Washington continuing education requirements include:

15 hours annually would total 30 hours over two years in terms of quantity, but this is not how Washington structures its requirement — the state uses a two-year renewal cycle with 30 hours total, not an annual reporting structure, making this answer technically incorrect in its framing.

45 hours every three years is not Washington's requirement — this figure might be confused with other professional licensing requirements in different states or fields, but Washington's real estate CE is specifically 30 hours on a two-year cycle.

Claiming no continuing education is required is entirely false — Washington has mandatory CE requirements codified in WAC 308-124H, and failure to comply results in license non-renewal; this answer would only apply to a state that grandfathers in licensees without CE, which Washington does not do.
