ICS/SCADA exam-day guide
ICS/SCADA · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the exact ID the registration was made under, with a name match. If your ID name differs from your registration (nickname, married name, transliteration), confirm with the provider in advance how to handle it; do not assume a secondary document will be accepted.
Appointment confirmation and test-center address
Save the confirmation email or booking reference offline (screenshot or printout). Verify the street address, building, and entrance the day before, since test centers are often inside office parks or training facilities with poor signage.
Arrival time buffer
Plan to arrive well before the scheduled start; many providers require check-in and ID verification before the timer begins. Confirm with the provider the exact cut-off after which a late arrival forfeits the seat and fee.
Permitted-aids policy confirmed
Ask the provider whether any reference material, formula sheet, or on-screen reference is allowed for this ICS/SCADA exam. Assume nothing is allowed unless explicitly stated. Most vendor and certification exams are closed-book.
Calculator and scratch materials policy confirmed
Confirm whether an on-screen calculator is provided and whether physical calculators or scratch paper are permitted. If physical materials are allowed, they are usually supplied and collected by the proctor, not brought by you.
Personal items plan
Expect phones, smartwatches, bags, and notes to be stored outside the testing room. Leave anything you do not need at home or in the car. Confirm with the provider whether a locker is available.
Break and timing policy reviewed
Check whether the exam is one continuous block or has scheduled or optional breaks, and whether the clock stops during a break. Confirm with the provider, as policies differ between remote and in-person delivery.
Remote-proctoring setup tested (if applicable)
If testing online, run the system check on the same machine and network you will use on exam day: camera, microphone, browser lock, and bandwidth. Have a wired or stable connection and a backup plan such as a phone hotspot or rescheduled slot.
Scoring and retake policy understood
Know the passing score, whether results are immediate or delayed, how many attempts are allowed, and any waiting period between attempts. Confirm with the provider; these details vary by certification body and are not guessable.
Rest and logistics the night before
Protect sleep, eat a normal meal, and avoid last-minute cramming of unfamiliar topics. Confirm travel time to the center or set an alarm for a remote session, and clear your workspace of notes if proctored remotely.
Needs review: exam version and blueprint
Confirm with the provider which exam version or blueprint applies to your booking, since ICS/SCADA certification content changes between releases. Do not rely on third-party summaries of the current objectives.
Needs review: accommodations
If you need extra time or other accommodations, confirm with the provider that the request was approved and recorded on your booking. Accommodation requests usually have lead times and may not be granted on exam day.
Plan the day
Stop learning new material. Review your own weak areas using your notes and hands-on experience: network segmentation between IT and OT, Purdue model levels, industrial protocols and their security weaknesses, PLC and HMI exposure, and incident response in environments where availability outranks confidentiality. Re-read the provider's candidate handbook for rules on ID, breaks, and scoring. Confirm your appointment time, location, and any remote-proctoring requirements, and resolve open questions with the provider now rather than on exam day.
Do a light review only: skim your summary sheet, re-check key distinctions such as safety instrumented systems versus basic process control, and passive versus active monitoring in OT. Prepare your ID and confirmation, lay out clothes and travel plan, and test remote-proctoring equipment if applicable. Sleep on a normal schedule. Avoid alcohol and late-night study, since fatigue hurts performance on scenario-based questions more than one extra hour of review helps.
Eat a normal meal and arrive with time to spare. Bring only permitted items and the required ID. At the center, follow check-in and ID verification, store personal items, and read the proctor's instructions on the interface, timer, and how to flag questions. If remote, close all other applications, silence devices, and keep your face and workspace visible per the proctor's rules.
Read each question fully and watch for qualifiers such as 'best', 'most likely', and 'first'. For scenario questions, identify the environment (IT versus OT), the constraint (safety, availability, confidentiality), and the role described before choosing. Answer easy questions first, flag long scenarios, and return to them. Eliminate clearly wrong options, then choose the answer that best fits the stated constraint rather than the most technically impressive one. Pace yourself against the remaining time and question count, and reserve the last few minutes to review flagged items and confirm no question is left blank if the exam does not penalize guessing.
Rules to check
Present the ID required by the provider and confirm in advance what forms are accepted. If your identification documents are unclear, contact the provider before exam day rather than at check-in.
Do not bring unauthorized materials into the testing room, including notes, phones, smartwatches, and study aids. If you are unsure whether an item is permitted, ask the proctor or confirm with the provider beforehand.
Follow all proctor instructions, including seating, screen sharing, and room scans for remote sessions. Attempting to communicate with others or capture exam content is grounds for termination of the session.
Confirm the break policy with the provider before exam day. If breaks are allowed, understand whether the clock runs during them, and expect re-verification of identity on return.
Understand the scoring model before you start: passing score, whether questions are weighted, and whether unanswered questions count against you. Confirm with the provider rather than assuming a guessing strategy.
If a technical failure occurs, stop and notify the proctor or support channel immediately and note the time. Do not attempt to troubleshoot in a way that could be seen as leaving the secure environment; confirm with the provider how incidents are documented and rescheduled.
Results, score reports, and retake eligibility are governed by the provider's policy. Confirm how and when results are delivered and what the retake waiting period is, and keep your score report for your records.
