What Is Covered in CNA Classroom Theory? Washington's 35-Hour Requirement

CNA classroom theory hours in Washington are set by WAC 246-841A-440 at a minimum of 35 of the 108 total training hours, alongside 33 skills lab hours and 40 clinical hours. Those 35 hours must deliver the Washington State Board of Nursing (WABON) common curriculum, which is organized around the 12 core competency areas listed in WAC 246-841A-400: the nursing assistant role and regulations, resident rights and independence, communication, infection control, safety and emergencies, basic nursing skills, basic restorative services, personal care, life transitions, developmental disabilities, mental health and social service needs, and cognitive impairment. Theory can be taught in person, live online, or in a board-approved hybrid format; the skills lab and clinical hours cannot.

Where theory fits in the 108 hours

Theory is the smallest block by a narrow margin, but it is the foundation the other two build on. The rule does not allow a student to perform any skill on a resident until the student has demonstrated it to an instructor, and the reasoning behind each skill step is taught in theory first. In a 4-week program such as Huduma's CNA Traditional course, theory is front-loaded so that lab practice can begin within the first days.

The 12 core competencies, explained

WABON's common curriculum spreads content across the areas below. Programs decide the exact hour allocation per topic, so the descriptions here explain what each area contains rather than assigning hours.

The nursing assistant role and regulations

Students learn what an NA-C may and may not do under Washington law, the chain of command in a facility, the difference between the NA-C and Nursing Assistant-Registered (NAR) credentials, and how the Washington State Department of Health (DOH) issues and disciplines credentials. This unit is where the annual birthday renewal, the background check, and the reporting duties are introduced. The legal framework is summarized in WAC 246-841A explained.

Resident rights and promotion of independence

Federal nursing facility rules give residents rights to privacy, dignity, choice, freedom from abuse and restraint, and participation in care decisions. Theory covers how an aide protects those rights in daily tasks, for example knocking before entering, offering choices in clothing, and encouraging a resident to do as much self-care as possible.

Communication and interpersonal skills

This unit covers verbal and nonverbal communication, communicating with residents who have hearing, vision, or speech loss, reporting observations to the nurse, and documentation. It also introduces the language of the skills test, where explaining the procedure to the resident is a scored step in nearly every skill.

Infection control

Standard precautions, hand hygiene, personal protective equipment, the chain of infection, isolation categories, and handling of linens and sharps are all here. Federal rules require this content, along with communication, safety, resident rights, and independence, to be taught before any student has direct contact with a resident.

Safety and emergency procedures

Body mechanics, fall prevention, fire and disaster response, choking response, and recognizing changes in condition that require immediate reporting. Programs usually pair this unit with a CPR certification requirement, which most employers also expect.

Basic nursing skills

Vital signs (temperature, pulse, respirations, blood pressure), height and weight, intake and output, positioning, admission and discharge, and observation. The numbers matter: students learn normal ranges and what readings to report.

Basic restorative services

Range of motion, ambulation with assistive devices, transfer techniques with a transfer belt, and the purpose of restorative care in preventing contractures and pressure injuries.

Personal care

Bathing, oral care, grooming, dressing, toileting, perineal care, skin care, and feeding assistance. Theory covers the "why" of each step; the lab covers the "how."

Life transitions

Aging changes, chronic illness, end-of-life care, hospice concepts, grief, and postmortem care.

Developmental disabilities, mental health, and cognitive impairment

Three separate competencies address residents with developmental disabilities, residents with mental health and social service needs, and residents with dementia or other cognitive impairment. Content includes behavior as communication, validation and redirection techniques, and safety for residents who wander.

How theory is delivered

WAC 246-841A-440 allows three formats for theory, each with a student-to-instructor limit:

• In person in a classroom.
• Live online with an instructor present in real time, capped at 20 students per instructor.
• Hybrid or asynchronous online with board approval, capped at 30 students per instructor.

Regardless of format, theory hours are separate from lab and clinical hours and cannot be substituted for them. A program advertising "online CNA training" in Washington can move only the 35 theory hours online; the remaining 73 hours are in person. The details and limits are in online CNA classes in Washington.

What a theory day looks like in a 4-week program

In a condensed program, a typical theory block runs as a lecture segment, a discussion of a case, and a short quiz. Instructors, who under WAC 246-841A-430 must be licensed nurses with recent direct-care experience, tend to teach from patient scenarios rather than from the textbook alone. Expect reading assignments between sessions, since 35 hours is not enough time to read the textbook in class. A study method suited to the pace is described in studying for CNA class.

Theory and the knowledge test

The $55 Credentia knowledge test measures the same content the theory hours teach. The test's content areas align with the federal nurse aide competency categories, which overlap almost exactly with the 12 WABON areas. Students who treat theory as a box to check and rely on lab practice alone tend to struggle on the knowledge test, because it asks about reasons, normal ranges, and reporting rules rather than hand movements. The test format and content weighting are in the Credentia knowledge test for Washington CNAs.

How the 35 hours compare with other states

The federal floor for total nurse aide training is 75 hours, with at least 16 hours of supervised practical training and at least 16 hours of classroom instruction in specified topics before resident contact. Washington's 35-hour theory minimum and 108-hour total sit well above that floor, which is one reason out-of-state aides moving to Washington sometimes need additional training. For the state-by-state context, see Washington State CNA requirements in 2026.

Frequently asked questions

How many classroom hours does a Washington CNA program require? At least 35 hours of classroom theory, as part of a 108-hour minimum that also includes 33 skills lab hours and 40 clinical hours.

Can CNA theory be taken online in Washington? Yes. Theory may be delivered in person, live online (20 students per instructor), or in an approved hybrid format (30 per instructor). Lab and clinical hours must be in person.

What topics are in CNA theory? The 12 WABON core competencies, which include the nursing assistant role, resident rights, communication, infection control, safety, basic nursing skills, restorative care, personal care, life transitions, developmental disabilities, mental health, and cognitive impairment.

Is there a test at the end of theory? Programs give their own quizzes and a final, and the state's $55 Credentia knowledge test covers the same content after you pass the skills test.

Do theory hours count toward the NAR four-month deadline? The deadline covers completing the whole program and passing the exam, so every theory hour is part of the clock.

Theory is the first of the three training blocks; the next two are described in inside the CNA skills lab and CNA clinical rotations in Washington. Huduma's CNA Traditional program covers all 108 hours in 4 weeks.
