD5 general rules allow disqualification for recording online tests or compromising test integrity.
- Do not reach for a prohibited phone.
- Do not photograph or record questions.
- Do not copy test content into a private document.
- Do not leave camera view unless instructions tell you to.
- Do not close the test impulsively.
If an error screenshot is permitted by the provider instructions and can be captured without recording test content, preserve it. If not, rely on provider tickets, platform logs and a precise account written immediately after the session.
4. Notice the impact
The decisive fact is not merely that an error appeared. Record what it prevented:
- Could not enter the test
- Lost access for a measured period
- Timer continued during the interruption
- Could not submit a section
- Could not complete one or more tests
- Provider ended or restarted the session
The three-day clock
For EPSO/AD/427/26, the consolidated notice requires contact through the candidate account within three calendar days. Counting begins on the day after the test, and that day counts as day one.
| Test day | Day 1 | Day 2 | Day 3 |
|---|---|---|---|
| Monday | Tuesday | Wednesday | Thursday |
Submit as soon as the immediate facts are organised. Do not use day three as the drafting day. Complaints received after the deadline are inadmissible.
Build the evidence pack
A complete technical account should include:
| Evidence | What to record | Why it matters |
|---|---|---|
| Candidate identifiers | Full name, candidate number, application number, competition reference | Connects complaint to the correct account and event |
| Session | Date, scheduled time, actual start time and time zone | Lets EPSO match provider logs |
| Test component | Check-in, verbal, numerical, abstract or submission | Locates the affected phase without reproducing questions |
| Timeline | Start, failure, each recovery step, provider contact and final state | Shows duration and sequence |
| Error | Exact message or code, if available | Supports technical diagnosis |
| Environment | Device, operating system, browser and version, connection type | Tests compatibility and configuration |
| Mandatory preparation | Prerequisite check, system check or familiarisation completion | Shows required preparation was completed |
| Troubleshooting | Every instructed action and its result | Shows attempt to resolve the issue |
| Provider contact | Channel, time, agent or ticket reference and advice received | Gives EPSO an independent trace |
| Impact | Lost time, unanswered items, inability to submit or inability to complete | Explains material disadvantage |
A defensible incident chronology
Use short factual entries. Example:
09:52 — Completed check-in and entered verbal test.
10:07 — Interface stopped accepting answer selections. Timer continued.
10:08 — Followed invitation troubleshooting step: refreshed through permitted control. No change.
10:10 — Contacted provider through the instructed channel. Ticket ABC-123 opened.
10:16 — Provider restored interaction. Six minutes elapsed while timer continued.
10:44 — Completed remaining session. Reported impact through candidate account the same day.
Replace every example detail with the truth. Do not estimate a time if logs or messages give an exact one. If time is approximate, label it approximate.
Complaint template
Subject: Technical complaint — EPSO/AD/427/26 — [candidate number] — [test date]
Session: I was scheduled to test on [date] at [time and time zone]. The issue occurred during [check-in/test component/submission].
Issue: At [time], [precise description]. The displayed error was “[exact code or message]”, if applicable.
Actions: I followed the invitation instructions by [steps]. I contacted the provider through [channel] at [time]. The provider reference is [ticket/reference].
Environment: [device], [operating system and version], [browser and version], [connection type]. I completed the mandatory prerequisite check on [date].
Impact: The issue prevented or affected [specific consequence]. It lasted [duration].
Attachments: [provider confirmation, prerequisite result, permitted error evidence, outage certificate or other document].
Request: Please investigate the provider and platform logs and assess the appropriate remedy under the notice and complaint policy.
Do not demand a guaranteed retest. Ask for investigation and the appropriate remedy. EPSO may offer a retest or another measure where evidence shows a justified issue that materially affected test integrity or unfairly disadvantaged the candidate.
Why complaints become inadmissible
- The candidate missed a mandatory prerequisite or system check.
- The candidate did not troubleshoot according to instructions.
- The issue was not reported immediately through the invitation process.
- The EPSO complaint arrived after the deadline.
- The description omitted timing, actions, error or impact.
- The candidate relied only on provider contact and did not contact EPSO.
- The claimed problem arose from breaking test instructions.
Complete the technical rehearsal before test day. The EPSOHQ exam builder can rehearse timed behaviour. The provider’s mandatory prerequisite check proves the actual system environment.
A technical complaint is not an MCQ complaint
If the platform worked but a question may contain an error, use the MCQ-question complaint route.
The AD5 general rules require contact through the candidate account within the same three-calendar-day counting method. Describe the question as accurately as possible and explain the alleged error. Do not publish or circulate the question.
The Selection Board may neutralise a defective item and redistribute its points among the remaining questions for candidates who received it. Disagreement with difficulty is not proof of an error.
After submission
- Save the portal acknowledgement.
- Save the provider reference.
- Keep original evidence unchanged.
- Check the candidate account for requests for more information.
- Answer requests precisely and within the stated deadline.
Do not send repetitive complaints through several routes. Keep one complete record and refer to its existing number.
Evidence is not volume. It is a timeline that can be checked against independent logs.
