In Nevada, school districts are countywide, giving the state 17 districts, the largest of which is Clark County School District (CCSD). Nearly 70% of the entire state's population resides in this county. For the past 10 years, population growth in this county has been the fastest in the nation. Such growth brings challenges especially with NCLB, which greatly expands the federal role in public education. Strict accountability is a key piece of NCLB, and Clark County, like all districts, has begun working toward these mandated goals. However, size and growth challenge large urban school districts in terms of communicating to the public with both accuracy and understandability. (Contains 2 figures.)
