The sources behind every figure
Critical Care Cert Hub is a study site for nursing specialty exams with no tie to the boards that write them. No author is named, and no clinical credential is claimed for the site. Nothing here has been reviewed or endorsed by a certifying board, an association or the testing vendor.
Primary documents only
Every exam figure is copied from the certifying body's own publication: the test plan or content outline, the candidate handbook, the fee and recertification pages and the yearly statistics. For this site that means ABNN for the SCRN, BCEN for the TCRN, CFRN and CTRN, and the AACN Certification Corporation for CMC, CSC and the CCRN exams. Transport employer rules come from the CAMTS accreditation standards, course details from ENA and the Society of Trauma Nurses.
Each fact is stored once, with the address of the document, the page where it sits and the date of reading. Tables, comparisons and exam pages all print from that single record, so the TCRN fee on the BCEN page cannot disagree with the one on the TCRN cost page. Most records were read on November 11, 2026.
Rules with a date attached
Several rules on this site change on a known date, and the pages are worded so that they stay true on both sides of it:
- the CMC and CSC test plans, revised for exams taken on or after November 19, 2026, with the old plans kept as history;
- the CMC passing score, which AACN may restate for the new exam form, so it is marked as provisional;
- BCEN recertification, where the accredited share of contact hours rises for applications from January 1, 2027;
- the CAMTS 13th edition standards of September 29, 2026, which make CFRN or CTRN a requirement after two years on a transport crew.
The status line at the top of every page shows the next dated change and when facts were last read.
Stroke here, trauma there: who teaches what
The four exams overlap clinically, so topics are assigned by setting rather than repeated: stroke in every phase belongs to SCRN, injury by mechanism to TCRN, anything that depends on the aircraft, the ambulance or the distance to definitive care to the CFRN section, and medical cardiology to CMC. Other pages give the topic one line and a link to its owner.
Three boards, three kinds of pass data
AACN reports first-time results for each exam. ABNN reports how many people tested and passed, repeat candidates included, and states its own percentage. BCEN reports only counts of exams delivered, passed and failed. We print the counts as published; where a page shows a BCEN percentage, it is passes over the total of passes and fails, labeled as our calculation. Mixing those three numbers in one ranking would mislead, so no page here ranks the exams by pass rate.
Two reviewers for every practice question
The bulk of the practice items originate in the banks our exam-prep apps use. Before a question is published, a first reviewer answers it without the key, compares, checks the keyed answer against the current outline and guideline (the AHA/ASA stroke guidelines, ATLS and TNCC for trauma, ACC/AHA guidance for heart failure and acute coronary syndromes, ASTNA and CAMTS material for transport) and writes an explanation for every option. A second reviewer, working separately, grades it against a fixed list: one defensible answer, no clue in the wording or the option lengths, explanations that agree with the key. Items that fail are fixed or replaced and reviewed again. Questions that repeat another one on this site, or match one already published elsewhere, are dropped.
Decisions that stay with the board
Eligibility rulings, seat bookings, score reports and renewals are the board's business alone; if its current wording and ours disagree, follow the board. Whether an employer or a transport program accepts a credential is that employer's decision. Nothing on these pages is clinical advice for a real patient.
