Bellevue College might be the biggest, but its far from the best. They tend to hire current UW professors to teach one class a quarter, stuff the rest of the dept with teachers that were able to get canned at the Seattle Colleges and UW satellites, and hope for the best.

Many of my friends who went there have horror stories about their teachers which I'd be hard pressed to encounter at Seattle Central College or North Seattle College.

Nearly every community college in the Puget Sound decided about a decade ago to shed the community branding and add a handful of 4 year degrees. Problem is the material you learn in upper level CS classes at UW and its satellites is quite different than what North Seattle College and Seattle Central College require (eg: a whole class on SQL Server, C# as the Intro CS class at Seattle Central rathr than the state mandated Python, etc).
