What makes Washington different
- Washington offers “bridge” programs for home care aides and medical assistants moving to nursing assistant certification.
- We have not yet verified the current (2026) Washington fee schedule from a primary source, so fees are not listed here.

Federal minimums that apply everywhere
Federal rules set the floor for every state: nurse aide training must be at least 75 clock hours, including at least 16 hours of supervised practical training (42 CFR 483.152). States can require more. After you are certified, going 24 consecutive months without paid nursing-related work means retraining or retesting before you can work in a Medicare/Medicaid nursing home (42 CFR 483.35(d)).
