Stars not in alignment as state unveils its school-ranking system

Nevada’s school rating system, which was inspired by a similar system developed under former Clark County Schools Superintendent Dwight Jones, measures school performance on several factors:

• Growth (40 percent of rating): How much students improved on standardized tests

• Proficiency (30 percent): Students’ passing rates on state tests

• Gap reduction (20 percent): How much schools were able to close the achievement gaps between different student groups

• Other indicators (10 percent): Includes average daily school attendance, and for high schools, their graduation rates and “college readiness,” which is based on students’ participation rates and scores in college-level Advanced Placement and International Baccalaureate courses.
