CDT exam-day guide
CDT · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the original, unexpired ID in the name you registered under. A photocopy or a photo on your phone is normally not accepted. Confirm with the provider which specific ID forms they accept and whether a secondary ID is required.
Admission / appointment confirmation
Print or download the confirmation email or scheduling notice showing your test date, time, and test center or remote-proctoring link. Have it accessible before you arrive or log in.
Your registration login or candidate ID number
Know your candidate ID and the username/password for the testing vendor portal in case the site needs to look you up or you must reschedule on short notice.
Directions, parking, and travel buffer
Scout the route the day before and plan to arrive well ahead of your appointment time. For remote testing, confirm your link and check-in steps at least a day in advance. Ask the provider how late arrival is handled - do not assume a grace period.
Permitted calculator or scratch materials
Many computer-based exams supply an on-screen calculator and erasable note board and prohibit bringing your own. Confirm with the provider exactly what is allowed before you pack anything.
Personal items plan (phone, watch, bag, outerwear)
Expect to store personal belongings in a locker or leave them outside the testing room. Smartwatches and phones are typically not permitted at the workstation. Confirm the provider's storage arrangements.
Medication, glasses, and accessibility arrangements
Bring anything you need medically, and confirm in advance whether an approved accommodation or extra time has been granted and how to invoke it on test day. Ask the provider how to request accommodations if you have not already.
Test-day logistics: food, water, rest
Eat normally, hydrate moderately, and protect your sleep the night before. Avoid a heavy meal right before the appointment and know whether a break will be available.
Review your own weak-topic notes only
Bring a one-page summary of formulas, terminology, or procedures you personally keep forgetting. Do not attempt to learn new material in the last 24 hours.
Read the provider's candidate handbook / testing rules
The handbook is the authoritative source on ID, prohibited items, break rules, scoring, and score reporting. Read it once in the final week and note anything unclear to ask about.
Plan the day
Stop adding new material. Do timed practice sets under exam-like conditions, review explanations for missed items, and consolidate a single page of high-yield reminders. Confirm your appointment time, location or remote link, and ID requirements. Get a full night's sleep each night rather than cramming.
Light review of your own summary page only, plus a quick pass over exam mechanics (number of questions, time limit, whether sections are timed separately, how to flag and revisit questions). Lay out ID, confirmation, and clothing. Confirm travel time and set two alarms. Stop studying early enough to sleep at your normal hour.
Eat a normal breakfast, re-check the appointment time and route, and arrive early - for remote testing, complete the system/equipment check and room scan well before the start time. Leave your phone and smartwatch stored as directed. Use the restroom before you are seated.
Present your ID and confirmation, follow the proctor's instructions exactly, empty pockets as directed, and note where the clock is and how the timer counts down. Ask the proctor any procedural question before the exam begins, not during it.
Do a quick first pass answering questions you know, flagging the rest. Read the call of the question before the answer choices, and watch for negatively worded items and 'except'/'least likely' phrasing. Budget time from the total, not per question; leave a few minutes to review flags and confirm no item is left blank if the exam does not penalize guessing. Take any permitted break only if it will not cost you needed time.
Note your provisional result if one is given, keep your score report or confirmation, and record anything you want to follow up on. Ask the provider how and when official results are released and what the retake policy is.
Rules to check
Bring valid, unexpired government-issued photo ID matching your registration name; without acceptable ID you may be turned away and your fee forfeited. Confirm accepted ID forms with the provider in advance.
Do not bring phones, smartwatches, or other electronic devices into the testing room unless the provider explicitly permits them. Assume they must be stored; unauthorized devices can void your score.
Follow all proctor instructions. Talking, looking at another candidate's screen, or leaving the testing area without permission may be treated as misconduct. Confirm the provider's exact misconduct and dismissal policy in the candidate handbook.
Break availability, break timing, and whether the clock runs during breaks vary by provider. Ask before test day and, if breaks are permitted, keep them short.
Scoring rules - whether unanswered questions count as wrong, whether there is a penalty for guessing, and how the exam is scaled - are set by the provider. Read the handbook rather than assuming; if the exam does not penalize wrong answers, answer every question.
Most certification exams prohibit disclosing, reproducing, or discussing specific exam content, including on social media or study forums. Honor the confidentiality agreement you accept at check-in.
Arrive early. If you are late, admission is at the provider's discretion and may be refused; confirm the late-arrival and rescheduling rules with the provider.
If you need an accommodation, extra time, or a rescheduled date, request it through the provider's published process well before your appointment - do not raise it for the first time at check-in.
