CE Questions / What's the difference between a CE hour, a contact hour, and a CEU?
The short answer
A contact hour is 60 minutes of approved instruction, and most boards use "contact hour" and "CE hour" to mean exactly the same thing. A CEU (continuing education unit) is the one that's different: 1 CEU equals 10 contact hours. So a course worth "0.5 CEU" is 5 contact hours, and a 30-contact-hour requirement is the same as 3.0 CEUs. Almost every state board writes its requirement in contact hours, so when a certificate lists CEUs, multiply by 10 before you count it.
The reason this trips nurses up is that providers and boards don't all use the same label. "Contact hour," "CE hour," and (in a CE context) "credit hour" are generally interchangeable: each one is 60 minutes of instruction from an approved provider. Your board's requirement is almost always written in contact hours.
The CEU is the outlier. It's a standardized unit where one CEU represents 10 contact hours. That 10x factor is exactly where people come up short: a certificate that reads "0.6 CEU" looks like barely over half an hour but is actually 6 contact hours, and a nurse who reads a "30 hour" requirement as "30 CEUs" would be chasing 300 contact hours. Read the unit on the certificate, not just the number.
What boards care about is the accredited contact-hour count and the accreditor, not the label a provider prints. If a certificate shows CEUs, the contact-hour equivalent (CEUs times 10) is what you log against your state's requirement.
These states' verified rules state the requirement in contact hours (the standard unit). When a provider's certificate instead lists CEUs, convert at 1 CEU = 10 contact hours before logging it.
| State | Verified rule | Verified |
|---|---|---|
| Virginia | Virginia RN/LPN renewal is a nine-option continued-competency MENU (18VAC90-19-160), not a flat CE mandate, a nationally certified nurse can renew with zero contact hours. | Jun 2026 |
| Tennessee | Menu items include 10 contact hours of Board-approved CE, national certification or recertification, academic credit in nursing, authoring a nursing publication, presenting nursing education, precepting, an employer competency evaluation, volunteer nursing service, a documented nursing-goals project, or a Board-approved refresher program. Because CE is only one of the menu items, a nurse can renew with zero CE by choosing two non-CE items | Jun 2026 |
| Maryland | 1 semester hour of college coursework = 15 contact hours (must be nursing-related, grade C or higher) | Jun 2026 |
| Arkansas | Arkansas offers three options to satisfy CE requirements: 15 contact hours, national certification, or a college course | May 2026 |
| Iowa | 36 CE contact hours are required per renewal cycle for all license types | May 2026 |
| Maine | APRNs must complete 50 contact hours per 2-year cycle, with at least 30 hours in Category I | May 2026 |
| Mississippi | APRNs must complete 5 contact hours related to controlled substances per certification period | Jun 2026 |
| Nebraska | The former '10 of 20 hours must be peer-reviewed' split was repealed (board advisory 9/2025); from 2025 the CE option is 20 contact hours from an approved provider. | Jun 2026 |
| Nevada | APRNs complete an additional 15 contact hours each cycle beyond the base 30 (45 total). | Jun 2026 |
| North Dakota | All licensees must complete 12 CE contact hours within the 2 years preceding renewal | Jun 2026 |
| Rhode Island | Every nurse must complete a one-time (once-per-career) 1-hour Alzheimer's disease CEU, effective August 1, 2019. | Jun 2026 |
For CE purposes, essentially yes: a contact hour is 60 minutes of instruction. The catch is that it has to come from an approved or accredited activity, not just any 60 minutes of reading or work.
Log the contact hours, since that's the unit your board's requirement uses. The two should agree (the CEU figure times 10 should equal the contact hours); if they don't, trust the accredited contact-hour count.
The standard definition (IACET) is 1 CEU = 10 contact hours, and accredited nursing-CE providers follow it. If a provider uses a different conversion, treat it as a reason to confirm the activity is genuinely accredited before relying on it.
