CCHT-A exam-day guide
CCHT-A · Prepare for the day ahead.
Your checklist
Unexpired government-issued photo ID
Bring a driver's license, state ID, or passport with a photo and signature. The name must match the name on your exam registration exactly. If your name has changed since you applied, bring the supporting documentation (e.g., marriage certificate) and confirm the requirement with the certifying body before test day.
Exam authorization / admission notice
Print or save the scheduling confirmation and any authorization-to-test notice you received from the certifying body. Some centers ask for the confirmation number at check-in. Confirm with the provider whether a printed copy is required or an electronic copy is acceptable.
Appointment confirmation with exact address, date, and check-in time
Verify the testing center location the week before; test centers in the same metro area are easy to confuse. Note the check-in time on your confirmation, not the exam start time.
Transportation and parking plan
Preview the route and parking or transit options. Aim to arrive at the check-in time stated on your confirmation, and build in buffer for traffic, security screening, and check-in paperwork.
Layered clothing
Testing rooms are often cold. A light layer you can remove is useful; heavy outerwear, hats, and scarves may need to be stored in a locker. Confirm the center's policy on outerwear with the provider.
Glasses or contact lens supplies if you wear them
You will be reading a computer screen for a long sitting. Bring a case and solution if you wear contacts.
Approved accommodation letter (if applicable)
If you were granted extra time or a separate room, bring the approval documentation. Accommodations generally must be requested and approved well before the exam date - confirm the deadline with the provider.
Confirm the calculator and scratch-paper policy
Many computer-based exams provide an on-screen calculator and erasable note board, and prohibit bringing your own. Ask the certifying body or testing vendor in advance so you know what to expect for calculation-style items. Do not assume personal calculators are allowed.
Leave prohibited items at home or in the car
Phones, smartwatches, fitness trackers, notes, textbooks, and bags are almost always banned from the testing room. Ask the provider for the full prohibited-items list and locker policy.
Review the official content outline and formula set
Use the certifying body's published content outline to target final review. Rehearse dialysis-related calculations you expect to see (e.g., urea reduction ratio, percent reduction of urea, delivered Kt/V interpretation, sodium modeling math) on paper at home - you will not be able to bring study materials into the room.
Confirm the reschedule/cancellation policy and fee
Policies and notice windows vary. Check your confirmation materials or contact the provider before making any changes to your appointment.
Plan a normal meal and hydration before arrival
Eat a usual meal beforehand. Food and drink are typically not allowed at the workstation, so plan to finish them before check-in. Confirm the center's break and snack policy with the provider.
Plan the day
Re-read the official content outline and your weak-topic list. Do targeted review only - no new material. Reread your own notes on water treatment, dialyzer reuse and reprocessing, machine alarms, access care, and calculations.
Confirm your appointment date, time, and testing center address, and re-check the ID requirement and prohibited-items list with the certifying body or testing vendor.
Do one short practice set under timed conditions to rehearse pacing, then stop. Avoid cramming new content in the last 48 hours.
Confirm transportation and, if needed, a backup plan; decide what you will wear and what you will carry.
Pack your ID, confirmation, and accommodation letter in one place. Lay out clothes. Charge your phone but plan to store it - not carry it into the room.
Do a light review of formulas and high-yield safety topics (dialysate composition and mixing, conductivity and pH checks, chlorine/chloramine testing, air embolism and hemolysis signs, needle dislodgement). Stop early.
Eat a normal dinner, limit caffeine and alcohol, and go to bed at your usual time. Do not start a new topic the night before.
Eat breakfast, hydrate, and arrive at the check-in time on your confirmation - not the exam start time. Bring only your ID, confirmation, and approved accommodation letter.
At check-in, expect identity verification, possibly a photo and signature, and a rules briefing. Ask where lockers are and store everything prohibited before entering.
Read the full question and all options before answering. For calculation items, estimate the answer first, then compute, and check that units and rounding make sense.
Flag and move past items you cannot resolve in about a minute; return to them after finishing the rest. Watch the clock roughly per-question rather than staring at it.
If you need a break, raise your hand and follow the proctor's instructions - unapproved leaving of the testing room can end your session. Confirm the break policy with the provider before test day.
Before submitting, review all flagged items and confirm no item was left blank unless the exam penalizes wrong answers (it usually does not - confirm with the provider).
Rules to check
Bring valid, unexpired government-issued photo ID. The name on the ID must match your registration; if it does not, you may be refused admission and your fee may be forfeited.
Arrive at the check-in time stated on your confirmation. Late arrivals may be turned away or given reduced testing time - confirm the provider's late-arrival rule in advance.
Do not bring phones, smartwatches, notes, books, or bags into the testing room. Store them as directed; possession of prohibited items during the exam is typically treated as misconduct.
Follow all proctor instructions. Unauthorized leaving the testing area, talking, or looking at another candidate's screen can result in your exam being voided.
Request any disability accommodation well before the exam date through the certifying body, not at the test center on the day of the exam.
Breaks and their effect on your remaining time vary by provider. Ask before test day whether the clock stops during a break.
The exam is scored against a predetermined passing standard rather than against other candidates; results reporting method and timing are set by the certifying body - confirm how and when you will receive your score.
If you believe a testing irregularity occurred (equipment failure, disruption), report it to the proctor immediately and follow up in writing with the certifying body, since deadlines for appeals may apply.
